+Django ORM / Mongoengine style ORM for Cassandra
+
+In it's current state you can define column families, create and delete column families
+based on your model definiteions, save models and retrieve models by their primary keys.
+
+That's about it. Also, there are only 2 tests and the CQL stuff is very simplistic at this point.
+
+##TODO
+* dynamic column support
+* return None when row isn't found in find()
+* tests
+* query functionality
+* nice column and model class __repr__

 ===============
 
-Django ORM / Mongoengine style ORM for Cassandra
+Python Cassandra ORM in the style of django / mongoengine
 
 In it's current state you can define column families, create and delete column families
 based on your model definiteions, save models and retrieve models by their primary keys.
 
-That's about it. Also, there are only 2 tests and the CQL stuff is very simplistic at this point.
+That's about it. Also, the CQL stuff is pretty simple at this point.
 
 ##TODO
+* Complex queries (class Q(object))
+* Match column names to mongoengine field names?
+* mongoengine fields? URLField, EmbeddedDocument, ListField, DictField
+* column ttl?
+* ForeignKey/DBRef fields?
 * dynamic column support
-* return None when row isn't found in find()
 * tests
 * query functionality
 * nice column and model class __repr__

 ===============
 
-Cassandra ORM for Python in the style of the Django orm and mongoengine
+cqlengine is a Cassandra CQL ORM for Python in the style of the Django orm and mongoengine
 
-In it's current state you can define column families, create and delete column families
-based on your model definiteions, save models and retrieve models by their primary keys.
+[Documentation](https://github.com/bdeggleston/cqlengine/wiki/cqlengine-documentation)
 
-That's about it. Also, the CQL stuff is very basic at this point.
+[Report a Bug](https://github.com/bdeggleston/cqlengine/issues)
 
-##TODO
-* column ttl?
-* ForeignKey/DBRef fields?
-* query functionality
-* Match column names to mongoengine field names?
-* nice column and model class __repr__
+[Users Mailing List](https://groups.google.com/forum/?fromgroups#!forum/cqlengine-users)
 
+[Dev Mailing List](https://groups.google.com/forum/?fromgroups#!forum/cqlengine-dev)
 
+## Installation
+TODO
+
+## Getting Started
+
+```python
+#first, define a model
+>>> from cqlengine import columns
+>>> from cqlengine.models import Model
+
+>>> class ExampleModel(Model):
+>>>     example_id      = columns.UUID(primary_key=True)  
+>>>     example_type    = columns.Integer(index=True)
+>>>     created_at      = columns.DateTime()
+>>>     description     = columns.Text(required=False)
+
+#next, setup the connection to your cassandra server(s)...
+>>> from cqlengine import connection
+>>> connection.setup(['127.0.0.1:9160'])
+
+#...and create your CQL table
+>>> from cqlengine.management import create_column_family
+>>> create_column_family(ExampleModel)
+
+#now we can create some rows:
+>>> em1 = ExampleModel.objects.create(example_type=0, description="example1")
+>>> em2 = ExampleModel.objects.create(example_type=0, description="example2")
+>>> em3 = ExampleModel.objects.create(example_type=0, description="example3")

+>>> em5 = ExampleModel.objects.create(example_type=1, description="example5")
+>>> em6 = ExampleModel.objects.create(example_type=1, description="example6")
+>>> em7 = ExampleModel.objects.create(example_type=1, description="example7")
+>>> em8 = ExampleModel.objects.create(example_type=1, description="example8")
+# Note: the UUID and DateTime columns will create uuid4 and datetime.now
+# values automatically if we don't specify them when creating new rows
+
+#and now we can run some queries against our table
+>>> ExampleModel.objects.count()

+>>> q = ExampleModel.objects(example_type=1)
+>>> q.count()

+>>> for instance in q:
+>>>     print q.description
+example5
+example6
+example7
+example8
+
+#here we are applying additional filtering to an existing query
+#query objects are immutable, so calling filter returns a new
+#query object
+>>> q2 = q.filter(example_id=em5.example_id)
+
+>>> q2.count()

+Models
+======
+
+.. module:: cqlengine.models
+
+A model is a python class representing a CQL table.
+
+Example
+=======
+
+This example defines a Person table, with the columns ``first_name`` and ``last_name``
+
+.. code-block:: python
+
+    from cqlengine import columns
+    from cqlengine.models import Model
+    
+    class Person(Model):
+        first_name  = columns.Text()
+        last_name = columns.Text()
+     
+
+The Person model would create this CQL table:
+
+.. code-block:: sql
+
+   CREATE TABLE cqlengine.person (
+       id uuid,
+       first_name text,
+       last_name text,
+       PRIMARY KEY (id)
+   )
+
+Columns
+=======
+
+    Columns in your models map to columns in your CQL table. You define CQL columns by defining column attributes on your model classes. For a model to be valid it needs at least one primary key column (defined automatically if you don't define one) and one non-primary key column.
+
+    Just as in CQL, the order you define your columns in is important, and is the same order they are defined in on a model's corresponding table.
+
+Column Types
+============
+
+    Each column on your model definitions needs to an instance of a Column class. The column types that are included with cqlengine as of this writing are:
+
+    * :class:`~cqlengine.columns.Bytes`
+    * :class:`~cqlengine.columns.Ascii`
+    * :class:`~cqlengine.columns.Text`
+    * :class:`~cqlengine.columns.Integer`
+    * :class:`~cqlengine.columns.DateTime`
+    * :class:`~cqlengine.columns.UUID`
+    * :class:`~cqlengine.columns.Boolean`
+    * :class:`~cqlengine.columns.Float`
+    * :class:`~cqlengine.columns.Decimal`
+
+    A time uuid field is in the works.
+
+Column Options
+--------------
+
+    Each column can be defined with optional arguments to modify the way they behave. While some column types may define additional column options, these are the options that are available on all columns:
+
+    :attr:`~cqlengine.columns.BaseColumn.primary_key`
+        If True, this column is created as a primary key field. A model can have multiple primary keys. Defaults to False.
+
+        *In CQL, there are 2 types of primary keys: partition keys and clustering keys. As with CQL, the first primary key is the partition key, and all others are clustering keys.*
+
+    :attr:`~cqlengine.columns.BaseColumn.index`
+        If True, an index will be created for this column. Defaults to False.
+        
+        *Note: Indexes can only be created on models with one primary key*
+
+    :attr:`~cqlengine.columns.BaseColumn.db_field`
+        Explicitly sets the name of the column in the database table. If this is left blank, the column name will be the same as the name of the column attribute. Defaults to None.
+
+    :attr:`~cqlengine.columns.BaseColumn.default`
+        The default value for this column. If a model instance is saved without a value for this column having been defined, the default value will be used. This can be either a value or a callable object (ie: datetime.now is a valid default argument).
+
+    :attr:`~cqlengine.columns.BaseColumn.required`
+        If True, this model cannot be saved without a value defined for this column. Defaults to True. Primary key fields cannot have their required fields set to False.
+
+Model Methods
+=============
+    Below are the methods that can be called on model instances.
+
+.. class:: Model(\*\*values)
+
+    Creates an instance of the model. Pass in keyword arguments for columns you've defined on the model.
+
+    *Example*
+
+    .. code-block:: python
+        
+        #using the person model from earlier:
+        class Person(Model):
+            first_name  = columns.Text()
+            last_name = columns.Text()
+
+        person = Person(first_name='Blake', last_name='Eggleston')
+        person.first_name  #returns 'Blake'
+        person.last_name  #returns 'Eggleston'
+        
+
+    .. method:: save()
+
+        Saves an object to the database
+
+        *Example*
+
+        .. code-block:: python
+
+            #create a person instance
+            person = Person(first_name='Kimberly', last_name='Eggleston')
+            #saves it to Cassandra
+            person.save()
+
+
+    .. method:: delete()
+    
+        Deletes the object from the database.
+
+Model Attributes
+================
+
+    .. attribute:: Model.db_name
+
+        *Optional.* Sets the name of the CQL table for this model. If left blank, the table name will be the name of the model, with it's module name as it's prefix
+
+    .. attribute:: Model.keyspace
+
+        *Optional.* Sets the name of the keyspace used by this model. Defaulst to cqlengine
+
+Automatic Primary Keys
+======================
+    CQL requires that all tables define at least one primary key. If a model definition does not include a primary key column, cqlengine will automatically add a uuid primary key column named ``id``.

+Making Queries
+==============
+
+.. module:: cqlengine.query
+
+Retrieving objects
+==================
+    Once you've populated Cassandra with data, you'll probably want to retrieve some of it. This is accomplished with QuerySet objects. This section will describe how to use QuerySet objects to retrieve the data you're looking for.
+
+Retrieving all objects
+----------------------
+    The simplest query you can make is to return all objects from a table.
+
+    This is accomplished with the ``.all()`` method, which returns a QuerySet of all objects in a table
+
+    Using the Person example model, we would get all Person objects like this:
+
+    .. code-block:: python
+
+        all_objects = Person.objects.all()
+
+.. _retrieving-objects-with-filters:
+
+Retrieving objects with filters
+----------------------------------------
+    Typically, you'll want to query only a subset of the records in your database.
+
+    That can be accomplished with the QuerySet's ``.filter(\*\*)`` method.
+
+    For example, given the model definition:
+    
+    .. code-block:: python
+        
+        class Automobile(Model):
+            manufacturer = columns.Text(primary_key=True)
+            year = columns.Integer(primary_key=True)
+            model = columns.Text()
+            price = columns.Decimal()
+
+    ...and assuming the Automobile table contains a record of every car model manufactured in the last 20 years or so, we can retrieve only the cars made by a single manufacturer like this:
+
+    
+    .. code-block:: python
+
+        q = Automobile.objects.filter(manufacturer='Tesla')
+
+    We can then further filter our query with another call to **.filter**
+
+    .. code-block:: python
+
+        q = q.filter(year=2012)
+
+    *Note: all queries involving any filtering MUST define either an '=' or an 'in' relation to either a primary key column, or an indexed column.*
+
+Accessing objects in a QuerySet
+===============================
+
+    There are several methods for getting objects out of a queryset
+
+    * iterating over the queryset

+Filtering Operators
+===================
+
+    :attr:`Equal To <query.QueryOperator.EqualsOperator>`
+
+        The default filtering operator.
+
+        .. code-block:: python
+
+            q = Automobile.objects.filter(manufacturer='Tesla')
+            q = q.filter(year=2012)  #year == 2012
+
+    In addition to simple equal to queries, cqlengine also supports querying with other operators by appending a ``__<op>`` to the field name on the filtering call
+
+    :attr:`in (__in) <query.QueryOperator.InOperator>`
+
+        .. code-block:: python
+
+            q = Automobile.objects.filter(manufacturer='Tesla')
+            q = q.filter(year__in=[2011, 2012])
+
+    :attr:`> (__gt) <query.QueryOperator.GreaterThanOperator>`
+
+        .. code-block:: python
+
+            q = Automobile.objects.filter(manufacturer='Tesla')
+            q = q.filter(year__gt=2010)  # year > 2010
+
+    :attr:`>= (__gte) <query.QueryOperator.GreaterThanOrEqualOperator>`
+
+        .. code-block:: python
+
+            q = Automobile.objects.filter(manufacturer='Tesla')
+            q = q.filter(year__gte=2010)  # year >= 2010
+
+    :attr:`< (__lt) <query.QueryOperator.LessThanOperator>`
+
+        .. code-block:: python
+
+            q = Automobile.objects.filter(manufacturer='Tesla')
+            q = q.filter(year__lt=2012)  # year < 2012
+
+    :attr:`<= (__lte) <query.QueryOperator.LessThanOrEqualOperator>`
+
+        .. code-block:: python
+
+            q = Automobile.objects.filter(manufacturer='Tesla')
+            q = q.filter(year__lte=2012)  # year <= 2012
+
+QuerySets are imutable
+======================
+
+    When calling any method that changes a queryset, the method does not actually change the queryset object it's called on, but returns a new queryset object with the attributes of the original queryset, plus the attributes added in the method call.
+
+    *Example*
+
+    .. code-block:: python
+
+        #this produces 3 different querysets
+        #q does not change after it's initial definition
+        q = Automobiles.objects.filter(year=2012)
+        tesla2012 = q.filter(manufacturer='Tesla')
+        honda2012 = q.filter(manufacturer='Honda')
+
+Ordering QuerySets
+==================
+
+    Since Cassandra is essentially a distributed hash table on steroids, the order you get records back in will not be particularly predictable.
+
+    However, you can set a column to order on with the ``.order_by(column_name)`` method. 
+
+    *Example*
+
+    .. code-block:: python
+
+        #sort ascending
+        q = Automobiles.objects.all().order_by('year')
+        #sort descending
+        q = Automobiles.objects.all().order_by('-year')
+
+    *Note: Cassandra only supports ordering on a clustering key. In other words, to support ordering results, your model must have more than one primary key, and you must order on a primary key, excluding the first one.*
+
+    *For instance, given our Automobile model, year is the only column we can order on.*
+
+QuerySet method reference
+=========================
+
+.. class:: QuerySet
+
+    .. method:: all()
+
+        Returns a queryset matching all rows
+
+    .. method:: count()
+
+        Returns the number of matching rows in your QuerySet
+
+    .. method:: filter(\*\*values)
+
+        :param values: See :ref:`retrieving-objects-with-filters`
+
+        Returns a QuerySet filtered on the keyword arguments
+
+    .. method:: get(\*\*values)
+
+        :param values: See :ref:`retrieving-objects-with-filters`
+
+        Returns a single object matching the QuerySet. If no objects are matched, a :attr:`~models.Model.DoesNotExist` exception is raised. If more than one object is found, a :attr:`~models.Model.MultipleObjectsReturned` exception is raised.
+
+    .. method:: limit(num)
+
+        Limits the number of results returned by Cassandra.
+        
+        *Note that CQL's default limit is 10,000, so all queries without a limit set explicitly will have an implicit limit of 10,000*
+
+    .. method:: order_by(field_name)
+
+        :param field_name: the name of the field to order on. *Note: the field_name must be a clustering key*
+        :type field_name: string
+
+        Sets the field to order on.

+Collection Type Columns
+----------------------------
+
+    CQLEngine also supports container column types. Each container column requires a column class argument to specify what type of objects it will hold. The Map column requires 2, one for the key, and the other for the value
+    
+    *Example*
+
+    .. code-block:: python
+        
+        class Person(Model):
+            first_name  = columns.Text()
+            last_name   = columns.Text()
+
+            friends     = columns.Set(columns.Text)
+            enemies     = columns.Set(columns.Text)
+            todo_list   = columns.List(columns.Text)
+            birthdays   = columns.Map(columns.Text, columns.DateTime)
+        
+
+
+.. class:: Set()
+
+    Stores a set of unordered, unique values. Available only with Cassandra 1.2 and above ::
+
+        columns.Set(value_type)
+
+    **options**
+
+        :attr:`~columns.Set.value_type`
+            The type of objects the set will contain
+
+        :attr:`~columns.Set.strict`
+            If True, adding this column will raise an exception during save if the value is not a python `set` instance. If False, it will attempt to coerce the value to a set. Defaults to True.
+
+.. class:: List()
+
+    Stores a list of ordered values. Available only with Cassandra 1.2 and above ::
+
+        columns.List(value_type)
+
+    **options**
+
+        :attr:`~columns.List.value_type`

+    Stores a map (dictionary) collection, available only with Cassandra 1.2 and above ::

+TimeUUID Functions
+==================
+
+    In addition to querying using regular values, there are two functions you can pass in when querying TimeUUID columns to help make filtering by them easier. Note that these functions don't actually return a value, but instruct the cql interpreter to use the functions in it's query.

+Batch Queries
+===============
+
+    cqlengine now supports batch queries using the BatchQuery class. Batch queries can be started and stopped manually, or within a context manager. To add queries to the batch object, you just need to precede the create/save/delete call with a call to batch, and pass in the batch object. 
+    
+    You can only create, update, and delete rows with a batch query, attempting to read rows out of the database with a batch query will fail.
+
+    .. code-block:: python
+        
+        from cqlengine import BatchQuery
+
+        #using a context manager
+        with BatchQuery() as b:
+            now = datetime.now()

Subject: [PATCH 0180/4528] Allow `datetime.date` values with
 `columns.DateTime`.

Adds support for setting a `datetime.date` value to a `DateTime`
column. The value will be transparently converted to a
`datetime.datetime` with the time components set to zero.

Subject: [PATCH 0204/4528] Getting connection pooling working with mocking
 library

Verified throwing exception when no servers are available,
but correctly recovering and hitting the next server when
one is.

fixing minor pooling tests

ensure we get the right exception back when no servers are available

working on tests for retry

connections working despite failure

Removed old connection_manager and replaced with a simple context
manager that allows for easy access to clients within the main pool

+Table Polymorphism
+==================
+
+    As of cqlengine 0.8, it is possible to save and load different model classes using a single CQL table.

+
+    For instance, suppose you want a table that stores rows of pets owned by an owner:
+
+    .. code-block:: python
+
+        class Pet(Model):
+            __table_name__ = 'pet'
+            owner_id = UUID(primary_key=True)
+            pet_id = UUID(primary_key=True)
+            pet_type = Text(polymorphic_key=True)
+            name = Text()
+
+            def eat(self, food):
+                pass
+
+            def sleep(self, time):
+                pass
+
+        class Cat(Pet):
+            __polymorphic_key__ = 'cat'
+            cuteness = Float()
+
+            def tear_up_couch(self):
+                pass
+
+        class Dog(Pet):
+            __polymorphic_key__ = 'dog'
+            fierceness = Float()
+
+            def bark_all_night(self):
+                pass
+
+    After calling ``sync_table`` on each of these tables, the columns defined in each model will be added to the
+    ``pet`` table. Additionally, saving ``Cat`` and ``Dog`` models will save the meta data needed to identify each row
+    as either a cat or dog.
+
+    To setup a polymorphic model structure, follow these steps
+
+    1.  Create a base model with a column set as the polymorphic_key (set ``polymorphic_key=True`` in the column definition)
+    2.  Create subclass models, and define a unique ``__polymorphic_key__`` value on each
+    3.  Run ``sync_table`` on each of the sub tables
+
+    **About the polymorphic key**
+
+    The polymorphic key is what cqlengine uses under the covers to map logical cql rows to the appropriate model type. The
+    base model maintains a map of polymorphic keys to subclasses. When a polymorphic model is saved, this value is automatically
+    saved into the polymorphic key column. You can set the polymorphic key column to any column type that you like, with
+    the exception of container and counter columns, although ``Integer`` columns make the most sense. Additionally, if you
+    set ``index=True`` on your polymorphic key column, you can execute queries against polymorphic subclasses, and a
+    ``WHERE`` clause will be automatically added to your query, returning only rows of that type. Note that you must
+    define a unique ``__polymorphic_key__`` value to each subclass, and that you can only assign a single polymorphic
+    key column per model
+
+
+Extending Model Validation
+==========================
+
+    Each time you save a model instance in cqlengine, the data in the model is validated against the schema you've defined
+    for your model. Most of the validation is fairly straightforward, it basically checks that you're not trying to do
+    something like save text into an integer column, and it enforces the ``required`` flag set on column definitions.
+    It also performs any transformations needed to save the data properly.
+
+    However, there are often additional constraints or transformations you want to impose on your data, beyond simply
+    making sure that Cassandra won't complain when you try to insert it. To define additional validation on a model,
+    extend the model's validation method:
+
+    .. code-block:: python
+
+        class Member(Model):
+            person_id = UUID(primary_key=True)
+            name = Text(required=True)
+
+            def validate(self):
+                super(Member, self).validate()
+                if self.name == 'jon':
+                    raise ValidationError('no jon\'s allowed')
+
+    *Note*: while not required, the convention is to raise a ``ValidationError`` (``from cqlengine import ValidationError``)
+    if validation fails
+
+
 Compaction Options

Subject: [PATCH 0401/4528] First cut at a gevent connection class.

It seems to kind of work. The integration tests aren't working
right; that needs to be fixed before first. A simple test of the
basic functionality seems to work, but I've not yet tested the
recovery/retry and other execptional conditions.

Subject: [PATCH 0565/4528] Use WeakValueDictionary for prepared statements

When nodes are added or come back up after being down,
all known prepared statements are re-prepared on them.
In order to avoid preparing statements that will never
be used again, we'll use a dictionary of weak references
to the statements so that once they are GC'ed, they are
removed from our cache.

Subject: [PATCH 0568/4528] Libev performance, safety, and error handling
 improvements

This commit does several things:
 * check for LIBEV_ERROR flags on read and write notifications.
   (Typically socket.recv() or socket.send() will error correctly,
    but it's safer to also check for this flag in multithreaded
    environments.)
 * Use a separate lock for maniuplating the queue of pending
   messages to be sent
 * Notify the event loop of watcher changes more frequently in
   order to avoid waiting to execute pending events

Subject: [PATCH 0570/4528] Specify version in install instructions

Earlier beta versions (eg 1.0.0-beta4) used a non-PEP426 compliant version
which happens to sort higher than the compliant version (eg 1.0.0b6),
so to ensure the correct version is installed, the version must
explicitly be specified.

+1.0.0b7
+=======
+Nov 12, 2013
+
+This release makes many stability improvements, especially around
+prepared statements and node failure handling.  In particular,
+several cases where a request would never be completed (and as a
+result, leave the application hanging) have been resolved.
+
+Features
+--------
+* Add `timeout` kwarg to ``ResponseFuture.result()``
+* Create connection pools to all hosts in parallel when initializing
+  new Sesssions.
+
+Bug Fixes
+---------
+* Properly set exception on ResponseFuture when a query fails
+  against all hosts
+* Improved cleanup and reconnection efforts when reconnection fails
+  on a node that has recently come up
+* Use correct consistency level on when retrying failed operations
+  against a different host. (An invalid consistency level was being
+  used, causing the retry to fail.)
+* Better error messages for failed prepare() opertaions
+* Prepare new statements against all hosts in parallel (formerly
+  sequential)
+* Fix failure to save the new current keyspace on connections. (This
+  could cause problems for prepared statements and lead to extra
+  operations to continuously re-set the keyspace)
+* Avoid sharing LoadBalancingPolicies across Cluster instances. (When a second
+  Cluster was connected, it effectively mark nodes down for the first Cluster.)
+* Better handling of failures during the re-preparation sequence for unrecognized
+  prepared statements
+* Throttle trashing of underutilized connections to avoid trashing newly
+  created connections
+* Fix race condition which could result in trashed connections being closed
+  before the last operations had completed
+* Avoid preparing statements on the event loop thread (which could lead to
+  deadlock)
+* Correctly mark up non-contact point nodes discovered by the control
+  connection. (This lead to prepared statements not being prepared
+  against those hosts, generating extra traffic later when the
+  statements were executed and unrecognized.)
+* Correctly handle large messages through libev
+* Add timeout to schema agreement check queries
+* More complete (and less contended) locking around manipulation of the
+  pending message deque for libev connections
+
+Other
+-----
+* Prepare statements in batches of 10. (When many prepared statements
+  are in use, this allows the driver to start utilizing nodes that
+  were restarted more quickly.)
+* Better debug logging around connection management
+* Don't retain unreferenced prepared statements in the local cache.
+  (If many different prepared statements were created, this would
+  increase memory usage and greatly increase the amount of time
+  required to being utilizing a node that was added or marked
+  up.)

I used the gcc-python-plugin's gcc-with-cpychecker tool as
described here:
http://gcc-python-plugin.readthedocs.org/en/latest/cpychecker.html#gcc-with-cpychecker

Note that the checker does still have some bugs, so it will raise errors
with the current code.

Subject: [PATCH 0590/4528] Fixed a bug when NetworkTopologyStrategy is used.

Although the Cassandra documentation implies that the
`replication_factor` parameter would be ignored in this case its
presence will cause an error when creating a keyspace using
NetworkTopologyStrategy.

Subject: [PATCH 0615/4528] Use CL.ONE explicitly when interacting with the
 system keyspace

The system keyspace uses  "LocalStrategy" for replication so it needs to
be accessed with CL.ONE. If the default consistency level is set to
something else all management commands which rely on introspecting the
system keyspace will fail.

+

Subject: [PATCH 0637/4528] Fix logic determining if compaction options need
 syncing

The compaction_strategy_options as received from the
`system.schema_columnfamilies` table are all string valued and
comparison to typed values (ints, floats) as defined in models results
in sync_table() issuning ALTER TABLE statements redundantly even if
there were no changes to compaction options.

This patch casts the values defined in models to strings to ensure they
compare equal as needed.

Additionally, this patch normalizes handling of the `min_threshold` and
`max_threshold` options for SizeTieredCompactionStrategy which exist
outside the `compaction_strategy_options` mapping and have different
names in the `system.schema_columnfamilies` table compared to the CQL
options.

A typo in the `BaseModel.__compaction_tombstone_threshold__` option is
also fixed.

Subject: [PATCH 0651/4528] Use same conn to check schema agreement

Before doing this, the control connection would be used to check
for schema agreement.  The schema check could occasionally complete
before the node that the control connection was open to had even
registered the schema change.  By re-using the connection that the
schema change was performed on, we avoid this race condition.

Fixes PYTHON-33

Subject: [PATCH 0655/4528] Use select backend for libev

It appears that the epoll backend may have been causing the hanging
write requests at the connection level, which appears to be the last
major cause of PYTHON-27, PYTHON-29, and PYTHON-32.  For now, we will
hardcode select as the libev backend; this would be the best choice in
almost all circumstances, in any case.

Subject: [PATCH 0656/4528] Preserve milli-precision in non-prepared datetimes

When a datetime was used for a 'timestamp' value in a non-prepared
statement, all sub-second precision was lost.  After this change,
millisecond level precision will be kept.

PyErr_SetFromErrno() will result in PyThreadState_Get() being called,
which explicitly states that the GIL must be held when it is called.
Before this fix, the process could segfault.

Previously, the error would be set for the current thread, so whatever
the next line of Python that was interpreted in that thread was would
see the error.  Instead, this passes the errno to the appropriate
handler function, allowing the connection to be defuncted.

+1.0.0 Final
+===========
+(In Progress)
+
+Bug Fixes
+---------
+* Prevent leak of Scheduler thread (even with proper shutdown)
+* Correctly handle ignored hosts, which are common with the
+  DCAwareRoundRobinPolicy
+* Hold strong reference to prepared statement while executing it to avoid
+  garbage collection
+* Add NullHandler logging handler to the cassandra package to avoid
+  warnings about there being no configured logger
+* Fix bad handling of nodes that have been removed from the cluster
+* Properly escape string types within cql collections
+* Handle setting the same keyspace twice in a row
+* Avoid race condition during schema agreement checks that could result
+  in schema update queries returning before all nodes had seen the change
+* Preserve millisecond-level precision in datetimes when performing inserts
+  with simple (non-prepared) statements
+* Properly defunct connections when libev reports an error by setting
+  errno instead of simply logging the error
+* Fix endless hanging of some requests when using the libev reactor
+
+Features
+--------
+* Add default query timeout to ``Session``
+* Add timeout parameter to ``Session.execute()``
+* Add ``WhiteListRoundRobinPolicy`` as a load balancing policy option
+* Support for consistency level ``LOCAL_ONE``
+
+Other
+-----
+* Raise Exception if ``TokenAwarePolicy`` is used against a cluster using the
+  ``Murmur3Partitioner`` if the murmur3 C extension has not been compiled
+* Add encoder mapping for ``OrderedDict``
+* Use timeouts on all control connection queries
+* Benchmark improvements, including command line options and eay
+  multithreading support
+* Reduced lock contention when using the asyncore reactor
+

Subject: [PATCH 0701/4528] Hold deque lock when popping in asyncore

In multithreaded environments, this could result in corruption of the
deque, leading to malformed messages.

Additionally, this change attempts multiple writes whenever select()
reports that the FD is available for writing, similar to what is already
done for libev.

Under certain conditions, when a connection was closed by the server,
the close() method would first be called, followed by the defunct()
method shortly afterwards.  Both of these would error out all callbacks.

This avoids doing "defunct" work if the connection is already closed,
and holds a lock to avoid any other race conditions which might result
in erroring all callbacks twice.

Subject: [PATCH 0714/4528] Ensure in_flight is decremented when ops time out

Internal operations, such as control connection queries and preparing of
statements, use a different method for synchronously executing queries.
If those timed out, the in_flight count for the relevant connection
would not be decremented, leaving the connection to appear more busy
than it actually was.

+Getting Started
+===============
+
+Before we can start executing any queries against Cassandra we need to setup our cluster. Setting up our cluster
+allows us to set specific options like what port CQL native transport is listening to for connections, SSL options,
+the loadbalancing policy to use for handling queries and more which can be found here :doc:`/api/cassandra/cluster` ::
+
+  from cassandra.cluster import Cluster
+
+  options = {
+      'contact_points': ['10.1.1.3', '10.1.1.4', '10.1.1.5'],
+      'port': 9042
+  }
+
+  cluster = Cluster(**options)
+  session = cluster.connect(keyspace='users')
+
+Instantiating a cluster does not actually connect us to any nodes. To begin executing queries we need a session, which is created by calling cluster.connect(). connect takes an optional 'keyspace' argument allowing all queries in that session to be operated on that keyspace. Alternatively, you can set the keyspace after the session is created. Sessions should NOT be instantiated outside the use of a Cluster. The Cluster handles the
+creation and disposal of sessions. ::
+
+  session.set_keyspace('users')
+
+Now that we have a session we can begin to execute queries. If you are using Cassandra in a way that allows you to not block calls you can execute queries asynchronously. More about the execute and execute_async functions can be found here :doc:`/api/cassandra/cluster` (this should link to execute and execute_async) ::
+
+  # without async (blocking)
+  result = session.execute('SELECT * FROM users')
+  for row in results:
+      print row
+
+  # with async
+  def handle_success(results):
+      for row in results:
+          print row
+
+  def handle_error(exception_error):
+      print exception_error
+
+  future = session.execute_async('SELECT * FROM users')
+  future.add_callbacks(handle_success, handle_error)
+
+When executing queries from a session, the driver picks a Cassandra node to act as the coordinator. As shown earlier in our Cluster example with the options we passed several ip addresses which the driver can communicate with. By default the driver will touch those nodes in the list and grab the ip addresses of any nodes that those nodes have found via gossip.

 Getting Started
 ===============
 
-Before we can start executing any queries against Cassandra we need to setup our cluster. Setting up our cluster
-allows us to set specific options like what port CQL native transport is listening to for connections, SSL options,
-the loadbalancing policy to use for handling queries and more which can be found here :doc:`/api/cassandra/cluster` ::
+First, make sure you have the driver properly :doc:`installed <installation>`.
 
-  from cassandra.cluster import Cluster
+Connecting to Cassandra
+-----------------------
+Before we can start executing any queries against Cassandra we need to setup
+our :class:`~.Cluster`. As the name suggests, you will typically have one
+instance of :class:`~.Cluster` for each Cassandra cluster you want to interact
+with.
 
-  options = {
-      'contact_points': ['10.1.1.3', '10.1.1.4', '10.1.1.5'],
-      'port': 9042
-  }
+The simplest way to create a :class:`~.Cluster` is like this
 
-  cluster = Cluster(**options)
-  session = cluster.connect(keyspace='users')
+.. code-block:: python
 
-Instantiating a cluster does not actually connect us to any nodes. To begin executing queries we need a session, which is created by calling cluster.connect(). connect takes an optional 'keyspace' argument allowing all queries in that session to be operated on that keyspace. Alternatively, you can set the keyspace after the session is created. Sessions should NOT be instantiated outside the use of a Cluster. The Cluster handles the
-creation and disposal of sessions. ::
+    from cassandra.cluster import Cluster
+    cluster = Cluster(['10.1.1.3', '10.1.1.4', '10.1.1.5'])
 
-  session.set_keyspace('users')
+The set of IP addresses we pass to the :class:`~.Cluster` are simply
+an initial set of contact points.  After the driver connects to one
+of these addresses it will automatically discover the rest of the
+nodes in the cluster and connect to them, so you don't need to list
+every node in your cluster.
 
-Now that we have a session we can begin to execute queries. If you are using Cassandra in a way that allows you to not block calls you can execute queries asynchronously. More about the execute and execute_async functions can be found here :doc:`/api/cassandra/cluster` (this should link to execute and execute_async) ::
+If you need to use a non-standard port, use SSL, or customize the driver's
+behavior in some other way, this is the place to do it:
 
-  # without async (blocking)
-  result = session.execute('SELECT * FROM users')
-  for row in results:
-      print row
+.. code-block:: python
 
-  # with async
-  def handle_success(results):
-      for row in results:
-          print row
+    from cassandra.cluster import Cluster
+    from cassandra.polices import DCAwareRoundRobinPolicy
 
-  def handle_error(exception_error):
-      print exception_error
+    cluster = Cluster(
+        contact_points=['10.1.1.3', '10.1.1.4', '10.1.1.5'],
+        load_balancing_policy=DCAwareRoundRobinPolicy(local_dc='US_EAST'),
+        port=9042)
 
-  future = session.execute_async('SELECT * FROM users')
-  future.add_callbacks(handle_success, handle_error)
 
-When executing queries from a session, the driver picks a Cassandra node to act as the coordinator. As shown earlier in our Cluster example with the options we passed several ip addresses which the driver can communicate with. By default the driver will touch those nodes in the list and grab the ip addresses of any nodes that those nodes have found via gossip. To change this behavior you can use different Load Balancing policies that are available here :doc:`/api/cassandra/policies` ::
+You can find a more complete list of options in the :class:`~.Cluster` documentation.
 
-  from cassandra.cluster import Cluster
-  from cassandra.policies import DCAwareRoundRobinPolicy
+Instantiating a :class:`~.Cluster` does not actually connect us to any nodes.
+To establish connections and begin executing queries we need a
+:class:`~.Session`, which is created by calling :meth:`.Cluster.connect()`.
+The :meth:`~.Cluster.connect()` method takes an optional ``keyspace`` argument
+which sets the default keyspace for all queries made through that :class:`~.Session`:
 
-  options = {
-      'contact_points': ['10.1.1.3', '10.1.1.4', '10.1.1.5'],
-      'port': 9042,
-      'load_balancing_policy': DCAwareRoundRobinPolicy(local_dc='datacenter1')
-  }
+.. code-block:: python
 
-  cluster = Cluster(**options)
\ No newline at end of file
+    cluster = Cluster(['10.1.1.3', '10.1.1.4', '10.1.1.5'])
+    session = cluster.connect('mykeyspace')
+
+
+You can always change a Sesssion's keyspace using :meth:`~.Session.set_keyspace` or
+by executing a ``USE <keyspace>`` query:
+
+.. code-block:: python
+
+    session.set_keyspace('users')
+    # or you can do this instead
+    session.execute('USE users')
+
+
+Executing Queries
+-----------------
+Now that we have a :class:`.Session` we can begin to execute queries. The most
+basic and natural way to execute a query is to use :meth:`~.Session.execute()`:
+
+.. code-block:: python
+
+    rows = session.execute('SELECT name, age, email FROM users')
+    for user_row in rows:
+        print user_row.name, user_row.age, user_row.email
+
+This will transparently pick a Cassandra node to execute the query against
+and handle any retries that are necessary if the operation fails.
+
+By default, each row in the result set will be a
+`namedtuple <http://docs.python.org/2/library/collections.html#collections.namedtuple>`_.
+Each row will have a matching attribute for each column defined in the schema,
+such as ``name``, ``age``, and so on.  You can also treat them as normal tuples
+by unpacking them or accessing fields by position:
+
+.. code-block:: python
+
+    rows = session.execute('SELECT name, age, email FROM users')
+    for (name, age, email) in rows:
+        print name, age, email
+
+.. code-block:: python
+
+    rows = session.execute('SELECT name, age, email FROM users')
+    names = [row[0] for row in rows]
+    ages = [row[1] for row in rows]
+    emails = [row[2] for row in rows]
+
+If you prefer another result format, such as a ``dict`` per row, you
+can change the :attr:`~.Session.row_factory` attribute.
+
+Passing Parameters to CQL Queries
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+When executing non-prepared statements, the driver supports two forms of
+parameter place-holders: positional and named.
+
+Positional parameters are used with a ``%s`` placeholder.  For example,
+when you execute:
+
+.. code-block:: python
+
+    session.execute(
+        """
+        INSERT INTO users (name, credits, user_id)
+        VALUES (%s, %s, %s)
+        """
+        ("John O'Reilly", 42, uuid.uuid1())
+    )
+
+It is translated to the following CQL query:
+
+.. code-block:: SQL
+
+    INSERT INTO users (name, credits, user_id)
+    VALUES ('John O''Reilly', 42, 2644bada-852c-11e3-89fb-e0b9a54a6d93)
+
+Note that you should use ``%s`` for all types of arguments, not just strings.
+For example, this would be **wrong**:
+
+.. code-block:: python
+
+    session.execute("INSERT INTO USERS (name, age) VALUES (%s, %d)", ("bob", 42))  # wrong
+
+Instead, use ``%s`` for the age placeholder.
+
+If you need to use a literal ``%`` character, use ``%%``.
+
+**Note**: you must always use a sequence for the second argument, even if you are
+only passing in a single variable:
+
+.. code-block:: python
+
+    session.execute("INSERT INTO foo (bar) VALUES (%s)", "blah")  # wrong
+    session.execute("INSERT INTO foo (bar) VALUES (%s)", ("blah"))  # wrong
+    session.execute("INSERT INTO foo (bar) VALUES (%s)", ("blah", ))  # right
+    session.execute("INSERT INTO foo (bar) VALUES (%s)", ["blah"])  # right
+
+
+Note that the second line is incorrect because in Python, single-element tuples
+require a comma.
+
+Named place-holders use the ``%(name)s`` form:
+
+.. code-block:: python
+
+    session.execute(
+        """
+        INSERT INTO users (name, credits, user_id, username)
+        VALUES (%(name)s, %(credits)s, %(user_id)s, %(name)s)
+        """
+        {'name': "John O'Reilly", 'credits': 42, 'user_id': uuid.uuid1()}
+    )
+
+Note that you can repeat placeholders with the same name, such as ``%(name)s``
+in the above example.
+
+Only data values should be supplied this way.  Other items, such as keyspaces,
+table names, and column names should be set ahead of time (typically using
+normal string formatting).
+
+Type Conversions
+^^^^^^^^^^^^^^^^
+For non-prepared statements, Python types are cast to CQL literals in the
+following way:

+    +--------------------+-------------------------+
+
+
+Asynchronous Queries
+^^^^^^^^^^^^^^^^^^^^
+The driver supports asynchronous query execution through
+:meth:`~.Session.execute_async()`.  Instead of waiting for the query to
+complete and returning rows directly, this method almost immediately
+returns a :class:`~.ResponseFuture` object.  There are two ways of
+getting the final result from this object.
+
+The first is by calling :meth:`~.ResponseFuture.result()` on it. If
+the query has not yet completed, this will block until it has and
+then return the result or raise an Exception if an error occurred.
+For example:
+
+.. code-block:: python
+
+    from cassandra import ReadTimeout
+
+    query = "SELECT * FROM users WHERE user_id=%s"
+    future = session.execute_async(query, [user_id])
+
+    # ... do some other work
+
+    try:
+        rows = future.result()
+        user = rows[0]
+        print user.name, user.age
+    except ReadTimeout:
+        log.exception("Query timed out:")
+
+This works well for executing many queries concurrently:
+
+.. code-block:: python
+
+    # build a list of futures
+    futures = []
+    query = "SELECT * FROM users WHERE user_id=%s"
+    for user_id in ids_to_fetch:
+        futures.append(session.execute_async(query, [user_id])
+
+    # wait for them to complete and use the results
+    for future in futures:
+        rows = future.result()
+        print rows[0].name
+
+Alternatively, instead of calling :meth:`~.ResponseFuture.result()`,
+you can attach callback and errback functions through the
+:meth:`~.ResponseFuture.add_callback()`,
+:meth:`~.ResponseFuture.add_errback()`, and
+:meth:`~.ResponseFuture.add_callbacks()`, methods.  If you have used
+Twisted Python before, this is designed to be a lightweight version of
+that:
+
+.. code-block:: python
+
+    def handle_success(rows):
+        user = rows[0]
+        try:
+            process_user(user.name, user.age, user.id)
+        except Exception:
+            log.error("Failed to process user %s", user.id)
+            # don't re-raise errors in the callback
+
+    def handle_error(exception):
+        log.error("Failed to fetch user info: %s", exception)
+
+
+    future = session.execute_async(query)
+    future.add_callbacks(handle_success, handle_error)
+
+There are a few important things to remember when working with callbacks:
+ * **Exceptions that are raised inside the callback functions will be logged and then ignored.**
+ * Your callback will be run on the event loop thread, so any long-running
+   operations will prevent other requests from being handled
+
+
+Setting a Consistency Level
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+The consistency level used for a query determines how many of the
+replicas of the data you are interacting with need to respond for
+the query to be considered a success.
+
+By default, :attr:`.ConsistencyLevel.ONE` will be used for all queries. To
+specify a different consistency level, you will need to wrap your queries
+in a :class:`~.SimpleStatement`:
+
+.. code-block:: python
+
+    from cassandra import ConsistencyLevel
+    from cassandra.query import SimpleStatement
+
+    query = SimpleStatement(
+        "INSERT INTO users (name, age) VALUES (%s, %s)",
+        consistency_level=ConsistencyLevel.QUORUM)
+    session.execute(query, ('John', 42))
+
+Prepared Statements
+-------------------
+Prepared statements are queries that are parsed by Cassandra and then saved
+for later use.  When the driver uses a prepared statement, it only needs to
+send the values of parameters to bind.  This lowers network traffic
+and CPU utilization within Cassandra because Cassandra does not have to
+re-parse the query each time.
+
+To prepare a query, use :meth:`.Session.prepare()`:
+
+.. code-block:: python
+
+    user_lookup_stmt = session.prepare("SELECT * FROM users WHERE user_id=?")
+
+    users = []
+    for user_id in user_ids_to_query:
+        user = session.execute(user_lookup_stmt, [user_id])
+        users.append(user)
+
+:meth:`~.Session.prepare()` returns a :class:`~.PreparedStatement` instance
+which can be used in place of :class:`~.SimpleStatement` instances or literal
+string queries.  It is automatically prepared against all nodes, and the driver
+handles re-preparing against new nodes and restarted nodes when necessary.
+
+Note that the placeholders for prepared statements are ``?`` characters.  This
+is different than for simple, non-prepared statements (although future versions
+of the driver may use the same placeholders for both).  Cassandra 2.0 added
+support for named placeholders; the 1.0 version of the driver does not support
+them, but the 2.0 version will.

+Installation
+============
+
+Supported Platforms
+-------------------
+Python 2.6 and 2.7 are supported.  Both CPython (the standard Python
+implementation) and `PyPy <http://pypy.org>`_ are supported and tested
+against.
+
+Linux, OSX, and Windows are supported.
+
+Support for Python 3 is planned.
+
+Installation through pip
+------------------------
+`pip <https://pypi.python.org/pypi/pip>`_ is the suggested tool for installing
+packages.  It will handle installing all python dependencies for the driver at
+the same time as the driver itself.  To install the driver::
+
+    pip install --pre cassandra-driver
+
+The ``--pre`` option is only needed while the python driver is still marked as
+a beta package.
+
+Manual Installation
+-------------------
+You can always install the driver directly from a source checkout or tarball.
+When installing manually, ensure the python dependencies are already
+installed: ``futures``, ``scales``, and ``blist``.
+
+Once the dependencies are installed, simply run::
+
+    python setup.py install
+
+(Optional) Non-python Dependencies
+----------------------------------
+The driver has several **optional** features that have non-Python dependencies.
+
+C Extensions
+^^^^^^^^^^^^
+By default, two C extensions are compiled: one that adds support
+for token-aware routing with the Murmur3Partitioner, and one that
+allows you to use libev for the event loop, which improves performance.
+
+When installing manually through setup.py, you can disable both with
+the ``--no-extensions`` option, or selectively disable one or the other
+with ``--no-murmur3`` and ``--no-libev``.
+
+To compile the extenions, ensure that GCC and the Python headers are available.
+
+On Ubuntu and Debian, this can be accomplished by running::
+
+    $ sudo apt-get install gcc python-dev
+
+On RedHat and RedHat-based systems like CentOS and Fedora::
+
+    $ sudo yum install gcc python-devel
+
+On OS X, homebrew installations of Python should provide the necessary headers.
+
+libev support
+^^^^^^^^^^^^^
+The driver currently uses Python's ``asyncore`` module for its default
+event loop.  For better performance, ``libev`` is also supported through
+a C extension.
+
+If you're on Linux, you should be able to install libev
+through a package manager.  For example, on Debian/Ubuntu::
+
+    $ sudo apt-get install libev4 libev-dev
+
+On RHEL/CentOS/Fedora::
+
+    $ sudo yum install libev libev-devel
+
+If you're on Mac OS X, you should be able to install libev
+through `Homebrew <http://brew.sh/>`_. For example, on Mac OS X::
+
+    $ brew install libev
+
+If successful, you should be able to build and install the extension
+(just using ``setup.py build`` or ``setup.py install``) and then use
+the libev event loop by doing the following:
+
+.. code-block:: python
+
+    >>> from cassandra.io.libevreactor import LibevConnection
+    >>> from cassandra.cluster import Cluster
+
+    >>> cluster = Cluster()
+    >>> cluster.connection_class = LibevConnection
+    >>> session = cluster.connect()
+
+Compression Support
+^^^^^^^^^^^^^^^^^^^
+Compression can optionally be used for communication between the driver and
+Cassandra.  There are currently two supported compression algorithms:
+snappy (in Cassandra 1.2+) and LZ4 (only in Cassandra 2.0+).  If either is
+available for the driver and Cassandra also supports it, it will
+be used automatically.
+
+For lz4 support::
+
+    $ pip install lz4
+
+For snappy support::
+
+    $ pip install python-snappy
+
+(If using a Debian Linux derivative such as Ubuntu, it may be easier to
+just run ``apt-get install python-snappy``.)

+Performance Notes
+=================
+The python driver for Cassandra offers several methods for executing queries.
+You can synchronously block for queries to complete using
+:meth:`.Session.execute()`, you can use a future-like interface through
+:meth:`.Session.execute_async()`, or you can attach a callback to the future
+with :meth:`.ResponseFuture.add_callback()`.  Each of these methods has
+different performance characteristics and behaves differently when
+multiple threads are used.
+
+Benchmark Notes
+---------------
+All benchmarks were executed using the
+`benchmark scripts <https://github.com/datastax/python-driver/tree/master/benchmarks>`_
+in the driver repository.  They were executed on a laptop with 16 GiB of RAM, an SSD,
+and a 2 GHz, four core CPU with hyperthreading.  The Cassandra cluster was a three
+node `ccm <https://github.com/pcmanus/ccm>`_ cluster running on the same laptop
+with version 1.2.13 of Cassandra. I suggest testing these benchmarks against your
+ own cluster when tuning the driver for optimal throughput or latency.
+
+The 1.0.0 version of the driver was used with all default settings.
+
+Each benchmark completes 100,000 small inserts. The replication factor for the
+ keyspace was three, so all nodes were replicas for the inserted rows.
+
+Synchronous Execution (`sync.py <https://github.com/datastax/python-driver/blob/master/benchmarks/sync.py>`_)
+-------------------------------------------------------------------------------------------------------------
+Although this is the simplest way to make queries, it has low throughput
+in single threaded environments.  This is basically what the benchmark
+is doing:
+
+.. code-block:: python
+
+    from cassandra.cluster import Cluster
+
+    cluster = Cluster([127.0.0.1, 127.0.0.2, 127.0.0.3])
+    session = cluster.connect()
+
+    for i in range(100000):
+        session.execute("INSERT INTO mykeyspace.mytable (key, b, c) VALUES (a, 'b', 'c')")
+
+.. code-block:: bash
+
+    ~/python-driver $ python benchmarks/sync.py -n 100000 --hosts=127.0.0.1,127.0.0.2,127.0.0.3 --libev-only --threads=1
+    Average throughput: 434.08/sec
+
+
+This technique does scale reasonably well as we add more threads:
+
+.. code-block:: bash
+
+    ~/python-driver $ python benchmarks/sync.py -n 100000 --hosts=127.0.0.1,127.0.0.2,127.0.0.3 --libev-only --threads=2
+    Average throughput: 830.49/sec
+    ~/python-driver $ python benchmarks/sync.py -n 100000 --hosts=127.0.0.1,127.0.0.2,127.0.0.3 --libev-only --threads=4
+    Average throughput: 1078.27/sec
+    ~/python-driver $ python benchmarks/sync.py -n 100000 --hosts=127.0.0.1,127.0.0.2,127.0.0.3 --libev-only --threads=8
+    Average throughput: 1275.20/sec
+    ~/python-driver $ python benchmarks/sync.py -n 100000 --hosts=127.0.0.1,127.0.0.2,127.0.0.3 --libev-only --threads=16
+    Average throughput: 1345.56/sec
+
+
+In my environment, throughput is maximized at about 20 threads.
+
+
+Batched Futures (`future_batches.py <https://github.com/datastax/python-driver/blob/master/benchmarks/future_batches.py>`_)
+---------------------------------------------------------------------------------------------------------------------------
+This is a simple way to work with futures for higher throughput.  Essentially,
+we start 120 queries asynchronously at the same time and then wait for them
+all to complete. We then repeat this process until all 100,000 operations
+have completed:
+
+.. code-block:: python
+
+    futures = Queue.Queue(maxsize=121)
+    for i in range(100000):
+        if i % 120 == 0:
+            # clear the existing queue
+            while True:
+                try:
+                    futures.get_nowait().result()
+                except Queue.Empty:
+                    break
+
+        future = session.execute_async(query)
+        futures.put_nowait(future)
+
+As expected, this improves throughput in a single-threaded environment:
+
+.. code-block:: bash
+
+    ~/python-driver $ python benchmarks/future_batches.py -n 100000 --hosts=127.0.0.1,127.0.0.2,127.0.0.3 --libev-only --threads=1
+    Average throughput: 3477.56/sec
+
+However, adding more threads may actually harm throughput:
+
+.. code-block:: bash
+

+
+
+Queued Futures (`future_full_pipeline.py <https://github.com/datastax/python-driver/blob/master/benchmarks/future_full_pipeline.py>`_)
+--------------------------------------------------------------------------------------------------------------------------------------
+This pattern is similar to batched futures.  The main difference is that
+every time we put a future on the queue, we pull the oldest future out
+and wait for it to complete:
+
+.. code-block:: python
+
+        futures = Queue.Queue(maxsize=121)
+        for i in range(100000):
+            if i >= 120:
+                old_future = futures.get_nowait()
+                old_future.result()
+
+            future = session.execute_async(query)
+            futures.put_nowait(future)
+
+This gets slightly better throughput than the Batched Futures pattern:
+
+.. code-block:: bash
+
+    ~/python-driver $ python benchmarks/future_full_pipeline.py -n 100000 --hosts=127.0.0.1,127.0.0.2,127.0.0.3 --libev-only --threads=1
+    Average throughput: 3635.76/sec
+
+But this has the same throughput issues when multiple threads are used:
+
+.. code-block:: bash
+
+    ~/python-driver $ python benchmarks/future_full_pipeline.py -n 100000 --hosts=127.0.0.1,127.0.0.2,127.0.0.3 --libev-only --threads=2
+    Average throughput: 2213.62/sec
+    ~/python-driver $ python benchmarks/future_full_pipeline.py -n 100000 --hosts=127.0.0.1,127.0.0.2,127.0.0.3 --libev-only --threads=4
+    Average throughput: 2707.62/sec
+    ~/python-driver $ python benchmarks/future_full_pipeline.py -n 100000 --hosts=127.0.0.1,127.0.0.2,127.0.0.3 --libev-only --threads=8
+    Average throughput: 2462.42/sec
+
+Unthrottled Futures (`future_full_throttle.py <https://github.com/datastax/python-driver/blob/master/benchmarks/future_full_throttle.py>`_)
+-------------------------------------------------------------------------------------------------------------------------------------------
+What happens if we don't throttle our async requests at all?
+
+.. code-block:: python
+
+    futures = []
+    for i in range(100000):
+        future = session.execute_async(query)
+        futures.append(future)
+
+    for future in futures:
+        future.result()
+
+Throughput is about the same as the previous pattern, but a lot of memory will
+be consumed by the list of Futures:
+
+.. code-block:: bash
+
+    ~/python-driver $ python benchmarks/future_full_throttle.py -n 100000 --hosts=127.0.0.1,127.0.0.2,127.0.0.3 --libev-only --threads=1

+    Average throughput: 2389.61/sec
+    ~/python-driver $ python benchmarks/future_full_throttle.py -n 100000 --hosts=127.0.0.1,127.0.0.2,127.0.0.3 --libev-only --threads=4
+    Average throughput: 2371.75/sec
+    ~/python-driver $ python benchmarks/future_full_throttle.py -n 100000 --hosts=127.0.0.1,127.0.0.2,127.0.0.3 --libev-only --threads=8
+    Average throughput: 2165.29/sec
+
+Callback Chaining (`callbacks_full_pipeline.py <https://github.com/datastax/python-driver/blob/master/benchmarks/callbacks_full_pipeline.py>`_)
+-----------------------------------------------------------------------------------------------------------------------------------------------
+This pattern is very different from the previous patterns.  Here we're taking
+advantage of the :meth:`.ResponseFuture.add_callback()` function to start
+another request as soon as one finishes.  Futhermore, we're starting 120
+of these callback chains, so we've always got about 120 operations in
+flight at any time:
+
+.. code-block:: python
+
+    from itertools import count
+    from threading import Event
+
+    num_started = count()
+    num_finished = count()
+    initial = object()
+    finished_event = Event()
+
+    def handle_error(exc):
+        log.error("Error on insert: %r", exc)
+
+    def insert_next(previous_result):
+        current_num = num_started.next()
+
+        if previous_result is not initial:
+            num = next(num_finished)
+            if num >= 100000:
+                finished_event.set()
+
+        if current_num <= 100000:
+            future = session.execute_async(query)
+            future.add_callbacks(insert_next, handle_error)
+
+    for i in range(120):
+        insert_next(initial)
+
+    finished_event.wait()
+
+This is a more complex pattern, but the throughput is excellent:
+
+.. code-block:: bash
+
+    ~/python-driver $ python benchmarks/callback_full_pipeline.py -n 100000 --hosts=127.0.0.1,127.0.0.2,127.0.0.3 --libev-only --threads=1
+    Average throughput: 7647.30/sec
+
+Part of the reason why performance is so good is that everything is running on
+single thread: the internal event loop thread that powers the driver.  The
+downside to this is that adding more threads doesn't improve anything:
+
+.. code-block:: bash
+
+    ~/python-driver $ python benchmarks/callback_full_pipeline.py -n 100000 --hosts=127.0.0.1,127.0.0.2,127.0.0.3 --libev-only --threads=2
+    Average throughput: 7704.58/sec
+
+
+What happens if we have more than 120 callback chains running?
+
+With 250 chains:
+
+.. code-block:: bash
+
+    ~/python-driver $ python benchmarks/callback_full_pipeline.py -n 100000 --hosts=127.0.0.1,127.0.0.2,127.0.0.3 --libev-only --threads=1
+    Average throughput: 7794.22/sec
+
+Things look pretty good with 250 chains.  If we try 500 chains, we start to max out
+all of the connections in the connection pools.  The problem is that the current
+version of the driver isn't very good at throttling these callback chains, so
+a lot of time gets spent waiting for new connections and performance drops
+dramatically:
+
+.. code-block:: bash
+
+    ~/python-driver $ python benchmarks/callback_full_pipeline.py -n 100000 --hosts=127.0.0.1,127.0.0.2,127.0.0.3 --libev-only --threads=1
+    Average throughput: 679.61/sec
+
+Until this is improved, you should limit the number of callback chains you run.
+
+PyPy
+----
+Almost all of these patterns become CPU-bound pretty quickly with CPython, the
+normal implementation of python. `PyPy <http://pypy.org>`_ is an alternative
+implementation of Python (written in Python) which uses a JIT compiler to
+reduce CPU consumption.  This leads to a huge improvement in the driver
+performance:
+
+.. code-block:: bash
+
+    ~/python-driver $ pypy benchmarks/callback_full_pipeline.py -n 500000 --hosts=127.0.0.1,127.0.0.2,127.0.0.3 --asyncore-only --threads=1
+    Average throughput: 18782.00/sec
+
+Eventually the driver may add C extensions to reduce CPU consumption, which
+would probably narrow the gap between the performance of CPython and PyPy.
+
+multiprocessing
+---------------
+All of the patterns here may be used over multiple processes using the
+`multiprocessing <http://docs.python.org/2/library/multiprocessing.html>`_
+module.  Multiple processes will scale significantly better than multiple
+threads will, so if high throughput is your goal, consider this option.
+
+Just be sure to **never share any :class:`~.Cluster`, :class:`~.Session`,
+or :class:`~.ResponseFuture` objects across multiple processes**. These
+objects should all be created after forking the process, not before.

-**Warning**
-
-This driver is currently under heavy development, so the API and layout of
-packages, modules, classes, and functions are subject to change.  There may
-also be serious bugs, so usage in a production environment is *not*
-recommended at this time.
-

-
-Features to be Added
---------------------
-* C extension for encoding/decoding messages
-* Twisted, gevent support
-* Python 3 support
-* IPv6 Support
-
 Installation
 ------------
-If you would like to use the optional C extensions, please follow
-the instructions in the section below before installing the driver.
-
 Installation through pip is recommended::
 
-    $ pip install cassandra-driver --pre
-
-If you want to install manually, you can instead do::
-
-    $ pip install futures scales blist # install dependencies
-    $ python setup.py install
-
-C Extensions
-^^^^^^^^^^^^
-By default, two C extensions are compiled: one that adds support
-for token-aware routing with the Murmur3Partitioner, and one that
-allows you to use libev for the event loop, which improves performance.
-
-When running setup.py, you can disable both with the ``--no-extensions``
-option, or selectively disable one or the other with ``--no-murmur3`` and
-``--no-libev``.
-
-To compile the extenions, ensure that GCC and the Python headers are available.
-
-On Ubuntu and Debian, this can be accomplished by running::
-
-    $ sudo apt-get install build-essential python-dev
-
-On RedHat and RedHat-based systems like CentOS and Fedora::
+    $ pip install cassandra-driver
 
-    $ sudo yum install gcc python-devel
+For more complete installation instructions, see the
+`installation guide <http://datastax.github.io/python-driver/installation.html>`_.
 
-On OS X, homebrew installations of Python should provide the necessary headers.
+Documentation
+-------------
+All documentation for the python driver, including installation details, API documentation,
+and a Getting Started guide, can be found `here <http://datastax.github.io/python-driver/index.html>`_.
 
-libev support
-^^^^^^^^^^^^^
-The driver currently uses Python's ``asyncore`` module for its default
-event loop.  For better performance, ``libev`` is also supported through
-a C extension.
+Reporting Problems
+------------------
+Please report any bugs and make any feature requests on the
+`JIRA <https://datastax-oss.atlassian.net/browse/PYTHON>`_ issue tracker.
 
-If you're on Linux, you should be able to install libev
-through a package manager.  For example, on Debian/Ubuntu::
+If you would like to contribute, please feel free to open a pull request.
 
-    $ sudo apt-get install libev4 libev-dev
-
-On RHEL/CentOS/Fedora::
-
-    $ sudo yum install libev libev-devel
-
-If you're on Mac OS X, you should be able to install libev
-through `Homebrew <http://brew.sh/>`_. For example, on Mac OS X::
-
-    $ brew install libev
-
-If successful, you should be able to build and install the extension
-(just using ``setup.py build`` or ``setup.py install``) and then use
-the libev event loop by doing the following:
-
-.. code-block:: python
-
-    >>> from cassandra.io.libevreactor import LibevConnection
-    >>> from cassandra.cluster import Cluster
-
-    >>> cluster = Cluster()
-    >>> cluster.connection_class = LibevConnection
-    >>> session = cluster.connect()
-
-Compression Support
-^^^^^^^^^^^^^^^^^^^
-Compression can optionally be used for communication between the driver and
-Cassandra.  There are currently two supported compression algorithms:
-snappy (in Cassandra 1.2+) and LZ4 (only in Cassandra 2.0+).  If either is
-available for the driver and Cassandra also supports it, it will
-be used automatically.
-
-For lz4 support::
-
-    $ pip install lz4
-
-For snappy support::
+Getting Help
+------------
+Your two best options for getting help with the driver are the
+`mailing list <https://groups.google.com/a/lists.datastax.com/forum/#!forum/python-driver-user>`_
+and the IRC channel.
 
-    $ pip install python-snappy
+For IRC, use the #datastax-drivers channel on irc.freenode.net.  If you don't have an IRC client,
+you can use `freenode's web-based client <http://webchat.freenode.net/?channels=#datastax-drivers>`_.
 
-(If using a Debian Linux derivative such as Ubuntu, it may be easier to
-just run ``apt-get install python-snappy``.)

Subject: [PATCH 0814/4528] Fix UTF8Type serialization for already-encoded utf8

If your data is already utf-8 encoded by the time it reaches the UTF8Type.serialize() method, the encode() will fail, raising a UnicodeDecodeError.
Explicitly testing the type for Unicode before the .encode() should guarantee it doesn't fail, and in cases where it isn't Unicode, we simply test whether it's already a valid byte-encoded unicode string by attempting to decode it.
This shouldn't add any significant overhead for strings passed in as Unicode, will prevent unnecessary failures with already-encoded Unicode strings, and raise a UnicodeDecodeError otherwise.

Subject: [PATCH 0828/4528] Skip OPTIONS message if cql_version, compression
 not set

By default compression is enabled, so the OPTIONS message will typically
be sent. But, if cql_version was not set and either compression was
explicitly disabled or no compressors are locally supported, the driver
will skip the OPTIONS message.

Subject: [PATCH 0831/4528] Always close sockets when defuncting connections

Under certain error conditions, this could result in an FD leak for the
socket handles.  (In my testing, they seemed to eventually be GC'ed and
closed, but this behavior is probably not dependable.)

Fixes #80

+level on that:

 Compaction Options
-====================
+==================
 
     As of cqlengine 0.7 we've added support for specifying compaction options.  cqlengine will only use your compaction options if you have a strategy set.  When a table is synced, it will be altered to match the compaction options set on your table.  This means that if you are changing settings manually they will be changed back on resync.  Do not use the compaction settings of cqlengine if you want to manage your compaction settings manually.

Subject: [PATCH 0907/4528] Undo param passing for non-prepared statements

There are a couple of reasons this can't be supported at the moment.

The first, and most serious, is that the passed parameters must be in
their binary form, not a string representation.  For non-prepared
statements, the driver doesn't know what Cassandra types it's dealing
with, so the best it can do is map python types to string formatting
functions (see cql_encoders).  It can't tell if it should convert 123 to
the Int32Type binary representation or the IntegerType binary
representation.  (Likewise for FloatType and DoubleType.)

Second, Cassandra doesn't accept a map of parameter names to parameter
values, so even though there are named placeholders, the driver would
have to parse the query string to handle a dict of parameters.

Subject: [PATCH 0935/4528] Ingore SSL_ERROR_WANT_READ/WRITE errors

Before this change, the connection would be defuncted when the error
occurred.  Instead, these can safely be ignored and the recv() call
retried.

     Tables may use `LeveledCompactionStrategy` or `SizeTieredCompactionStrategy`.  Both options are available in the top level cqlengine module.  To reiterate, you will need to set your `__compaction__` option explicitly in order for cqlengine to handle any of your settings.

+        The serial consistency level is only used by conditional updates
+        (``INSERT``, ``UPDATE`` and ``DELETE`` with an ``IF`` condition).  For
+        those, the ``serial_consistency_level`` defines the consistency level of
+        the serial phase (or "paxos" phase) while the normal
+        :attr:`~.consistency_level` defines the consistency for the "learn" phase,
+        i.e. what type of reads will be guaranteed to see the update right away.
+        For example, if a conditional write has a :attr:`~.consistency_level` of
+        :attr:`~.ConsistencyLevel.QUORUM` (and is successful), then a
+        :attr:`~.ConsistencyLevel.QUORUM` read is guaranteed to see that write.
+        But if the regular :attr:`~.consistency_level` of that write is
+        :attr:`~.ConsistencyLevel.ANY`, then only a read with a
+        :attr`~.consistency_level` of :attr:`~.ConsistencyLevel.SERIAL` is
+        guaranteed to see it (even a read with consistency
+        :attr:`~.ConsistencyLevel.ALL` is not guaranteed to be enough).
+
+        The serial consistency can only be one of :attr:`~ConsistencyLevel.SERIAL`
+        or :attr:`~ConsistencyLevel.LOCAL_SERIAL`. While ``SERIAL`` guarantees full
+        linearizability (with other ``SERIAL`` updates), ``LOCAL_SERIAL`` only
+        guarantees it in the local data center.
+
+        The serial consistency level is ignored for any query that is not a
+        conditional update. Serial reads should use the regular
+        :attr:`consistency_level`.
+
+        Serial consistency levels may only be used against Cassandra 2.0+

 27, 33, pypy).

Have taken the approach of replacing methods at module load time (using if six.PY2). Much of this has been required where the assumption has been made that strings are not unicode, this of course is not true of Python 3

Subject: [PATCH 1012/4528] Fixes #97, error following 'DROP TABLE'.

which resulted in cluster conn being terminated. Resolved this with
checking if the key (the name of the dropped table) exists.

+Subject: don't use ez_setup
+
+Debian packages aren't supposed to download stuff while building, and
+since the version of setuptools in stable is less than the one ez_setup
+wants, and since some system python packages don't ship their .egg-info
+directories, it might try.
+
+It's ok though, we can rely on the Depends and Build-Depends for making
+sure python-setuptools and the various other deps are around at the right
+times.

+Paging Large Queries
+====================
+Cassandra 2.0+ offers support for automatic query paging.  Starting with
+version 2.0 of the driver, if :attr:`~.Cluster.protocol_version` is set to
+:const:`2` (it is by default), queries returning large result sets will be
+automatically paged.
+
+Controlling the Page Size
+-------------------------
+By default, :attr:`.Session.default_fetch_size` controls how many rows will
+be fetched per page.  This can be overridden per-query by setting
+:attr:`~.fetch_size` on a :class:`~.Statement`.  By default, each page
+will contain at most 5000 rows.
+
+Handling Paged Results
+----------------------
+Whenever the number of result rows for are query exceed the page size, an
+instance of :class:`~.PagedResult` will be returned instead of a normal
+list.  This class implements the iterator interface, so you can treat
+it like a normal iterator over rows::
+
+    from cassandra.query import SimpleStatement
+    query = "SELECT * FROM users"  # users contains 100 rows
+    statement = SimpleStatement(query, fetch_size=10)
+    for user_row in session.execute(statement):
+        process_user(user_row)
+
+Whenever there are no more rows in the current page, the next page will
+be fetched transparently.  However, note that it *is* possible for
+an :class:`Exception` to be raised while fetching the next page, just
+like you might see on a normal call to ``session.execute()``.
+
+If you use :meth:`.Session.execute_async()` along with,
+:meth:`.ResponseFuture.result()`, the first page will be fetched before
+:meth:`~.ResponseFuture.result()` returns, but latter pages will be
+transparently fetched synchronously while iterating the result.
+
+Handling Paged Results with Callbacks
+-------------------------------------
+If callbacks are attached to a query that returns a paged result,
+the callback will be called once per page with a normal list of rows.
+
+Use :attr:`.ResponseFuture.has_more_pages` and
+:meth:`.ResponseFuture.start_fetching_next_page()` to continue fetching
+pages.  For example::
+
+    class PagedResultHandler(object):
+
+        def __init__(self, future):
+            self.error = None
+            self.finished_event = Event()
+            self.future = future
+            self.future.add_callbacks(
+                callback=self.handle_page,
+                errback=self.handle_err)
+
+        def handle_page(self, rows):
+            for row in rows:
+                process_row(row)
+
+            if self.future.has_more_pages:
+                self.future.start_fetching_next_page()
+            else:
+                self.finished_event.set()
+
+        def handle_error(self, exc):
+            self.error = exc
+            self.finished_event.set()
+
+    future = session.execute_async("SELECT * FROM users")
+    handler = PagedResultHandler(future)
+    handler.finished_event.wait()
+    if handler.error:
+        raise handler.error

+    Executes a sequence of (statement, parameters) tuples concurrently.  Each
+    ``parameters`` item must be a sequence or :const:`None`.
+
+    A sequence of ``(success, result_or_exc)`` tuples is returned in the same
+    order that the statements were passed in.  If ``success`` if :const:`False`,
+    there was an error executing the statement, and ``result_or_exc`` will be
+    an :class:`Exception`.  If ``success`` is :const:`True`, ``result_or_exc``
+    will be the query result.
+
+    If `raise_on_first_error` is left as :const:`True`, execution will stop
+    after the first failed statement and the corresponding exception will be
+    raised.
+
+    The `concurrency` parameter controls how many statements will be executed
+    concurrently.  It is recommended that this be kept below the number of
+    core connections per host times the number of connected hosts (see
+    :meth:`.Cluster.set_core_connections_per_host`).  If that amount is exceeded,
+    the event loop thread may attempt to block on new connection creation,
+    substantially impacting throughput.

Subject: [PATCH 1053/4528] When creating a new connection use the same query

When a new control connection is made a table is queried multiple times before
the control connection is established. This patch combines the queries to that table
by using "preloaded" results. This seemed like a minimal way to make the change, but
might not necessarily be the best way. Let me know if you feel like a different approach
should be used.

@@ -274,6 +274,9 @@ Batch Queries
 
     cqlengine now supports batch queries using the BatchQuery class. Batch queries can be started and stopped manually, or within a context manager. To add queries to the batch object, you just need to precede the create/save/delete call with a call to batch, and pass in the batch object.
 
+Batch Query General Use Pattern
+-------------------------------
+
     You can only create, update, and delete rows with a batch query, attempting to read rows out of the database with a batch query will fail.
 
     .. code-block:: python
@@ -324,6 +327,96 @@ Batch Queries
 
     If an exception is thrown somewhere in the block, any statements that have been added to the batch will still be executed.  This is useful for some logging situations.
 
+Batch Query Execution Callbacks
+-------------------------------
+
+    In order to allow secondary tasks to be chained to the end of batch, BatchQuery instances allow callbacks to be
+    registered with the batch, to be executed immediately after the batch executes.
+
+    Let's say an iterative action over a group of records needs to be followed up by a "maintenance" task like "Update
+    count of children on parent model."
+    If your were to kick off that task following manipulation on each child, while the batch is not executed, the reads
+    the maintenance task would do would operate on old data since the batch is not yet commited.
+    (You also risk kicking off too many of the same tasks, while only one is needed at the end of the batch.)
+
+    The callbacks attached to a given batch instance are executed only if the batch executes. If the batch is used as a
+    context manager and an exception bubbles up, the queued up callbacks will not be run.
+
+    The callback should be a callable object that accepts at least one (positional) argument - instance of the batch object.
+
+    .. code-block:: python
+
+        def example_callback_handler(batch, *args, **kwargs):
+            pass
+
+    Multiple callbacks can be attached to same BatchQuery instance both, at the point of instantiation and later
+    directly to the batch object instance.
+
+    The callbacks collection is implemented as a ``set``, which naturally deduplicates the callback handlers:
+
+    .. code-block:: python
+
+        # let's add a few of the same callbacks at init
+        batch = BatchQuery(callbacks=([
+            example_callback_handler,
+            example_callback_handler
+        ])
+
+        # and one more time same callback now using the collection API on the batch instance
+        batch.callbacks.add(example_callback_handler)
+
+        assert len(batch.callbacks) == 1
+        assert batch.callbacks == {example_callback_handler}
+
+        # this, of course, also means that if you remove a callback,
+        # you negate "all additions" of that callback
+        batch.callbacks.remove(example_callback_handler)
+
+        assert len(batch.callbacks) == 0
+
+    In order to benefit from the natural deduplication of the callback handlers it is allowed to pass in tuples of
+    callback and its positional arguments.
+    This allows one to pre-package additional call arguments for the callable without the need to wrap the callable and
+    args into a closure or ``functools.partial``.
+
+    .. code-block:: python
+
+        batch = BatchQuery(callbacks=([
+            (example_callback_handler, 'some', 'args'),
+            (example_callback_handler, 'some', 'args'),
+            (example_callback_handler, 'some other', 'args'),
+        ])
+
+        batch.callbacks.add((example_callback_handler, 'some other', 'args'))
+
+        assert len(batch.callbacks) == 2
+        assert batch.callbacks == {
+            (example_callback_handler, 'some', 'args'),
+            (example_callback_handler, 'some other', 'args')
+        }
+
+    Note that the tuple callback object format prevents the possibily of essentially same callback firing multiple times,
+    which might happen if you package same callback and arguments several times with ``functools.partial``, which returns a new callable with each call.
+
+    Arguments packaged into callbacks communicated as tuples are passed to callback handler **after** the ``batch`` argument.
+
+    .. code-block:: python
+
+        call_args = []
+
+        def callback_handler(batch, *args, **kwargs):
+            call_args.append([batch] + list(args))
+
+        batch = BatchQuery(callbacks=([(callback_handler, 'some', 'args')])
+
+        batch.execute()
+
+        assert call_args == [[batch, 'some', 'args']]
+
+
+    Failure in any of the callbacks does not affect the batch's execution, as the callbacks are started after the execution
+    of the batch is complete and no effort to "roll it back" is made.
+

+Table Properties
+================
+
+    Each table can have its own set of configuration options.
+    These can be specified on a model with the following attributes:
+
+    .. attribute:: Model.__bloom_filter_fp_chance
+
+    .. attribute:: Model.__caching__
+
+    .. attribute:: Model.__comment__
+
+    .. attribute:: Model.__dclocal_read_repair_chance__
+
+    .. attribute:: Model.__default_time_to_live__
+
+    .. attribute:: Model.__gc_grace_seconds__
+
+    .. attribute:: Model.__index_interval__
+
+    .. attribute:: Model.__memtable_flush_period_in_ms__
+
+    .. attribute:: Model.__populate_io_cache_on_flush__
+
+    .. attribute:: Model.__read_repair_chance__
+
+    .. attribute:: Model.__replicate_on_write__
+
+    Example:
+
+    .. code-block:: python
+
+        from cqlengine import ROWS_ONLY, columns
+        from cqlengine.models import Model
+
+        class User(Model):
+            __caching__ = ROWS_ONLY  # cache only rows instead of keys only by default
+            __gc_grace_seconds__ = 86400  # 1 day instead of the default 10 days
+
+            user_id = columns.UUID(primary_key=True)
+            name = columns.Text()
+
+    Will produce the following CQL statement:
+
+    .. code-block:: sql
+
+        CREATE TABLE cqlengine.user (
+            user_id uuid,
+            name text,
+            PRIMARY KEY (user_id)
+        ) WITH caching = 'rows_only'
+           AND gc_grace_seconds = 86400;
+
+    See the `list of supported table properties for more information
+    <http://www.datastax.com/documentation/cql/3.1/cql/cql_reference/tabProp.html>`_.

 Compaction Options

@@ -311,6 +368,7 @@ Compaction Options
 
     Tables may use `LeveledCompactionStrategy` or `SizeTieredCompactionStrategy`.  Both options are available in the top level cqlengine module.  To reiterate, you will need to set your `__compaction__` option explicitly in order for cqlengine to handle any of your settings.

Subject: [PATCH 1156/4528] Fix duplicate node-up handling

a22f80b8 introduced a bug where multiple UP notifications
could result in multiple reconnectors being started. It was also
possible for the executor threads to become deadlocked waiting on a
condition that would never be set, which meant that future down and up
node handling would never be executed.

Subject: [PATCH 1228/4528] Fix race condition during connect().

For https://datastax-oss.atlassian.net/browse/PYTHON-68

On python3, we occasionally see connection failures because the socket
is closed before the connect() is attempted. This is caused by the
asyncore event loop thread closing the socket prematurely. I suspect
this bug exists on python2 as well, but happens more often on python3
because of its more responsive thread scheduler. This patch causes the
the socket to be watched by the event loop only after the connect()
completes successfully.

+Security
+========
+The two main security components you will use with the
+Python driver are Authentication and SSL.
+
+Authentication
+--------------
+Versions 2.0 and higher of the driver support a SASL-based
+authentication mechanism when :attr:`~.Cluster.protocol_version`
+is set to 2 or higher.  To use this authentication, set
+:attr:`~.Cluster.auth_provider` to an instance of a subclass
+of :class:`~cassandra.auth.AuthProvider`.  When working
+with Cassandra's ``PasswordAuthenticator``, you can use
+the :class:`~cassandra.auth.PlainTextAuthProvider` class.
+
+For example, suppose Cassandra is setup with its default
+'cassandra' user with a password of 'cassandra':
+
+.. code-block:: python
+
+    from cassandra.cluster import Cluster
+    from cassandra.auth import PlainTextAuthProvider
+
+    auth_provider = PlainTextAuthProvider(username='cassandra', password='cassandra')
+    cluster = Cluster(auth_provider=auth_provider, protocol_version=2)
+
+
+When working with version 2 or higher of the driver, the protocol
+version is set to 2 by default, but we've included it in the example
+to be explicit.
+
+Custom Authenticators
+^^^^^^^^^^^^^^^^^^^^^
+If you're using something other than Cassandra's ``PasswordAuthenticator``,
+you may need to create your own subclasses of :class:`~.AuthProvider` and
+:class:`~.Authenticator`.  You can use :class:`~.PlainTextAuthProvider`
+and :class:`~.PlainTextAuthenticator` as example implementations.
+
+Protocol v1 Authentication
+^^^^^^^^^^^^^^^^^^^^^^^^^^
+When working with Cassandra 1.2 (or a higher version with
+:attr:`~.Cluster.protocol_version` set to ``1``), you will not pass in
+an :class:`~.AuthProvider` instance.  Instead, you should pass a dict
+of credentials with a ``username`` and ``password`` key:
+
+.. code-block:: python
+
+    from cassandra.cluster import Cluster
+
+    credentials = {'username': 'joe', 'password': '1234'}
+    cluster = Cluster(auth_provider=credentials, protocol_version=1)
+
+SSL
+---
+To enable SSL you will need to set :attr:`.Cluster.ssl_options` to a
+dict of options.  These will be passed as kwargs to ``ssl.wrap_socket()``
+when new sockets are created.  This should be used when client encryption
+is enabled in Cassandra.
+
+By default, a ``ca_certs`` value should be supplied (the value should be
+a string pointing to the location of the CA certs file), and you probably
+want to specify ``ssl_version`` as ``ssl.PROTOCOL_TLSv1`` to match
+Cassandra's default protocol.
+
+For example:
+
+.. code-block:: python
+
+    from cassandra.cluster import Cluster
+    from ssl import PROTOCOL_TLSv1
+
+    ssl_opts = {'ca_certs': '/path/to/my/ca.certs',
+                'ssl_version': PROTOCOL_TLSv1}
+    cluster = Cluster(ssl_options=ssl_opts)
+
+For further reading, Andrew Mussey has published a thorough guide on
+`Using SSL with the DataStax Python driver <http://blog.amussey.com/post/64036730812/cassandra-2-0-client-server-ssl-with-datastax-python>`_.

+Upgrading
+=========
+
+Upgrading to 2.0 from 1.x
+-------------------------
+Version 2.0 of the DataStax python driver for Apache Cassandra
+includes some notable improvements over version 1.x.  This version
+of the driver supports Cassandra 1.2, 2.0, and 2.1.  However, not
+all features may be used with Cassandra 1.2, and some new features
+in 2.1 are not yet supported.
+
+Using the v2 Native Protocol
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+By default, the driver will attempt to use version 2 of Cassandra's
+native protocol.  When working with Cassandra 1.2, you will need to
+explicitly set the :attr:`~.Cluster.protocol_version` to 1:
+
+.. code-block:: python
+
+    from cassandra.cluster import Cluster
+
+    cluster = Cluster(protocol_version=1)
+
+Automatic Query Paging
+^^^^^^^^^^^^^^^^^^^^^^
+Version 2 of the native protocol adds support for automatic query
+paging, which can make dealing with large result sets much simpler.
+
+See :ref:`query-paging` for full details.
+
+Protocol-Level Batch Statements
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+With version 1 of the native protocol, batching of statements required
+using a `BATCH cql query <http://cassandra.apache.org/doc/cql3/CQL.html#batchStmt>`_.
+With version 2 of the native protocol, you can now batch statements at
+the protocol level. This allows you to use many different prepared
+statements within a single batch.
+
+See :class:`~.query.BatchStatement` for details and usage examples.
+
+SASL-based Authentication
+^^^^^^^^^^^^^^^^^^^^^^^^^
+Also new in version 2 of the native protocol is SASL-based authentication.
+See the section on :ref:`security` for details and examples.
+
+Lightweight Transactions
+^^^^^^^^^^^^^^^^^^^^^^^^
+`Lightweight transactions <http://www.datastax.com/dev/blog/lightweight-transactions-in-cassandra-2-0>`_ are another new feature.  To use lightweight transactions, add ``IF`` clauses
+to your CQL queries and set the :attr:`~.Statement.serial_consistency_level`
+on your statements.
+
+Deprecations
+^^^^^^^^^^^^
+The following functions have moved from ``cassandra.decoder`` to ``cassandra.query``.
+The original functions have been left in place with a :exc:`DeprecationWarning` for
+now:
+
+* :attr:`cassandra.decoder.tuple_factory` has moved to
+  :attr:`cassandra.query.tuple_factory`
+* :attr:`cassandra.decoder.named_tuple_factory` has moved to
+  :attr:`cassandra.query.named_tuple_factory
+* :attr:`cassandra.decoder.dict_factory` has moved to
+  :attr:`cassandra.query.dict_factory`
+* :attr:`cassandra.decoder.ordered_dict_factory` has moved to
+  :attr:`cassandra.query.ordered_dict_factory`
+
+Dependency Changes
+^^^^^^^^^^^^^^^^^^
+The following dependencies have officially been made optional:
+
+* ``scales``
+* ``blist``
+
+And one new dependency has been added (to enable Python 3 support):
+
+* ``six``

Subject: [PATCH 1301/4528] Replace six.BytesIO with io.BytesIO for speed-up

On python 2.6 and 2.7, six.BytesIO maps to StringIO, which is slow:

https://github.com/kelp404/six/blob/master/six.py#L478

Python 2.6 and 2.7 provide the io module (for compatability with
the Python 3 io module), which defines a faster BytesIO implementation.
cProfile reveals a significant speedup when using the io module. Using
six.BytesIO:

   ncalls  tottime  percall  cumtime  percall filename:lineno(function)
  ...
  2277792    9.736    0.000   13.088    0.000 /usr/lib64/python2.6/StringIO.py:208(write)

However with io.BytesIO:

  2277792    0.920    0.000    0.920    0.000 {method 'write' of '_bytesio._BytesIO' objects}

This will break on Python 2.5, but I think that's ok.

     There is a special QuerySet's method ``.values_list()`` - when called, QuerySet returns lists of values instead of model instances. It may significantly speedup things with lower memory footprint for large responses.

 0.15 Upgrade to use Datastax Native Driver
 
-Calls to execute should no longer use named placeholders.
 We no longer raise cqlengine based OperationalError when connection fails.  Now using the exception thrown in the native driver.
 
 If you're calling setup() with the old thrift port in place, you will get connection errors.  Either remove it (the default native port is assumed) or change to the default native port, 9042.
+
+The cqlengine connection pool has been removed.  Connections are now managed by the native driver.  This should drastically reduce the socket overhead as the native driver can multiplex queries.

 =====
 In Progress
 
+This release adds support for Cassandra 2.1 features, including version
+3 of the native protocol.
+
 Features
 --------
+* When using the v3 protocol, only one connection is opened per-host, and
+  throughput is improved due to reduced pooling overhead and lock contention.
+* Support for user-defined types (Cassandra 2.1+)
+* Support for tuple type in (limited usage Cassandra 2.0.9, full usage
+  in Cassandra 2.1)
+* Protocol-level client-side timestamps (see Session.use_client_timestamp)
+* Overridable type encoding for non-prepared statements (see Session.encoders)
+* Configurable serial consistency levels for batch statements
 * Use io.BytesIO for reduced CPU consumption (github #143)
 * Support Twisted as a reactor. Note that a Twisted-compatible
   API is not exposed (so no Deferreds), this is just a reactor

 Frequently Asked Questions
 ==========================
 
-Q: Why does calling my Model(field=blah, field2=blah2) not work?
+Q: Why don't updates work correctly on models instantiated as Model(field=blah, field2=blah2)?
 -------------------------------------------------------------------
 
-A: The __init__() of a model is used by cqlengine internally.  If you want to create a new row in the database, use create().
+A: The recommended way to create new rows is with the models .create method. The values passed into a model's init method are interpreted by the model as the values as they were read from a row. This allows the model to "know" which rows have changed since the row was read out of cassandra, and create suitable update statements.

Subject: [PATCH 1552/4528] Handle custom encoders in nested data types

The root of the problem was that nested data types would use the default
encoders for subitems.  When the encoders were customized, they would
not be used for those nested items.

This fix moves the encoder functions into a class so that collections,
tuples, and UDTs will use the customized mapping when encoding subitems.

Fixes PYTHON-100.

 Upgrading
 =========
 
+.. toctree::
+   :maxdepth: 1
+
+Upgrading to 2.1 from 2.0
+-------------------------
+Version 2.1 of the Datastax python driver for Apache Cassandra
+adds support for Cassandra 2.1 and version 3 of the native protocol.
+
+Cassandra 1.2, 2.0, and 2.1 are all supported.  However, 1.2 only
+supports protocol version 1, and 2.0 only supports versions 1 and
+2, so some features may not be available.
+
+Using the v3 Native Protocol
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+By default, the driver will attempt to use version 2 of the
+native protocol.  To use version 3, you must explicitly
+set the :attr:`~.Cluster.protocol_version`:
+
+.. code-block:: python
+
+    from cassandra.cluster import Cluster
+
+    cluster = Cluster(protocol_version=3)
+
+Note that protocol version 3 is only supported by Cassandra 2.1+.
+
+In future releases, the driver may default to using protocol version
+3.
+
+Working with User-Defined Types
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Cassandra 2.1 introduced the ability to define new types::
+
+    USE KEYSPACE mykeyspace;
+
+    CREATE TYPE address (street text, city text, zip int);
+
+The driver generally expects you to use instances of a specific
+class to represent column values of this type.  You can let the
+driver know what class to use with :meth:`.Cluster.register_user_type`:
+
+.. code-block:: python
+
+    cluster = Cluster()
+
+    class Address(object):
+
+        def __init__(self, street, city, zipcode):
+            self.street = street
+            self.city = text
+            self.zipcode = zipcode
+
+    cluster.register_user_type('mykeyspace', 'address', Address)
+
+When inserting data for ``address`` columns, you should pass in
+instances of ``Address``.  When querying data, ``address`` column
+values will be instances of ``Address``.
+
+If no class is registered for a user-defined type, query results
+will use a ``namedtuple`` class and data may only be inserted
+though prepared statements.
+
+Customizing Encoders for Non-prepared Statements
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Starting with version 2.1 of the driver, it is possible to customize
+how python types are converted to CQL literals when working with
+non-prepared statements.  This is done on a per-:class:`~.Session`
+basis through :attr:`.Session.encoder`:
+
+.. code-block:: python
+
+    cluster = Cluster()
+    session = cluster.connect()
+    session.encoder.mapping[tuple] = session.encoder.cql_encode_tuple
+
+See :ref:`type-conversions` for the table of default CQL literal conversions.
+
+Using Client-Side Protocol-Level Timestamps
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+With version 3 of the native protocol, timestamps may be supplied by the
+client at the protocol level.  (Normally, if they are not specified within
+the CQL query itself, a timestamp is generated server-side.)
+
+When :attr:`~.Cluster.protocol_version` is set to 3 or higher, the driver
+will automatically use client-side timestamps with microsecond precision
+unless :attr:`.Session.use_client_timestamp` is changed to :const:`False`.
+If a timestamp is specified within the CQL query, it will override the
+timestamp generated by the driver.
+

+
+User Defined Types
+==================
+Cassandra 2.1 introduced user-defined types (UDTs).  You can create a
+new type through ``CREATE TYPE`` statements in CQL::
+
+    CREATE TYPE address (street text, zip int);
+
+Version 2.1 of the python driver adds support for user-defined types.
+
+Registering a Class to Map to a UDT
+-----------------------------------
+You can tell the python driver to return columns of a specific UDT as
+instances of a class by registering them with your :class:`~.Cluster`
+instance through :meth:`.Cluster.register_user_type`:
+
+.. code-block:: python
+
+    cluster = Cluster(protocol_version=3)
+    session = cluster.connect()
+    session.set_keyspace('mykeyspace')
+    session.execute("CREATE TYPE address (street text, zipcode int)")
+    session.execute("CREATE TABLE users (id int PRIMARY KEY, location address)")
+
+    # create a class to map to the "address" UDT
+    class Address(object):
+
+        def __init__(self, street, zipcode):
+            self.street = street
+            self.zipcode = zipcode
+
+    cluster.register_user_type('mykeyspace', 'address', Address)
+
+    # insert a row using an instance of Address
+    session.execute("INSERT INTO users (id, location) VALUES (%s, %s)",
+                    (0, Address("123 Main St.", 78723)))
+
+    # results will include Address instances
+    results = session.execute("SELECT * FROM users")
+    row = results[0]
+    print row.id, row.location.street, row.location.zipcode
+
+Using UDTs Without Registering Them
+-----------------------------------
+Although it is recommended to register your types with
+:meth:`.Cluster.register_user_type`, the driver gives you some options
+for working with unregistered UDTS.
+
+When you use prepared statements, the driver knows what data types to
+expect for each placeholder.  This allows you to pass any object you
+want for a UDT, as long as it has attributes that match the field names
+for the UDT:
+
+.. code-block:: python
+
+    cluster = Cluster(protocol_version=3)
+    session = cluster.connect()
+    session.set_keyspace('mykeyspace')
+    session.execute("CREATE TYPE address (street text, zipcode int)")
+    session.execute("CREATE TABLE users (id int PRIMARY KEY, location address)")
+
+    class Foo(object):
+
+        def __init__(self, street, zipcode, otherstuff):
+            self.street = street
+            self.zipcode = zipcode
+            self.otherstuff = otherstuff
+
+    insert_statement = session.prepare("INSERT INTO users (id, location) VALUES (?, ?)")
+
+    # since we're using a prepared statement, we don't *have* to register
+    # a class to map to the UDT to insert data.  The object just needs to have
+    # "street" and "zipcode" attributes (which Foo does):
+    session.execute(insert_statement, [0, Foo("123 Main St.", 78723, "some other stuff")]
+
+    # when we query data, UDT columns that don't have a class registered
+    # will be returned as namedtuples:
+    results = session.execute("SELECT * FROM users")
+    first_row = results[0]
+    address = first_row.address
+    print address  # prints "Address(street='123 Main St.', zipcode=78723)"
+    street = address.street
+    zipcode = address.street
+
+As shown in the code example, inserting data for UDT columns without registering
+a class works fine for prepared statements.  However, **you must register a
+class to insert UDT columns with unprepared statements**.  You can still query
+UDT columns without registered classes using unprepared statements, they will
+simply return ``namedtuple`` instances (just like prepared statements do).

 Q: Why don't updates work correctly on models instantiated as Model(field=blah, field2=blah2)?
 -------------------------------------------------------------------
 
-A: The recommended way to create new rows is with the models .create method. The values passed into a model's init method are interpreted by the model as the values as they were read from a row. This allows the model to "know" which rows have changed since the row was read out of cassandra, and create suitable update statements.

+A: The recommended way to create new rows is with the models .create method. The values passed into a model's init method are interpreted by the model as the values as they were read from a row. This allows the model to "know" which rows have changed since the row was read out of cassandra, and create suitable update statements.
+
+Q: How to preserve ordering in batch query?
+-------------------------------------------
+
+A: Statement Ordering is not supported by CQL3 batches. Therefore,
+once cassandra needs resolving conflict(Updating the same column in one batch),
+The algorithm below would be used.
+
+ * If timestamps are different, pick the column with the largest timestamp (the value being a regular column or a tombstone)
+ * If timestamps are the same, and one of the columns in a tombstone ('null') - pick the tombstone
+ * If timestamps are the same, and none of the columns are tombstones, pick the column with the largest value
+
+Below is an example to show this scenario.
+
+.. code-block:: python
+
+    class MyMode(Model):
+        id    = columns.Integer(primary_key=True)
+        count = columns.Integer()
+        text  = columns.Text()
+
+    with BatchQuery() as b:
+       MyModel.batch(b).create(id=1, count=2, text='123') 
+       MyModel.batch(b).create(id=1, count=3, text='111')
+
+    assert MyModel.objects(id=1).first().count == 3
+    assert MyModel.objects(id=1).first().text  == '123'
+
+The largest value of count is 3, and the largest value of text would be '123'.
+
+The workaround is applying timestamp to each statement, then Cassandra would
+resolve to the statement with the lastest timestamp.
+
+.. code-block:: python
+
+    with BatchQuery() as b:
+        MyModel.timestamp(datetime.now()).batch(b).create(id=1, count=2, text='123')
+        MyModel.timestamp(datetime.now()).batch(b).create(id=1, count=3, text='111')
+
+    assert MyModel.objects(id=1).first().count == 3
+    assert MyModel.objects(id=1).first().text  == '111'

Subject: [PATCH 1711/4528] Fix multiple bugs related to control connection
 timeout and schema refresh.

1. The Cluster's class-level 'control_connection_timeout' variable was never used
2. ControlConnection.wait_for_schema_agreement() ignored the timeout passed from Cluster and always used hard-coded 2.0
3. Still wait_for_schema_agreement() if an OperationTimeoutError occurred there was no sleep between attempts, which caused test_refresh_schema_timeout() to hang because it used FakeTime and no FakeTime ever elapsed. It is also very tight busy waiting, which is sub-optimal.

My changes are:

1. Use the Cluster's class level 'control_connection_timeout' as the default for the __init__() argument
2. In wait_for_schema_agreement() use the self._timeout (passed  from Cluster) to compute the actual timeout
3. Added poll_interval = 0.2, and sleep when an operation times out before attempting again (fixes the test and makes the busy waiting more relaxed)

Subject: [PATCH 1754/4528] Python SortedSet for platforms without blist

Fixes PYTHON-104
Fixes PYTHON-167
Addresses CASSANDRA-8030

For nested UDTs and collections, the set we return must accommodate
non-hashable objects (built-in set does not).

Subject: [PATCH 1771/4528] Trivial: fix typos; improve docstring example

It's not explicit that the alternate function accepts all the arguments
of execute_concurrent until looking at the source code. I think that
adding the concurrency=50 argument to the example in the docstring
satisfies this.

My first idea was to explicitly name the concurrency and
exit_on_first_error args, but then we'd have to maintain two functions
in the future instead of of one.

Subject: [PATCH 1783/4528] Added SSL support in GeventConnection

* Calling ssl.wrap_socket() if ssl_options are given
* Removed useless select() code in the read and write greenlets, that
  was causing weird deadlocks in SSL mode

+========================
+Third party integrations
+========================
+
+
+Celery
+------
+
+Here's how, in substance, CQLengine can be plugged to `Celery
+<http://celery.readthedocs.org/>`_:
+
+.. code-block:: python
+
+    from celery import Celery
+    from celery.signals import worker_process_init, beat_init
+    from cqlengine import connection
+    from cqlengine.connection import (
+        cluster as cql_cluster, session as cql_session)
+
+    def cassandra_init():
+        """ Initialize a clean Cassandra connection. """
+        if cql_cluster is not None:
+            cql_cluster.shutdown()
+        if cql_session is not None:
+            cql_session.shutdown()
+        connection.setup()
+
+    # Initialize worker context for both standard and periodic tasks.
+    worker_process_init.connect(cassandra_init)
+    beat_init.connect(cassandra_init)
+
+    app = Celery()
+
+For more details, see `issue #237
+<https://github.com/cqlengine/cqlengine/issues/237>`_.
+
+
+uWSGI
+-----
+
+This is the code required for proper connection handling of CQLengine for a
+`uWSGI <https://uwsgi-docs.readthedocs.org>`_-run application:
+
+.. code-block:: python
+
+    from cqlengine import connection
+    from cqlengine.connection import (
+        cluster as cql_cluster, session as cql_session)
+
+    try:
+        from uwsgidecorators import postfork
+    except ImportError:
+        # We're not in a uWSGI context, no need to hook Cassandra session
+        # initialization to the postfork event.
+        pass
+    else:
+        @postfork
+        def cassandra_init():
+            """ Initialize a new Cassandra session in the context.
+
+            Ensures that a new session is returned for every new request.
+            """
+            if cql_cluster is not None:
+                cql_cluster.shutdown()
+            if cql_session is not None:
+                cql_session.shutdown()
+            connection.setup()

+Per Query Timeouts
+===================
+
+By default all queries are executed with the timeout defined in `~cqlengine.connection.setup()`
+The examples below show how to specify a per-query timeout.
+A timeout is specified in seconds and can be an int, float or None.
+None means no timeout.

+    .. code-block:: python
+
+        class Row(Model):
+            id = columns.Integer(primary_key=True)
+            name = columns.Text()
+
+
+    Fetch all objects with a timeout of 5 seconds
+    .. code-block:: python
+
+        Row.objects().timeout(5).all()
+
+    Save a single row with a 50ms timeout
+    .. code-block:: python
+
+        Row(id=1, name='Jon').timeout(0.05).save()
+
+    Delete a single row with no timeout
+    .. code-block:: python
+
+        Row(id=1).timeout(None).delete()
+
+    Update a single row with no timeout
+    .. code-block:: python
+
+        Row(id=1).timeout(None).update(name='Blake')
+
+    Batch query timeouts
+    .. code-block:: python
+
+        with BatchQuery(timeout=10) as b:
+            Row(id=1, name='Jon').save()
+
+
+    NOTE: You cannot set both timeout and batch at the same time, batch will use the timeout defined in it's constructor.
+    Setting the timeout on the model is meaningless and will raise an AssertionError.

-Subject: don't use ez_setup
-
-Debian packages aren't supposed to download stuff while building, and
-since the version of setuptools in stable is less than the one ez_setup
-wants, and since some system python packages don't ship their .egg-info
-directories, it might try.
-
-It's ok though, we can rely on the Depends and Build-Depends for making
-sure python-setuptools and the various other deps are around at the right
-times.

Subject: [PATCH 1847/4528] Make keyspace settable on all statement types

Change Statement.keyspace to be handled more like routing_key:
- now settable on simplestatements
- now set implicitly along with routing key in batch statements

Also:
- changed BoundStatement.bind to raise if not enough parameters for routing key
- fixed minor typo in example in comments

Subject: [PATCH 1886/4528] Prevent NIE when unknown repl strategy with TA LBP

Unknown replication strategies would raise if token aware load balancing
used.
Also fixes a more general issue where TokenAware blows up with
strategies returning an empty mapping (i.e. LocalStrategy, and Unknown).

 Before testing, you'll need to set an environment variable to the version of Cassandra that's being tested.  The version cooresponds to the <Major><Minor> release, so for example if you're testing against Cassandra 2.1, you'd set the following:
 
-    .. code-block::bash
+.. code-block:: bash
 
-        export CASSANDRA_VERSION=20
+    export CASSANDRA_VERSION=20
 
 At the command line, execute:
 
-    .. code-block::bash
+.. code-block:: bash
 
-        bin/test.py
+    bin/test.py
 
 This is a wrapper for nose that also sets up the database connection.

Subject: [PATCH 1901/4528] Properly handle unhexlify argument type and return
 type in Python 3

When the schema contains user defined types, binascii.uhexlify gets called.
In Python 3 unhexlify accepts "only bytestring or bytearray objects as input"
and returns bytes too. This caused apply_parameters to crash.
Now for Python 3 there'a a wrapper than accepts str or bytes and returns str.

From 4bb8b313c0d684b286904cbe4ac962fdf73b5dd1 Mon Sep 17 00:00:00 2001
From: Jon Haddad <jon@jonhaddad.com>
Date: Wed, 14 Jan 2015 08:35:37 -0800
Subject: [PATCH 1922/4528] made create_keyspace more sane, fixed broken tests.

create_keyspace no longer has defaults for SimpleStrategy and
replication factor.  changed tests to use the default keyspace,
cqlengine_test for all tests.  Not sure why other keyspaces were being
used.

 CHANGELOG
 
+0.21.0
+
+Create keyspace no longer defaults to SimpleStrategy with 3 replicas.  It must be manually specified.
+sync_table() no longer has an option to create keyspaces automatically.
+cqlengine_test is now the default keyspace used for tests and is explicitly created
+all references hardcoded to the "test" keyspace have been removed and use the default instead
+instead of testing with bin/nose, use setup_package
+improved validation error messages to include column name
+fixed updating empty sets
+improvements to puppet download script
+per query timeouts now supported, see https://cqlengine.readthedocs.org/en/latest/topics/queryset.html?highlight=timeout#per-query-timeouts
+
 0.19.0
 
 Fixed tests with Cassandra version 1.2 and 2.1

Subject: [PATCH 1930/4528] Updates to 'date' and 'time' type handling.

datetime.date --> 'date'
datetime.time --> 'time'

datetime.time seemed to be the best native type for time, but it doesn't
have nanosecond resolution. Clients must use int types for that.

-### Contributing code to cqlengine
-
-Before submitting a pull request, please make sure that it follows these guidelines:
-
-* Limit yourself to one feature or bug fix per pull request.
-* Include unittests that thoroughly test the feature/bug fix
-* Write clear, descriptive commit messages.
-* Many granular commits are preferred over large monolithic commits
-* If you're adding or modifying features, please update the documentation
-
-If you're working on a big ticket item, please check in on [cqlengine-users](https://groups.google.com/forum/?fromgroups#!forum/cqlengine-users).
-We'd hate to have to steer you in a different direction after you've already put in a lot of hard work.

-0.15 Upgrade to use Datastax Native Driver
-
-We no longer raise cqlengine based OperationalError when connection fails.  Now using the exception thrown in the native driver.
-
-If you're calling setup() with the old thrift port in place, you will get connection errors.  Either remove it (the default native port is assumed) or change to the default native port, 9042.
-
-The cqlengine connection pool has been removed.  Connections are now managed by the native driver.  This should drastically reduce the socket overhead as the native driver can multiplex queries.
-
-If you were previously manually using "ALL", "QUORUM", etc, to specificy consistency levels, you will need to migrate to the cqlengine.ALL, QUORUM, etc instead.  If you had been using the module level constants before, nothing should need to change.
-
-No longer accepting username & password as arguments to setup.  Use the native driver's authentication instead.  See http://datastax.github.io/python-driver/api/cassandra/auth.html

-## Installation
-```
-pip install cqlengine
-```
-
-## Getting Started on your local machine
-
-```python
-#first, define a model
-import uuid
-from cqlengine import columns
-from cqlengine.models import Model
-
-class ExampleModel(Model):
-    read_repair_chance = 0.05 # optional - defaults to 0.1
-    example_id      = columns.UUID(primary_key=True, default=uuid.uuid4)
-    example_type    = columns.Integer(index=True)
-    created_at      = columns.DateTime()
-    description     = columns.Text(required=False)
-
-#next, setup the connection to your cassandra server(s) and the default keyspace...
->>> from cqlengine import connection
->>> connection.setup(['127.0.0.1'], "cqlengine")
-
-# or if you're still on cassandra 1.2
->>> connection.setup(['127.0.0.1'], "cqlengine", protocol_version=1)
-
-# create your keyspace.  This is, in general, not what you want in production
-# see https://cassandra.apache.org/doc/cql3/CQL.html#createKeyspaceStmt for options
->>> create_keyspace("cqlengine", "SimpleStrategy", 1)
-
-#...and create your CQL table
->>> from cqlengine.management import sync_table
->>> sync_table(ExampleModel)
-
-#now we can create some rows:
->>> em1 = ExampleModel.create(example_type=0, description="example1", created_at=datetime.now())
->>> em2 = ExampleModel.create(example_type=0, description="example2", created_at=datetime.now())
->>> em3 = ExampleModel.create(example_type=0, description="example3", created_at=datetime.now())
->>> em4 = ExampleModel.create(example_type=0, description="example4", created_at=datetime.now())
->>> em5 = ExampleModel.create(example_type=1, description="example5", created_at=datetime.now())
->>> em6 = ExampleModel.create(example_type=1, description="example6", created_at=datetime.now())
->>> em7 = ExampleModel.create(example_type=1, description="example7", created_at=datetime.now())
->>> em8 = ExampleModel.create(example_type=1, description="example8", created_at=datetime.now())
-
-#and now we can run some queries against our table
->>> ExampleModel.objects.count()
-8
->>> q = ExampleModel.objects(example_type=1)
->>> q.count()
-4
->>> for instance in q:
->>>     print instance.description
-example5
-example6
-example7
-example8
-
-#here we are applying additional filtering to an existing query
-#query objects are immutable, so calling filter returns a new
-#query object
->>> q2 = q.filter(example_id=em5.example_id)
-
->>> q2.count()
-1
->>> for instance in q2:
->>>     print instance.description
-example5

+
+Columns
+-------
+
+    Columns in your models map to columns in your CQL table. You define CQL columns by defining column attributes on your model classes.
+    For a model to be valid it needs at least one primary key column and one non-primary key column.
+
+    Just as in CQL, the order you define your columns in is important, and is the same order they are defined in on a model's corresponding table.
+
+    Each column on your model definitions needs to be an instance of a Column class.

+Model
+-----
+.. autoclass:: Model(\*\*kwargs)
+
+    The initializer creates an instance of the model. Pass in keyword arguments for columns you've defined on the model.
+
+    .. code-block:: python
+        class Person(Model):
+            id = columns.UUID(primary_key=True)
+            first_name  = columns.Text()

+        person.first_name  #returns 'Blake'
+        person.last_name  #returns 'Eggleston'
+
+    *Model attributes define how the model maps to tables in the database. These are class variables that should be set
+    when defining Model deriviatives.*
+
+    .. autoattribute:: __abstract__
+        :annotation:  = False
+
+    .. autoattribute:: __table_name__

+
+        See :ref:`table_polymorphism` for usage examples.
+
+    *Each table can have its own set of configuration options.
+    These can be specified on a model with the following attributes:*
+
+    See the `list of supported table properties for more information
+    <http://www.datastax.com/documentation/cql/3.1/cql/cql_reference/tabProp.html>`_.

+
+    .. attribute:: __read_repair_chance__
+
+    .. attribute:: __replicate_on_write__
+
+
+    *Model presently supports specifying compaction options via class attributes. 
+    cqlengine will only use your compaction options if you have a strategy set.
+    When a table is synced, it will be altered to match the compaction options set on your table.
+    This means that if you are changing settings manually they will be changed back on resync.*
+
+    *Do not use the compaction settings of cqlengine if you want to manage your compaction settings manually.*
+
+    *cqlengine supports all compaction options as of Cassandra 1.2.8.*
+
+    **These attibutes will likely be replaced by a single options string in a future version, and are therefore deprecated.**
+

+        :annotation: Deprecated
+
+        For example:
+
+        .. code-block:: python
+
+            class User(Model):
+                __compaction__ = cqlengine.LeveledCompactionStrategy
+                __compaction_sstable_size_in_mb__ = 64
+                __compaction_tombstone_threshold__ = .2
+
+                user_id = columns.UUID(primary_key=True)
+                name = columns.Text()
+
+        or for SizeTieredCompaction:
+
+        .. code-block:: python
+
+            class TimeData(Model):
+                __compaction__ = SizeTieredCompactionStrategy
+                __compaction_bucket_low__ = .3
+                __compaction_bucket_high__ = 2
+                __compaction_min_threshold__ = 2

+                __compaction_tombstone_compaction_interval__ = 86400
+
+        Tables may use `LeveledCompactionStrategy` or `SizeTieredCompactionStrategy`.  Both options are available in the top level cqlengine module.  To reiterate, you will need to set your `__compaction__` option explicitly in order for cqlengine to handle any of your settings.
+
+    *The base methods allow creating, storing, and querying modeled objects.*
+
+    .. automethod:: create
+
+    .. method:: if_not_exists()
+
+        Check the existence of an object before insertion. The existence of an
+        object is determined by its primary key(s). And please note using this flag
+        would incur performance cost.
+
+        if the insertion didn't applied, a LWTException exception would be raised.
+
+        .. code-block:: python
+
+            try:
+                TestIfNotExistsModel.if_not_exists().create(id=id, count=9, text='111111111111')

+                # handle failure case
+                print e.existing # existing object
+
+        This method is supported on Cassandra 2.0 or later.
+
+    .. automethod:: save
+
+    .. automethod:: update
+
+    .. method:: iff(**values)
+
+        Checks to ensure that the values specified are correct on the Cassandra cluster.
+        Simply specify the column(s) and the expected value(s).  As with if_not_exists,
+        this incurs a performance cost.
+
+        If the insertion isn't applied, a LWTException is raised
+
+        .. code-block:: python

+
+        Sets the batch object to run instance updates and inserts queries with.
+
+        See :doc:`/cqlengine/batches` for usage examples
+
+    .. automethod:: timeout

+
+        Returns the number of columns defined in the model
+
+    .. method:: m[col_name]

+=============
+Batch Queries
+=============
+
+cqlengine supports batch queries using the BatchQuery class. Batch queries can be started and stopped manually, or within a context manager. To add queries to the batch object, you just need to precede the create/save/delete call with a call to batch, and pass in the batch object.
+
+
+Batch Query General Use Pattern
+===============================
+
+    You can only create, update, and delete rows with a batch query, attempting to read rows out of the database with a batch query will fail.
+
+    .. code-block:: python
+
+        from cqlengine import BatchQuery
+
+        #using a context manager
+        with BatchQuery() as b:
+            now = datetime.now()
+            em1 = ExampleModel.batch(b).create(example_type=0, description="1", created_at=now)
+            em2 = ExampleModel.batch(b).create(example_type=0, description="2", created_at=now)
+            em3 = ExampleModel.batch(b).create(example_type=0, description="3", created_at=now)
+
+        # -- or --
+
+        #manually
+        b = BatchQuery()
+        now = datetime.now()
+        em1 = ExampleModel.batch(b).create(example_type=0, description="1", created_at=now)
+        em2 = ExampleModel.batch(b).create(example_type=0, description="2", created_at=now)
+        em3 = ExampleModel.batch(b).create(example_type=0, description="3", created_at=now)
+        b.execute()
+
+        # updating in a batch
+
+        b = BatchQuery()
+        em1.description = "new description"
+        em1.batch(b).save()
+        em2.description = "another new description"
+        em2.batch(b).save()
+        b.execute()
+
+        # deleting in a batch
+        b = BatchQuery()
+        ExampleModel.objects(id=some_id).batch(b).delete()
+        ExampleModel.objects(id=some_id2).batch(b).delete()
+        b.execute()
+
+
+    Typically you will not want the block to execute if an exception occurs inside the `with` block.  However, in the case that this is desirable, it's achievable by using the following syntax:
+
+    .. code-block:: python
+
+        with BatchQuery(execute_on_exception=True) as b:
+            LogEntry.batch(b).create(k=1, v=1)
+            mystery_function() # exception thrown in here
+            LogEntry.batch(b).create(k=1, v=2) # this code is never reached due to the exception, but anything leading up to here will execute in the batch.
+
+    If an exception is thrown somewhere in the block, any statements that have been added to the batch will still be executed.  This is useful for some logging situations.
+
+Batch Query Execution Callbacks
+===============================
+
+    In order to allow secondary tasks to be chained to the end of batch, BatchQuery instances allow callbacks to be
+    registered with the batch, to be executed immediately after the batch executes.
+
+    Multiple callbacks can be attached to same BatchQuery instance, they are executed in the same order that they
+    are added to the batch.
+
+    The callbacks attached to a given batch instance are executed only if the batch executes. If the batch is used as a
+    context manager and an exception is raised, the queued up callbacks will not be run.
+
+    .. code-block:: python
+
+        def my_callback(*args, **kwargs):
+            pass
+
+        batch = BatchQuery()
+
+        batch.add_callback(my_callback)
+        batch.add_callback(my_callback, 'positional arg', named_arg='named arg value')
+
+        # if you need reference to the batch within the callback,
+        # just trap it in the arguments to be passed to the callback:
+        batch.add_callback(my_callback, cqlengine_batch=batch)
+
+        # once the batch executes...
+        batch.execute()
+
+        # the effect of the above scheduled callbacks will be similar to
+        my_callback()
+        my_callback('positional arg', named_arg='named arg value')
+        my_callback(cqlengine_batch=batch)
+
+    Failure in any of the callbacks does not affect the batch's execution, as the callbacks are started after the execution
+    of the batch is complete.
+
+Logged vs Unlogged Batches
+---------------------------
+    By default, queries in cqlengine are LOGGED, which carries additional overhead from UNLOGGED.  To explicitly state which batch type to use, simply:
+
+
+    .. code-block:: python
+
+        from cqlengine.query import BatchType
+        with BatchQuery(batch_type=BatchType.Unlogged) as b:
+            LogEntry.batch(b).create(k=1, v=1)
+            LogEntry.batch(b).create(k=1, v=2)

-Columns
-=======
-
-    Columns in your models map to columns in your CQL table. You define CQL columns by defining column attributes on your model classes. For a model to be valid it needs at least one primary key column and one non-primary key column.
-
-    Just as in CQL, the order you define your columns in is important, and is the same order they are defined in on a model's corresponding table.
-
-Column Types
-============
-
-    Each column on your model definitions needs to an instance of a Column class. The column types that are included with cqlengine as of this writing are:
-
-    * :class:`~cqlengine.columns.Bytes`
-    * :class:`~cqlengine.columns.Ascii`
-    * :class:`~cqlengine.columns.Text`
-    * :class:`~cqlengine.columns.Integer`
-    * :class:`~cqlengine.columns.BigInt`
-    * :class:`~cqlengine.columns.DateTime`
-    * :class:`~cqlengine.columns.UUID`
-    * :class:`~cqlengine.columns.TimeUUID`
-    * :class:`~cqlengine.columns.Boolean`
-    * :class:`~cqlengine.columns.Float`
-    * :class:`~cqlengine.columns.Decimal`
-    * :class:`~cqlengine.columns.Set`
-    * :class:`~cqlengine.columns.List`
-    * :class:`~cqlengine.columns.Map`
-
-Column Options
---------------
-
-    Each column can be defined with optional arguments to modify the way they behave. While some column types may
-    define additional column options, these are the options that are available on all columns:
-
-    :attr:`~cqlengine.columns.BaseColumn.primary_key`
-        If True, this column is created as a primary key field. A model can have multiple primary keys. Defaults to False.
-
-        *In CQL, there are 2 types of primary keys: partition keys and clustering keys. As with CQL, the first
-        primary key is the partition key, and all others are clustering keys, unless partition keys are specified
-        manually using* :attr:`~cqlengine.columns.BaseColumn.partition_key`
-
-    :attr:`~cqlengine.columns.BaseColumn.partition_key`
-        If True, this column is created as partition primary key. There may be many partition keys defined,
-        forming a *composite partition key*
-
-    :attr:`~cqlengine.columns.BaseColumn.clustering_order`
-        ``ASC`` or ``DESC``, determines the clustering order of a clustering key.
-
-    :attr:`~cqlengine.columns.BaseColumn.index`
-        If True, an index will be created for this column. Defaults to False.
-
-    :attr:`~cqlengine.columns.BaseColumn.db_field`
-        Explicitly sets the name of the column in the database table. If this is left blank, the column name will be
-        the same as the name of the column attribute. Defaults to None.
-
-    :attr:`~cqlengine.columns.BaseColumn.default`
-        The default value for this column. If a model instance is saved without a value for this column having been
-        defined, the default value will be used. This can be either a value or a callable object (ie: datetime.now is a valid default argument).
-        Callable defaults will be called each time a default is assigned to a None value
-
-    :attr:`~cqlengine.columns.BaseColumn.required`
-        If True, this model cannot be saved without a value defined for this column. Defaults to False. Primary key fields always require values.
-
-    :attr:`~cqlengine.columns.BaseColumn.static`
-        Defined a column as static.  Static columns are shared by all rows in a partition.
-
-Model Methods
-=============
-    Below are the methods that can be called on model instances.
-
-.. class:: Model(\*\*values)
-
-    Creates an instance of the model. Pass in keyword arguments for columns you've defined on the model.
-
-    *Example*
-
-    .. code-block:: python
-
-        #using the person model from earlier:
-        class Person(Model):
-            id = columns.UUID(primary_key=True)
-            first_name  = columns.Text()
-            last_name = columns.Text()
-
-        person = Person(first_name='Blake', last_name='Eggleston')
-        person.first_name  #returns 'Blake'
-        person.last_name  #returns 'Eggleston'
-
-
-    .. method:: save()
-
-        Saves an object to the database
-
-        *Example*
-
-        .. code-block:: python
-
-            #create a person instance
-            person = Person(first_name='Kimberly', last_name='Eggleston')
-            #saves it to Cassandra
-            person.save()
-
-    .. method:: delete()
-
-        Deletes the object from the database.
-
-    .. method:: batch(batch_object)
-
-        Sets the batch object to run instance updates and inserts queries with.
-
-    .. method:: timestamp(timedelta_or_datetime)
-
-        Sets the timestamp for the query
-
-    .. method:: ttl(ttl_in_sec)
-
-        Sets the ttl values to run instance updates and inserts queries with.
-
-    .. method:: if_not_exists()
-
-        Check the existence of an object before insertion. The existence of an
-        object is determined by its primary key(s). And please note using this flag
-        would incur performance cost.
-
-        if the insertion didn't applied, a LWTException exception would be raised.
-
-        *Example*
-
-        .. code-block:: python
-            try:
-                TestIfNotExistsModel.if_not_exists().create(id=id, count=9, text='111111111111')
-            except LWTException as e:
-                # handle failure case
-                print e.existing # existing object
-
-        This method is supported on Cassandra 2.0 or later.
-
-    .. method:: iff(**values)
-
-        Checks to ensure that the values specified are correct on the Cassandra cluster.
-        Simply specify the column(s) and the expected value(s).  As with if_not_exists,
-        this incurs a performance cost.
-
-        If the insertion isn't applied, a LWTException is raised
-
-        .. code-block::
-            t = TestTransactionModel(text='some text', count=5)
-            try:
-                 t.iff(count=5).update('other text')
-            except LWTException as e:
-                # handle failure
-
-    .. method:: update(**values)
-
-        Performs an update on the model instance. You can pass in values to set on the model
-        for updating, or you can call without values to execute an update against any modified
-        fields. If no fields on the model have been modified since loading, no query will be
-        performed. Model validation is performed normally.
-
-        It is possible to do a blind update, that is, to update a field without having first selected the object out of the database.  See :ref:`Blind Updates <blind_updates>`
-
-    .. method:: get_changed_columns()
-
-        Returns a list of column names that have changed since the model was instantiated or saved
-
-Model Attributes
-================
-
-    .. attribute:: Model.__abstract__
-
-        *Optional.* Indicates that this model is only intended to be used as a base class for other models. You can't create tables for abstract models, but checks around schema validity are skipped during class construction.
-
-    .. attribute:: Model.__table_name__
-
-        *Optional.* Sets the name of the CQL table for this model. If left blank, the table name will be the name of the model, with it's module name as it's prefix. Manually defined table names are not inherited.
-
-    .. _keyspace-change:
-    .. attribute:: Model.__keyspace__
-
-        Sets the name of the keyspace used by this model.
-
-        **Prior to cqlengine 0.16, this setting defaulted
-        to 'cqlengine'. As of 0.16, this field needs to be set on all non-abstract models, or their base classes.**
+For examples on manipulating data and creating queries, see :doc:`queryset`
 
-    .. _ttl-change:
-    .. attribute:: Model.__default_ttl__
-
-        Sets the default ttl used by this model.  This can be overridden by using the ``ttl(ttl_in_sec)`` method.
-
-
-Table Polymorphism
-==================
-
-    As of cqlengine 0.8, it is possible to save and load different model classes using a single CQL table.
-    This is useful in situations where you have different object types that you want to store in a single cassandra row.
-
-    For instance, suppose you want a table that stores rows of pets owned by an owner:
-
-    .. code-block:: python
-
-        class Pet(Model):
-            __table_name__ = 'pet'
-            owner_id = UUID(primary_key=True)
-            pet_id = UUID(primary_key=True)
-            pet_type = Text(polymorphic_key=True)
-            name = Text()
-
-            def eat(self, food):
-                pass
-
-            def sleep(self, time):
-                pass
-
-        class Cat(Pet):
-            __polymorphic_key__ = 'cat'
-            cuteness = Float()
-
-            def tear_up_couch(self):
-                pass
-
-        class Dog(Pet):
-            __polymorphic_key__ = 'dog'
-            fierceness = Float()
-
-            def bark_all_night(self):
-                pass
-
-    After calling ``sync_table`` on each of these tables, the columns defined in each model will be added to the
-    ``pet`` table. Additionally, saving ``Cat`` and ``Dog`` models will save the meta data needed to identify each row
-    as either a cat or dog.
+Manipulating model instances as dictionaries
+============================================
 
-    To setup a polymorphic model structure, follow these steps
+Model instances can be accessed like dictionaries.
 
-    1.  Create a base model with a column set as the polymorphic_key (set ``polymorphic_key=True`` in the column definition)
-    2.  Create subclass models, and define a unique ``__polymorphic_key__`` value on each
-    3.  Run ``sync_table`` on each of the sub tables
+.. code-block:: python
 
-    **About the polymorphic key**
+    class Person(Model):
+        first_name  = columns.Text()
+        last_name = columns.Text()
 
-    The polymorphic key is what cqlengine uses under the covers to map logical cql rows to the appropriate model type. The
-    base model maintains a map of polymorphic keys to subclasses. When a polymorphic model is saved, this value is automatically
-    saved into the polymorphic key column. You can set the polymorphic key column to any column type that you like, with
-    the exception of container and counter columns, although ``Integer`` columns make the most sense. Additionally, if you
-    set ``index=True`` on your polymorphic key column, you can execute queries against polymorphic subclasses, and a
-    ``WHERE`` clause will be automatically added to your query, returning only rows of that type. Note that you must
-    define a unique ``__polymorphic_key__`` value to each subclass, and that you can only assign a single polymorphic
-    key column per model
+    kevin = Person.create(first_name="Kevin", last_name="Deldycke")
+    dict(kevin)  # returns {'first_name': 'Kevin', 'last_name': 'Deldycke'}
+    kevin['first_name']  # returns 'Kevin'
+    kevin.keys()  # returns ['first_name', 'last_name']
+    kevin.values()  # returns ['Kevin', 'Deldycke']
+    kevin.items()  # returns [('first_name', 'Kevin'), ('last_name', 'Deldycke')]
 
+    kevin['first_name'] = 'KEVIN5000'  # changes the models first name
 
 Extending Model Validation
 ==========================
 
-    Each time you save a model instance in cqlengine, the data in the model is validated against the schema you've defined
-    for your model. Most of the validation is fairly straightforward, it basically checks that you're not trying to do
-    something like save text into an integer column, and it enforces the ``required`` flag set on column definitions.
-    It also performs any transformations needed to save the data properly.
-
-    However, there are often additional constraints or transformations you want to impose on your data, beyond simply
-    making sure that Cassandra won't complain when you try to insert it. To define additional validation on a model,
-    extend the model's validation method:
-
-    .. code-block:: python
-
-        class Member(Model):
-            person_id = UUID(primary_key=True)
-            name = Text(required=True)
-
-            def validate(self):
-                super(Member, self).validate()
-                if self.name == 'jon':
-                    raise ValidationError('no jon\'s allowed')
-
-    *Note*: while not required, the convention is to raise a ``ValidationError`` (``from cqlengine import ValidationError``)
-    if validation fails
-
-
-Table Properties
-================
-
-    Each table can have its own set of configuration options.
-    These can be specified on a model with the following attributes:
-
-    .. attribute:: Model.__bloom_filter_fp_chance
-
-    .. attribute:: Model.__caching__
+Each time you save a model instance in cqlengine, the data in the model is validated against the schema you've defined
+for your model. Most of the validation is fairly straightforward, it basically checks that you're not trying to do
+something like save text into an integer column, and it enforces the ``required`` flag set on column definitions.
+It also performs any transformations needed to save the data properly.
 
-    .. attribute:: Model.__comment__
+However, there are often additional constraints or transformations you want to impose on your data, beyond simply
+making sure that Cassandra won't complain when you try to insert it. To define additional validation on a model,
+extend the model's validation method:
 
-    .. attribute:: Model.__dclocal_read_repair_chance__
-
-    .. attribute:: Model.__default_time_to_live__
-
-    .. attribute:: Model.__gc_grace_seconds__
-
-    .. attribute:: Model.__index_interval__
-
-    .. attribute:: Model.__memtable_flush_period_in_ms__
-
-    .. attribute:: Model.__populate_io_cache_on_flush__
-
-    .. attribute:: Model.__read_repair_chance__
-
-    .. attribute:: Model.__replicate_on_write__
-
-    Example:
-
-    .. code-block:: python
-
-        from cqlengine import CACHING_ROWS_ONLY, columns
-        from cqlengine.models import Model
-
-        class User(Model):
-            __caching__ = CACHING_ROWS_ONLY  # cache only rows instead of keys only by default
-            __gc_grace_seconds__ = 86400  # 1 day instead of the default 10 days
-
-            user_id = columns.UUID(primary_key=True)
-            name = columns.Text()
-
-    Will produce the following CQL statement:
+.. code-block:: python
 
-    .. code-block:: sql
+    class Member(Model):
+        person_id = UUID(primary_key=True)
+        name = Text(required=True)
 
-        CREATE TABLE cqlengine.user (
-            user_id uuid,
-            name text,
-            PRIMARY KEY (user_id)
-        ) WITH caching = 'rows_only'
-           AND gc_grace_seconds = 86400;
+        def validate(self):
+            super(Member, self).validate()
+            if self.name == 'jon':
+                raise ValidationError('no jon\'s allowed')
 
-    See the `list of supported table properties for more information
-    <http://www.datastax.com/documentation/cql/3.1/cql/cql_reference/tabProp.html>`_.

-Compaction Options
+Table Polymorphism
 ==================
+It is possible to save and load different model classes using a single CQL table.
+This is useful in situations where you have different object types that you want to store in a single cassandra row.
 
-    As of cqlengine 0.7 we've added support for specifying compaction options.  cqlengine will only use your compaction options if you have a strategy set.  When a table is synced, it will be altered to match the compaction options set on your table.  This means that if you are changing settings manually they will be changed back on resync.  Do not use the compaction settings of cqlengine if you want to manage your compaction settings manually.
-
-    cqlengine supports all compaction options as of Cassandra 1.2.8.
+For instance, suppose you want a table that stores rows of pets owned by an owner:
 
-    Available Options:
-
-    .. attribute:: Model.__compaction_bucket_high__
-
-    .. attribute:: Model.__compaction_bucket_low__
-
-    .. attribute:: Model.__compaction_max_compaction_threshold__
-
-    .. attribute:: Model.__compaction_min_compaction_threshold__
-
-    .. attribute:: Model.__compaction_min_sstable_size__
-
-    .. attribute:: Model.__compaction_sstable_size_in_mb__
-
-    .. attribute:: Model.__compaction_tombstone_compaction_interval__
-
-    .. attribute:: Model.__compaction_tombstone_threshold__
-
-    For example:
-
-    .. code-block:: python
-
-        class User(Model):
-            __compaction__ = cqlengine.LeveledCompactionStrategy
-            __compaction_sstable_size_in_mb__ = 64
-            __compaction_tombstone_threshold__ = .2
-
-            user_id = columns.UUID(primary_key=True)
-            name = columns.Text()
+.. code-block:: python
 
-    or for SizeTieredCompaction:
+    class Pet(Model):
+        __table_name__ = 'pet'
+        owner_id = UUID(primary_key=True)
+        pet_id = UUID(primary_key=True)
+        pet_type = Text(polymorphic_key=True)
+        name = Text()
 
-    .. code-block:: python
+        def eat(self, food):
+            pass
 
-        class TimeData(Model):
-            __compaction__ = SizeTieredCompactionStrategy
-            __compaction_bucket_low__ = .3
-            __compaction_bucket_high__ = 2
-            __compaction_min_threshold__ = 2
-            __compaction_max_threshold__ = 64
-            __compaction_tombstone_compaction_interval__ = 86400
+        def sleep(self, time):
+            pass
 
-    Tables may use `LeveledCompactionStrategy` or `SizeTieredCompactionStrategy`.  Both options are available in the top level cqlengine module.  To reiterate, you will need to set your `__compaction__` option explicitly in order for cqlengine to handle any of your settings.
+    class Cat(Pet):
+        __polymorphic_key__ = 'cat'
+        cuteness = Float()
 
+        def tear_up_couch(self):
+            pass
 
-Manipulating model instances as dictionaries
-============================================
+    class Dog(Pet):
+        __polymorphic_key__ = 'dog'
+        fierceness = Float()
 
-    As of cqlengine 0.12, we've added support for treating model instances like dictionaries. See below for examples.
+        def bark_all_night(self):
+            pass
 
-    .. code-block:: python
+After calling ``sync_table`` on each of these tables, the columns defined in each model will be added to the
+``pet`` table. Additionally, saving ``Cat`` and ``Dog`` models will save the meta data needed to identify each row
+as either a cat or dog.
 
-        class Person(Model):
-            first_name  = columns.Text()
-            last_name = columns.Text()
+To setup a polymorphic model structure, follow these steps
 
-        kevin = Person.create(first_name="Kevin", last_name="Deldycke")
-        dict(kevin)  # returns {'first_name': 'Kevin', 'last_name': 'Deldycke'}
-        kevin['first_name']  # returns 'Kevin'
-        kevin.keys()  # returns ['first_name', 'last_name']
-        kevin.values()  # returns ['Kevin', 'Deldycke']
-        kevin.items()  # returns [('first_name', 'Kevin'), ('last_name', 'Deldycke')]
+1.  Create a base model with a column set as the polymorphic_key (set ``polymorphic_key=True`` in the column definition)
+2.  Create subclass models, and define a unique ``__polymorphic_key__`` value on each
+3.  Run ``sync_table`` on each of the sub tables
 
-        kevin['first_name'] = 'KEVIN5000'  # changes the models first name

-Batch Queries
-=============
-
-    cqlengine now supports batch queries using the BatchQuery class. Batch queries can be started and stopped manually, or within a context manager. To add queries to the batch object, you just need to precede the create/save/delete call with a call to batch, and pass in the batch object.
-
-
-
-Batch Query General Use Pattern
--------------------------------
-
-    You can only create, update, and delete rows with a batch query, attempting to read rows out of the database with a batch query will fail.
-
-    .. code-block:: python
-
-        from cqlengine import BatchQuery
-
-        #using a context manager
-        with BatchQuery() as b:
-            now = datetime.now()
-            em1 = ExampleModel.batch(b).create(example_type=0, description="1", created_at=now)
-            em2 = ExampleModel.batch(b).create(example_type=0, description="2", created_at=now)
-            em3 = ExampleModel.batch(b).create(example_type=0, description="3", created_at=now)
-
-        # -- or --
-
-        #manually
-        b = BatchQuery()
-        now = datetime.now()
-        em1 = ExampleModel.batch(b).create(example_type=0, description="1", created_at=now)
-        em2 = ExampleModel.batch(b).create(example_type=0, description="2", created_at=now)
-        em3 = ExampleModel.batch(b).create(example_type=0, description="3", created_at=now)
-        b.execute()
-
-        # updating in a batch
-
-        b = BatchQuery()
-        em1.description = "new description"
-        em1.batch(b).save()
-        em2.description = "another new description"
-        em2.batch(b).save()
-        b.execute()
-
-        # deleting in a batch
-        b = BatchQuery()
-        ExampleModel.objects(id=some_id).batch(b).delete()
-        ExampleModel.objects(id=some_id2).batch(b).delete()
-        b.execute()
-
-
-    Typically you will not want the block to execute if an exception occurs inside the `with` block.  However, in the case that this is desirable, it's achievable by using the following syntax:
-
-    .. code-block:: python
-
-        with BatchQuery(execute_on_exception=True) as b:
-            LogEntry.batch(b).create(k=1, v=1)
-            mystery_function() # exception thrown in here
-            LogEntry.batch(b).create(k=1, v=2) # this code is never reached due to the exception, but anything leading up to here will execute in the batch.
-
-    If an exception is thrown somewhere in the block, any statements that have been added to the batch will still be executed.  This is useful for some logging situations.
-
-Batch Query Execution Callbacks
--------------------------------
-
-    In order to allow secondary tasks to be chained to the end of batch, BatchQuery instances allow callbacks to be
-    registered with the batch, to be executed immediately after the batch executes.
-
-    Multiple callbacks can be attached to same BatchQuery instance, they are executed in the same order that they
-    are added to the batch.
-
-    The callbacks attached to a given batch instance are executed only if the batch executes. If the batch is used as a
-    context manager and an exception is raised, the queued up callbacks will not be run.
-
-    .. code-block:: python
-
-        def my_callback(*args, **kwargs):
-            pass
-
-        batch = BatchQuery()
-
-        batch.add_callback(my_callback)
-        batch.add_callback(my_callback, 'positional arg', named_arg='named arg value')
-
-        # if you need reference to the batch within the callback,
-        # just trap it in the arguments to be passed to the callback:
-        batch.add_callback(my_callback, cqlengine_batch=batch)
-
-        # once the batch executes...
-        batch.execute()
-

-        my_callback()
-        my_callback('positional arg', named_arg='named arg value')
-        my_callback(cqlengine_batch=batch)
-
-    Failure in any of the callbacks does not affect the batch's execution, as the callbacks are started after the execution
-    of the batch is complete.
-
-Logged vs Unlogged Batches
----------------------------
-    By default, queries in cqlengine are LOGGED, which carries additional overhead from UNLOGGED.  To explicitly state which batch type to use, simply:
-
-
-    .. code-block:: python
-
-        from cqlengine.query import BatchType
-        with BatchQuery(batch_type=BatchType.Unlogged) as b:
-            LogEntry.batch(b).create(k=1, v=1)
-            LogEntry.batch(b).create(k=1, v=2)
-
-
-
-QuerySet method reference
-=========================
-
-.. class:: QuerySet
-
-    .. method:: all()
-
-        Returns a queryset matching all rows
-
-        .. code-block:: python
-
-            for user in User.objects().all():
-                print(user)
-
-
-    .. method:: batch(batch_object)
-
-        Sets the batch object to run the query on. Note that running a select query with a batch object will raise an exception
-
-    .. method:: consistency(consistency_setting)
-
-        Sets the consistency level for the operation.  Options may be imported from the top level :attr:`cqlengine` package.
-
-        .. code-block:: python
-
-            for user in User.objects(id=3).consistency(ONE):
-                print(user)
-
-
-    .. method:: count()
-
-        Returns the number of matching rows in your QuerySet
-
-        .. code-block:: python
-
-            print(User.objects().count())
-
-    .. method:: filter(\*\*values)
-
-        :param values: See :ref:`retrieving-objects-with-filters`
-
-        Returns a QuerySet filtered on the keyword arguments
-
-    .. method:: get(\*\*values)
-
-        :param values: See :ref:`retrieving-objects-with-filters`
-
-        Returns a single object matching the QuerySet. If no objects are matched, a :attr:`~models.Model.DoesNotExist` exception is raised. If more than one object is found, a :attr:`~models.Model.MultipleObjectsReturned` exception is raised.
-
-        .. code-block:: python
-
-            user = User.get(id=1)
-
-
-    .. method:: limit(num)
-
-        Limits the number of results returned by Cassandra.
-
-        *Note that CQL's default limit is 10,000, so all queries without a limit set explicitly will have an implicit limit of 10,000*
-
-        .. code-block:: python
-
-            for user in User.objects().limit(100):
-                print(user)
-
-    .. method:: order_by(field_name)
-
-        :param field_name: the name of the field to order on. *Note: the field_name must be a clustering key*
-        :type field_name: string
-
-        Sets the field to order on.
-
-        .. code-block:: python
-
-            from uuid import uuid1,uuid4
-
-            class Comment(Model):
-                photo_id = UUID(primary_key=True)
-                comment_id = TimeUUID(primary_key=True, default=uuid1) # auto becomes clustering key
-                comment = Text()
-
-            sync_table(Comment)
-
-            u = uuid4()
-            for x in range(5):
-                Comment.create(photo_id=u, comment="test %d" % x)
-
-            print("Normal")
-            for comment in Comment.objects(photo_id=u):
-                print comment.comment_id
-
-            print("Reversed")
-            for comment in Comment.objects(photo_id=u).order_by("-comment_id"):
-                print comment.comment_id
-
-
-    .. method:: allow_filtering()
-
-        Enables the (usually) unwise practive of querying on a clustering key without also defining a partition key
-
-    .. method:: timestamp(timestamp_or_long_or_datetime)
-
-        Allows for custom timestamps to be saved with the record.
-
-    .. method:: ttl(ttl_in_seconds)
-
-        :param ttl_in_seconds: time in seconds in which the saved values should expire
-        :type ttl_in_seconds: int
-
-        Sets the ttl to run the query query with. Note that running a select query with a ttl value will raise an exception
-
-    .. _blind_updates:
-
-    .. method:: update(**values)
-
-        Performs an update on the row selected by the queryset. Include values to update in the
-        update like so:
-
-        .. code-block:: python
-
-            Model.objects(key=n).update(value='x')
-
-        Passing in updates for columns which are not part of the model will raise a ValidationError.
-        Per column validation will be performed, but instance level validation will not
-        (`Model.validate` is not called).  This is sometimes referred to as a blind update.
-
-        For example:
-
-        .. code-block:: python
-
-            class User(Model):
-                id = Integer(primary_key=True)
-                name = Text()
-
-            setup(["localhost"], "test")
-            sync_table(User)
-
-            u = User.create(id=1, name="jon")
-
-            User.objects(id=1).update(name="Steve")
-
-            # sets name to null
-            User.objects(id=1).update(name=None)
-
-
-        The queryset update method also supports blindly adding and removing elements from container columns, without
-        loading a model instance from Cassandra.
-
-        Using the syntax `.update(column_name={x, y, z})` will overwrite the contents of the container, like updating a
-        non container column. However, adding `__<operation>` to the end of the keyword arg, makes the update call add
-        or remove items from the collection, without overwriting then entire column.
-
-
-        Given the model below, here are the operations that can be performed on the different container columns:
-
-        .. code-block:: python
-
-            class Row(Model):
-                row_id      = columns.Integer(primary_key=True)
-                set_column  = columns.Set(Integer)
-                list_column = columns.Set(Integer)
-                map_column  = columns.Set(Integer, Integer)
-
-        :class:`~cqlengine.columns.Set`
-
-        - `add`: adds the elements of the given set to the column
-        - `remove`: removes the elements of the given set to the column
-
-
-        .. code-block:: python
-
-            # add elements to a set
-            Row.objects(row_id=5).update(set_column__add={6})
-
-            # remove elements to a set
-            Row.objects(row_id=5).update(set_column__remove={4})
-
-        :class:`~cqlengine.columns.List`
-
-        - `append`: appends the elements of the given list to the end of the column
-        - `prepend`: prepends the elements of the given list to the beginning of the column
-
-        .. code-block:: python
-
-            # append items to a list
-            Row.objects(row_id=5).update(list_column__append=[6, 7])
-
-            # prepend items to a list
-            Row.objects(row_id=5).update(list_column__prepend=[1, 2])
-
-
-        :class:`~cqlengine.columns.Map`
-
-        - `update`: adds the given keys/values to the columns, creating new entries if they didn't exist, and overwriting old ones if they did
-
-        .. code-block:: python
-
-            # add items to a map
-            Row.objects(row_id=5).update(map_column__update={1: 2, 3: 4})

-Collection Type Columns
-----------------------------
-
-    CQLEngine also supports container column types. Each container column requires a column class argument to specify what type of objects it will hold. The Map column requires 2, one for the key, and the other for the value
-
-    *Example*
-
-    .. code-block:: python
-
-        class Person(Model):
-            id          = columns.UUID(primary_key=True, default=uuid.uuid4)
-            first_name  = columns.Text()
-            last_name   = columns.Text()
-
-            friends     = columns.Set(columns.Text)
-            enemies     = columns.Set(columns.Text)
-            todo_list   = columns.List(columns.Text)
-            birthdays   = columns.Map(columns.Text, columns.DateTime)
-
-
-
-.. class:: Set()
-
-    Stores a set of unordered, unique values. Available only with Cassandra 1.2 and above ::
-
-        columns.Set(value_type)
-
-    **options**
-
-        :attr:`~columns.Set.value_type`
-            The type of objects the set will contain
-
-        :attr:`~columns.Set.strict`
-            If True, adding this column will raise an exception during save if the value is not a python `set` instance. If False, it will attempt to coerce the value to a set. Defaults to True.
-
-.. class:: List()
-
-    Stores a list of ordered values. Available only with Cassandra 1.2 and above ::
-
-        columns.List(value_type)
-
-    **options**
-
-        :attr:`~columns.List.value_type`
-            The type of objects the set will contain
-
-.. class:: Map()
-
-    Stores a map (dictionary) collection, available only with Cassandra 1.2 and above ::
-
-        columns.Map(key_type, value_type)
-
-    **options**
-
-        :attr:`~columns.Map.key_type`
-            The type of the map keys
-
-        :attr:`~columns.Map.value_type`
-            The type of the map values
-
-Column Options
-==============
-
-    Each column can be defined with optional arguments to modify the way they behave. While some column types may define additional column options, these are the options that are available on all columns:
-
-    .. attribute:: BaseColumn.primary_key
-
-        If True, this column is created as a primary key field. A model can have multiple primary keys. Defaults to False.
-
-        *In CQL, there are 2 types of primary keys: partition keys and clustering keys. As with CQL, the first primary key is the partition key, and all others are clustering keys, unless partition keys are specified manually using* :attr:`BaseColumn.partition_key`
-
-    .. attribute:: BaseColumn.partition_key
-
-        If True, this column is created as partition primary key. There may be many partition keys defined, forming a *composite partition key*
-
-    .. attribute:: BaseColumn.index
-
-        If True, an index will be created for this column. Defaults to False.
-
-        *Note: Indexes can only be created on models with one primary key*
-
-    .. attribute:: BaseColumn.db_field
-
-        Explicitly sets the name of the column in the database table. If this is left blank, the column name will be the same as the name of the column attribute. Defaults to None.
-
-    .. attribute:: BaseColumn.default
-
-        The default value for this column. If a model instance is saved without a value for this column having been defined, the default value will be used. This can be either a value or a callable object (ie: datetime.now is a valid default argument).
-
-    .. attribute:: BaseColumn.required
-
-        If True, this model cannot be saved without a value defined for this column. Defaults to False. Primary key fields cannot have their required fields set to False.
-
-    .. attribute:: BaseColumn.clustering_order
-
-        Defines CLUSTERING ORDER for this column (valid choices are "asc" (default) or "desc"). It may be specified only for clustering primary keys - more: http://www.datastax.com/docs/1.2/cql_cli/cql/CREATE_TABLE#using-clustering-order

-Development
-==================
-
-Travis CI
-================
-
-Tests are run using Travis CI using a Matrix to test different Cassandra and Python versions.  It is located here: https://travis-ci.org/cqlengine/cqlengine
-
-Python versions:
-
-- 2.7
-- 3.4
-
-Cassandra vesions:
-
-- 1.2 (protocol_version 1)
-- 2.0 (protocol_version 2)
-- 2.1 (upcoming, protocol_version 3)
-
-Pull Requests
-===============
-Only Pull Requests that have passed the entire matrix will be considered for merge into the main codebase.
-
-Please see the contributing guidelines: https://github.com/cqlengine/cqlengine/blob/master/CONTRIBUTING.md
-
-
-Testing Locally
-=================
-
-Before testing, you'll need to set an environment variable to the version of Cassandra that's being tested.  The version cooresponds to the <Major><Minor> release, so for example if you're testing against Cassandra 2.1, you'd set the following:
-
-.. code-block:: bash
-
-    export CASSANDRA_VERSION=20
-
-At the command line, execute:
-
-.. code-block:: bash
-
-    bin/test.py
-
-This is a wrapper for nose that also sets up the database connection.

 Q: Why don't updates work correctly on models instantiated as Model(field=blah, field2=blah2)?
--------------------------------------------------------------------
+----------------------------------------------------------------------------------------------
 
 A: The recommended way to create new rows is with the models .create method. The values passed into a model's init method are interpreted by the model as the values as they were read from a row. This allows the model to "know" which rows have changed since the row was read out of cassandra, and create suitable update statements.

 Frequently Asked Questions
 ==========================
 
-Q: Why don't updates work correctly on models instantiated as Model(field=blah, field2=blah2)?
+Q: Why don't updates work correctly on models instantiated as Model(field=value, field2=value2)?
 ----------------------------------------------------------------------------------------------
 
 A: The recommended way to create new rows is with the models .create method. The values passed into a model's init method are interpreted by the model as the values as they were read from a row. This allows the model to "know" which rows have changed since the row was read out of cassandra, and create suitable update statements.

 Q: Why don't updates work correctly on models instantiated as Model(field=value, field2=value2)?
-----------------------------------------------------------------------------------------------
+------------------------------------------------------------------------------------------------
 
 A: The recommended way to create new rows is with the models .create method. The values passed into a model's init method are interpreted by the model as the values as they were read from a row. This allows the model to "know" which rows have changed since the row was read out of cassandra, and create suitable update statements.

Subject: [PATCH 2031/4528] Don't reverse lists in prepend context.

This rolls out workaround for a previous bug in Cassandra.
https://issues.apache.org/jira/browse/CASSANDRA-8733
If you rely on list prepend and are using this version of
the mapper with C* < [2.0.13|2.1.3], the prepended list will need to be
reversed in the application context.

Subject: [PATCH 2032/4528] Make integration tests cleanup cluster/sessions

Fixes an issue where integration suites were timing out in later tests,
due to eariler tests leaking resources.

Root cause is PYTHON-135, which points out that cluster and session
objects do not clean up properly when passing from scope. Until that is
fixed, proper cleanup will avoid these leaks.

+========================
+Upgrade Guide
+========================
+
+This is an overview of things that changed as the cqlengine project was merged into
+cassandra-driver. While efforts were taken to preserve the API and most functionality exactly,
+conversion to this package will still require certain minimal updates (namely, imports).
+
+**THERE IS ONE FUNCTIONAL CHANGE**, described in the first section below.
+
+Functional Change
+=================
+Legacy cqlengine included a workaround for a Cassandra bug in which prepended list segments were
+reversed (`CASSANDRA-8733 <https://issues.apache.org/jira/browse/CASSANDRA-8733>`_). As of
+this integration, this workaround is removed. The first released integrated version emits
+a warning when prepend is used. Subsequent versions will have this warning removed.
+
+Remove cqlengine
+================
+To avoid confusion or mistakes using the legacy package in your application, it
+is prudent to remove the cqlengine package when upgrading to the integrated version.
+
+The driver setup script will warn if the legacy package is detected during install,
+but it will not prevent side-by-side installation.
+
+Organization
+============
+Imports
+-------
+cqlengine is now integrated as a sub-package of the driver base package 'cassandra'.
+Upgrading will require adjusting imports to cqlengine. For example::
+
+    from cqlengine import columns
+
+is now::
+
+    from cassandra.cqlengine import columns
+
+Package-Level Aliases
+---------------------
+Legacy cqlengine defined a number of aliases at the package level, which became redundant
+when the package was integrated for a driver. These have been removed in favor of absolute
+imports, and referring to cannonical definitions. For example, ``cqlengine.ONE`` was an alias
+of ``cassandra.ConsistencyLevel.ONE``. In the integrated package, only the 
+:class:`cassandra.ConsistencyLevel` remains.
+
+Additionally, submodule aliases are removed from cqlengine in favor of absolute imports.
+
+These aliases are removed, and not deprecated because they should be straightforward to iron out
+at module load time.
+
+Exceptions
+----------
+The legacy cqlengine.exceptions module had a number of Exception classes that were variously
+common to the package, or only used in specific modules. Common exceptions were relocated to
+cqlengine, and specialized exceptions were placed in the module that raises them. Below is a
+listing of updated locations:
+
+============================  ==========
+Exception class               New module
+============================  ==========
+CQLEngineException            cassandra.cqlengine
+ModelException                cassandra.cqlengine.models
+ValidationError               cassandra.cqlengine
+UndefinedKeyspaceException    cassandra.cqlengine.connection
+LWTException                  cassandra.cqlengine.query
+IfNotExistsWithCounterColumn  cassandra.cqlengine.query
+============================  ==========
+
+UnicodeMixin Consolidation
+--------------------------
+``class UnicodeMixin`` was defined in several cqlengine modules. This has been consolidated
+to a single definition in the cqlengine package init file. This is not technically part of 
+the API, but noted here for completeness.
+
+API Deprecations
+================
+This upgrade served as a good juncture to deprecate certain API features and invite users to upgrade
+to new ones. The first released version does not change functionality -- only introduces deprecation
+warnings. Future releases will remove these features in favor of the alternatives.
+
+Schema Management
+-----------------
+``cassandra.cqlengine.management.create_keyspace`` is deprecated. Instead, use the new replication-strategy-specific
+functions that accept explicit options for known strategies:
+
+- :func:`~.create_keyspace_simple`
+- :func:`~.create_keyspace_network_topology`
+
+``cassandra.cqlengine.management.delete_keyspace`` is deprecated in favor of a new function, :func:`~.drop_keyspace`. The
+intent is simply to make the function match the CQL verb it invokes.
+
+Model Inheritance
+-----------------
+The names for class attributes controlling model inheritance are changing. Changes are as follows:
+
+- Replace 'polymorphic_key' in the base class Column definition with :attr:`~.discriminator_column`
+- Replace the '__polymporphic_key__' class attribute the derived classes with :attr:`~.__discriminator_value__`
+
+The functionality is unchanged -- the intent here is to make the names and language around these attributes more precise. 
+For now, the old names are just deprecated, and the mapper will emit warnings if they are used. The old names
+will be removed in a future version.
+
+The example below shows a simple translation:
+
+Before::
+
+    class Pet(Model):
+        __table_name__ = 'pet'
+        owner_id = UUID(primary_key=True)
+        pet_id = UUID(primary_key=True)
+        pet_type = Text(polymorphic_key=True)
+        name = Text()
+
+    class Cat(Pet):
+        __polymorphic_key__ = 'cat'
+
+    class Dog(Pet):
+        __polymorphic_key__ = 'dog'
+        
+After::
+
+    class Pet(models.Model):
+        __table_name__ = 'pet'
+        owner_id = UUID(primary_key=True)
+        pet_id = UUID(primary_key=True)
+        pet_type = Text(discriminator_column=True)
+        name = Text()
+
+    class Cat(Pet):
+        __discriminator_value__ = 'cat'
+
+    class Dog(Pet):
+        __discriminator_value__ = 'dog'

 Additionally, if you set ``index=True`` on your discriminator column, you can execute queries against specialized subclasses, and a

+
+User Defined Types
+==================
+cqlengine models User Defined Types (UDTs) much like tables, with fields defined by column type attributes. However, UDT instances
+are only created, presisted, and queried via table Models. A short example to introduce the pattern::
+
+    from cassandra.cqlengine.columns import *
+    from cassandra.cqlengine.models import Model
+    from cassandra.cqlengine.usertype import UserType
+
+    class address(UserType):
+        street = Text()
+        zipcode = Integer()
+
+    class users(Model):
+        __keyspace__ = 'account'
+        name = Text(primary_key=True)
+        addr = UserDefinedType(address)
+
+    sync_table(users)
+
+    users.create(name="Joe", addr=address(street="Easy St.", zip=99999))
+    user = users.objects(name="Joe")[0]
+    print user.name, user.addr
+    # Joe {'street': Easy St., 'zipcode': None}
+
+UDTs are modeled by inheriting :class:`~.usertype.UserType`, and setting column type attributes. Types are then used in defining
+models by declaring a column of type :class:`~.columns.UserDefinedType`, with the ``UserType`` class as a parameter.
+
+``sync_table`` will implicitly
+synchronize any types contained in the table. Alternatively :func:`~.management.sync_type` can be used to create/alter types
+explicitly.
+
+Upon declaration, types are automatically registered with the driver, so query results return instances of your ``UserType``
+class*.
+
+***Note**: UDTs were not added to the native protocol until v3. When setting up the cqlengine connection, be sure to specify
+``protocol_version=3``. If using an earlier version, UDT queries will still work, but the returned type will be a namedtuple.

+and custom query handlers. The payload is specified as a string:binary_type dict
+holding custom key/value pairs.
+
+By default these are ignored by the server. They can be useful for servers implementing

Subject: [PATCH 2149/4528] Remove race when adding new host during node/token
 rebuild

Fixes an issue where a race could cause None return from
Cluster.add_host during node/token list rebuild.

This would cause None to be inserted into the Token map,
and subsequently blow up TokenAware LBP creating a query plan.

Subject: [PATCH 2168/4528] Eventlet timer using eventlet.event.NOT_USED.

This works with the current implementation, but there is no guarantee
about the stability of this mechanism in eventlet events. Probably need
to synchronize Event management.

Subject: [PATCH 2209/4528] For DefaultConnection, default to gevent only if
 actually patched.

PYTHON-244
Fixes an issue where gevent is chosen based on module loaded, not monkey
patching.
In some debuggers, (PyCharm, for example), this would cause connecting
to timeout because gevent reactor is used without monkey patching.

+Frequently Asked Questions
+==========================
+
+See also :doc:`cqlengine FAQ <cqlengine/faq>`
+
+Why do connections or IO operations timeout in my WSGI application?
+-------------------------------------------------------------------
+Depending on your application process model, it may be forking after driver Session is created. Most IO reactors do not handle this, and problems will manifest as timeouts.
+
+To avoid this, make sure to create sessions per process, after the fork. Using uWSGI and Flask for example:
+
+.. code-block:: python
+
+    from flask import Flask
+    from uwsgidecorators import postfork
+    from cassandra.cluster import Cluster
+
+    session = None
+    prepared = None
+
+    @postfork
+    def connect():
+        global session, prepared
+        session = Cluster().connect()
+        prepared = session.prepare("SELECT release_version FROM system.local WHERE key=?")
+
+    app = Flask(__name__)
+
+    @app.route('/')
+    def server_version():
+        row = session.execute(prepared, ('local',))[0]
+        return row.release_version
+
+uWSGI provides a ``postfork`` hook you can use to create sessions and prepared statements after the child process forks.
+
+How do I trace a request?
+-------------------------
+Request tracing can be turned on for any request by setting ``trace=True`` in :meth:`.Session.execute_async`. View the results by waiting on the future, then :meth:`.ResponseFuture.get_query_trace`.
+Since tracing is done asynchronously to the request, this method polls until the trace is complete before querying data.
+
+.. code-block:: python
+
+    >>> future = session.execute_async("SELECT * FROM system.local", trace=True)
+    >>> result = future.result()
+    >>> trace = future.get_query_trace()
+    >>> for e in trace.events:
+    >>>     print e.source_elapsed, e.description
+
+    0:00:00.000077 Parsing select * from system.local
+    0:00:00.000153 Preparing statement
+    0:00:00.000309 Computing ranges to query
+    0:00:00.000368 Submitting range requests on 1 ranges with a concurrency of 1 (279.77142 rows per range expected)
+    0:00:00.000422 Submitted 1 concurrent range requests covering 1 ranges
+    0:00:00.000480 Executing seq scan across 1 sstables for (min(-9223372036854775808), min(-9223372036854775808))
+    0:00:00.000669 Read 1 live and 0 tombstone cells
+    0:00:00.000755 Scanned 1 rows and matched 1
+
+``trace`` is a :class:`QueryTrace` object.
+
+How do I determine the replicas for a query?
+----------------------------------------------
+With prepared statements, the replicas are obtained by ``routing_key``, based on current cluster token metadata:
+
+.. code-block:: python
+
+    >>> prepared = session.prepare("SELECT * FROM example.t WHERE key=?")
+    >>> bound = prepared.bind((1,))
+    >>> replicas = cluster.metadata.get_replicas(bound.keyspace, bound.routing_key)
+    >>> for h in replicas:
+    >>>   print h.address
+    127.0.0.1
+    127.0.0.2
+
+``replicas`` is a list of :class:`Host` objects.
+
+How does the driver manage request retries?
+-------------------------------------------
+By default, retries are managed by the :attr:`.Cluster.default_retry_policy` set on the session Cluster. It can also
+be specialized per statement by setting :attr:`.Statement.retry_policy`.
+
+Retries are presently attempted on the same coordinator, but this may change in the future.
+
+Please see :class:`.policies.RetryPolicy` for further details.

Subject: [PATCH 2264/4528] ValidationError for invalid UUID types

Follow-on to #335. Fixes issue where non-string or UUID types would
return None from UUID.validate.
Also removed test that did not do what it purported (previously
inserting None for key instead of value, and failing for Validation of
UUID and not key).

-Functional Change
-=================
+Functional Changes
+==================
+List Prepend Reversing
+----------------------
 Legacy cqlengine included a workaround for a Cassandra bug in which prepended list segments were
 reversed (`CASSANDRA-8733 <https://issues.apache.org/jira/browse/CASSANDRA-8733>`_). As of
 this integration, this workaround is removed. The first released integrated version emits
 a warning when prepend is used. Subsequent versions will have this warning removed.
 
+Date Column Type
+----------------
+The Date column type in legacy cqlengine used a ``timestamp`` CQL type and truncated the time.
+Going forward, the :class:`~.columns.Date` type represents a ``date`` for Cassandra 2.2+
+(`PYTHON-245 <https://datastax-oss.atlassian.net/browse/PYTHON-245>`_).
+Users of the legacy functionality should convert models to use :class:`~.columns.DateTime` (which
+uses ``timestamp`` internally), and use the build-in ``datetime.date`` for input values.
+
 Remove cqlengine

Subject: [PATCH 2277/4528] cqle: backport cqlengine to support Python 2.6

https://datastax-oss.atlassian.net/browse/PYTHON-288

Add Python 2.6 compliancy:
- Remove dict/set comprehensions.
- Use cassandra's OrderedDict.
- Replace str.format() implicit placeholders ('{}') with
  explicit ones ('{0} {1} ...').
- Implement cqlengine.functions.get_total_seconds() as alternative to
  timedelta.total_seconds().

cqlengine integration tests remain to be backported.

Subject: [PATCH 2295/4528] Refactor socket creation to Connection base

PYTHON-322
Fixes an issue where AsyncoreConnection could not be used with SSL in
Python 2.6 (ssl did not implement connect_ex).
Refactored socket connect to common routine, and simplified
AsyncoreConnection by using that and initializing the dispatcher with
the connected socket.
Also adds ssl support to EventletConnection.

Subject: [PATCH 2307/4528] Set models.DEFAULT_KEYSPACE when calling
 set_session()

Sets the default keyspace for cqlengine models when passing in an
existing session to cqlengine.connection.set_session() if the session's
keyspace is set and models.DEFAULT_KEYSPACE isn't. Without this, the
user will see an error when trying to perform Cassandra interactions
with a Model instance like "Keyspace none does not exist" unless they
explicitly set models.DEFAULT_KEYSPACE themselves ahead of time or have
a __keyspace__ attribute set on the model.
Also no longer raising an exception in cqlengine.connection.setup() if
default_keyspace isn't set since individual models might still have
__keyspace__ set.

Subject: [PATCH 2322/4528] For meta export, don't copy in default min/max
 compaction thresholds

Fixes an issue where table meta export would contain min/max_threshold
settings, even for compaction strategies that do not accept those.
Resulting CQL would cause "ConfigurationException ... code=2300 ...
Properties specified [min_threshold, max_threshold] are not
understood by [some compaction strategy]"

Subject: [PATCH 2325/4528] cqle: Update invalid inet test with a string that
 won't parse

Cassandra seems to be accepting various bad strings and inserting
'92.242.140.2' (for many different strings). Need to follow up on that.
Meanwhile, this string does induce an Invalid request.

Side note: I'm not sure this test is worth having, unless there is
supposed to be some kind of local validation. We're not testing the
server here.

Changes in anticipation of supporting modernized schema tables
(CASSANDRA-6717)

- schema change response/events normalized according to protocol spec
  keywords
-- events propagate with intrinsic keywords
- Parsing is defined by connection server version
- option to specialize query/parsing by earlier server versions (not
  implemented -- currently just refactored current conditional logic)

From c7690aaefa5e90e71576740f2a008e183fc32513 Mon Sep 17 00:00:00 2001
From: Adam Holmberg <Adam.Holmberg@datastax.com>
Date: Wed, 1 Jul 2015 14:14:05 -0500
Subject: [PATCH 2331/4528] Don't use change_type in schema refresh.

Was hoping to use change_type to avoid a query on DROPPED. However, this
introduces issues when the async drop event coincides with a create or
updatee on the same schema element.

Always querying makes sure the refresh sees the new element, assuming
schema agreement wait is enabled.

Subject: [PATCH 2342/4528] Make tox unit tests run from alternate directory

Ensures that build, installed extensions are used, instead of relying on
what is inplace for the package under test.

This allows us to test differing combinations of optional extensions
(cython) without any assumptions about the local package state.

Also:
- consolidate py26 section and place unittest2 as conditional dep
- introduce conditional cython dep, based on env var

Events are mostly processed in order. "mostly" because there is still a
race by way of the cluster thread pool executor. Meta class should be
robust against this.

 =================
 The Python driver for Cassandra offers several methods for executing queries.
 You can synchronously block for queries to complete using
-:meth:`.Session.execute()`, you can use a future-like interface through
-:meth:`.Session.execute_async()`, or you can attach a callback to the future
-with :meth:`.ResponseFuture.add_callback()`.  Each of these methods has
-different performance characteristics and behaves differently when
-multiple threads are used.
+:meth:`.Session.execute()`, you can obtain asynchronous request futures through
+:meth:`.Session.execute_async()`, and you can attach a callback to the future
+with :meth:`.ResponseFuture.add_callback()`.
 
-Benchmark Notes
----------------
-All benchmarks were executed using the
-`benchmark scripts <https://github.com/datastax/python-driver/tree/master/benchmarks>`_
-in the driver repository.  They were executed on a laptop with 16 GiB of RAM, an SSD,
-and a 2 GHz, four core CPU with hyper-threading.  The Cassandra cluster was a three
-node `ccm <https://github.com/pcmanus/ccm>`_ cluster running on the same laptop
-with version 1.2.13 of Cassandra. I suggest testing these benchmarks against your
-own cluster when tuning the driver for optimal throughput or latency.
-
-The 1.0.0 version of the driver was used with all default settings.  For these
-benchmarks, the driver was configured to use the ``libev`` reactor.  You can also run
-the benchmarks using the ``asyncore`` event loop (:class:`~.AsyncoreConnection`) 
-by using the ``--asyncore-only`` command line option. 
-
-Each benchmark completes 100,000 small inserts. The replication factor for the
-keyspace was three, so all nodes were replicas for the inserted rows.
-
-The benchmarks require the Python driver C extensions as well as a few additional 
-Python packages. Follow these steps to install the prerequisites:
-
-1. Install packages to support Python driver C extensions:
-
-   * Debian/Ubuntu: ``sudo apt-get install gcc python-dev libev4 libev-dev``
-   * RHEL/CentOS/Fedora: ``sudo yum install gcc python-dev libev4 libev-dev``
-
-2. Install Python packages: ``pip install scales twisted blist``
-3. Re-install the Cassandra driver: ``pip install --upgrade cassandra-driver``
-
-Synchronous Execution (`sync.py <https://github.com/datastax/python-driver/blob/master/benchmarks/sync.py>`_)
--------------------------------------------------------------------------------------------------------------
-Although this is the simplest way to make queries, it has low throughput
-in single threaded environments.  This is basically what the benchmark
-is doing:
-
-.. code-block:: python
-
-    from cassandra.cluster import Cluster
-
-    cluster = Cluster([127.0.0.1, 127.0.0.2, 127.0.0.3])
-    session = cluster.connect()
-
-    for i in range(100000):
-        session.execute("INSERT INTO mykeyspace.mytable (key, b, c) VALUES (a, 'b', 'c')")
-
-.. code-block:: bash
-
-    ~/python-driver $ python benchmarks/sync.py -n 100000 --hosts=127.0.0.1,127.0.0.2,127.0.0.3 --libev-only --threads=1
-    Average throughput: 434.08/sec
-
-
-This technique does scale reasonably well as we add more threads:
-
-.. code-block:: bash
-
-    ~/python-driver $ python benchmarks/sync.py -n 100000 --hosts=127.0.0.1,127.0.0.2,127.0.0.3 --libev-only --threads=2
-    Average throughput: 830.49/sec
-    ~/python-driver $ python benchmarks/sync.py -n 100000 --hosts=127.0.0.1,127.0.0.2,127.0.0.3 --libev-only --threads=4
-    Average throughput: 1078.27/sec
-    ~/python-driver $ python benchmarks/sync.py -n 100000 --hosts=127.0.0.1,127.0.0.2,127.0.0.3 --libev-only --threads=8
-    Average throughput: 1275.20/sec
-    ~/python-driver $ python benchmarks/sync.py -n 100000 --hosts=127.0.0.1,127.0.0.2,127.0.0.3 --libev-only --threads=16
-    Average throughput: 1345.56/sec
-
-
-In my environment, throughput is maximized at about 20 threads.
-
-
-Batched Futures (`future_batches.py <https://github.com/datastax/python-driver/blob/master/benchmarks/future_batches.py>`_)
----------------------------------------------------------------------------------------------------------------------------
-This is a simple way to work with futures for higher throughput.  Essentially,
-we start 120 queries asynchronously at the same time and then wait for them
-all to complete. We then repeat this process until all 100,000 operations
-have completed:
-
-.. code-block:: python
-
-    futures = Queue.Queue(maxsize=121)
-    for i in range(100000):
-        if i % 120 == 0:
-            # clear the existing queue
-            while True:
-                try:
-                    futures.get_nowait().result()
-                except Queue.Empty:
-                    break
-
-        future = session.execute_async(query)
-        futures.put_nowait(future)
-
-As expected, this improves throughput in a single-threaded environment:
-
-.. code-block:: bash
-
-    ~/python-driver $ python benchmarks/future_batches.py -n 100000 --hosts=127.0.0.1,127.0.0.2,127.0.0.3 --libev-only --threads=1
-    Average throughput: 3477.56/sec
-
-However, adding more threads may actually harm throughput:
-
-.. code-block:: bash
-
-    ~/python-driver $ python benchmarks/future_batches.py -n 100000 --hosts=127.0.0.1,127.0.0.2,127.0.0.3 --libev-only --threads=2
-    Average throughput: 2360.52/sec
-    ~/python-driver $ python benchmarks/future_batches.py -n 100000 --hosts=127.0.0.1,127.0.0.2,127.0.0.3 --libev-only --threads=4
-    Average throughput: 2293.21/sec
-    ~/python-driver $ python benchmarks/future_batches.py -n 100000 --hosts=127.0.0.1,127.0.0.2,127.0.0.3 --libev-only --threads=8
-    Average throughput: 2244.85/sec
-
-
-Queued Futures (`future_full_pipeline.py <https://github.com/datastax/python-driver/blob/master/benchmarks/future_full_pipeline.py>`_)
---------------------------------------------------------------------------------------------------------------------------------------
-This pattern is similar to batched futures.  The main difference is that
-every time we put a future on the queue, we pull the oldest future out
-and wait for it to complete:
-
-.. code-block:: python
-
-        futures = Queue.Queue(maxsize=121)
-        for i in range(100000):
-            if i >= 120:
-                old_future = futures.get_nowait()
-                old_future.result()
-
-            future = session.execute_async(query)
-            futures.put_nowait(future)
-
-This gets slightly better throughput than the Batched Futures pattern:
-
-.. code-block:: bash
+Examples of multiple request patterns can be found in the benchmark scripts included in the driver project.
 
-    ~/python-driver $ python benchmarks/future_full_pipeline.py -n 100000 --hosts=127.0.0.1,127.0.0.2,127.0.0.3 --libev-only --threads=1
-    Average throughput: 3635.76/sec
+The choice of execution pattern will depend on the application context. For applications dealing with multiple
+requests in a given context, the recommended pattern is to use concurrent asynchronous
+requests with callbacks. For many use cases, you don't need to implement this pattern yourself.
+:meth:`cassandra.concurrent.execute_concurrent` and :meth:`cassandra.concurrent.execute_concurrent_with_args`
+provide this pattern with a synchronous API and tunable concurrency.
 
-But this has the same throughput issues when multiple threads are used:
-
-.. code-block:: bash
-
-    ~/python-driver $ python benchmarks/future_full_pipeline.py -n 100000 --hosts=127.0.0.1,127.0.0.2,127.0.0.3 --libev-only --threads=2
-    Average throughput: 2213.62/sec
-    ~/python-driver $ python benchmarks/future_full_pipeline.py -n 100000 --hosts=127.0.0.1,127.0.0.2,127.0.0.3 --libev-only --threads=4
-    Average throughput: 2707.62/sec
-    ~/python-driver $ python benchmarks/future_full_pipeline.py -n 100000 --hosts=127.0.0.1,127.0.0.2,127.0.0.3 --libev-only --threads=8
-    Average throughput: 2462.42/sec
-
-Unthrottled Futures (`future_full_throttle.py <https://github.com/datastax/python-driver/blob/master/benchmarks/future_full_throttle.py>`_)
--------------------------------------------------------------------------------------------------------------------------------------------
-What happens if we don't throttle our async requests at all?
-
-.. code-block:: python
-
-    futures = []
-    for i in range(100000):
-        future = session.execute_async(query)
-        futures.append(future)
-
-    for future in futures:
-        future.result()
-
-Throughput is about the same as the previous pattern, but a lot of memory will
-be consumed by the list of Futures:
-
-.. code-block:: bash
-
-    ~/python-driver $ python benchmarks/future_full_throttle.py -n 100000 --hosts=127.0.0.1,127.0.0.2,127.0.0.3 --libev-only --threads=1
-    Average throughput: 3474.11/sec
-    ~/python-driver $ python benchmarks/future_full_throttle.py -n 100000 --hosts=127.0.0.1,127.0.0.2,127.0.0.3 --libev-only --threads=2
-    Average throughput: 2389.61/sec
-    ~/python-driver $ python benchmarks/future_full_throttle.py -n 100000 --hosts=127.0.0.1,127.0.0.2,127.0.0.3 --libev-only --threads=4
-    Average throughput: 2371.75/sec
-    ~/python-driver $ python benchmarks/future_full_throttle.py -n 100000 --hosts=127.0.0.1,127.0.0.2,127.0.0.3 --libev-only --threads=8
-    Average throughput: 2165.29/sec
-
-Callback Chaining (`callback_full_pipeline.py <https://github.com/datastax/python-driver/blob/master/benchmarks/callback_full_pipeline.py>`_)
------------------------------------------------------------------------------------------------------------------------------------------------
-This pattern is very different from the previous patterns.  Here we're taking
-advantage of the :meth:`.ResponseFuture.add_callback()` function to start
-another request as soon as one finishes.  Furthermore, we're starting 120
-of these callback chains, so we've always got about 120 operations in
-flight at any time:
-
-.. code-block:: python
-
-    from itertools import count
-    from threading import Event
-
-    sentinel = object()
-    num_queries = 100000
-    num_started = count()
-    num_finished = count()
-    finished_event = Event()
-
-    def insert_next(previous_result=sentinel):
-        if previous_result is not sentinel:
-            if isinstance(previous_result, BaseException):
-                log.error("Error on insert: %r", previous_result)
-            if num_finished.next() >= num_queries:
-                finished_event.set()
-
-        if num_started.next() <= num_queries:
-            future = session.execute_async(query)
-            # NOTE: this callback also handles errors
-            future.add_callbacks(insert_next, insert_next)
-
-    for i in range(min(120, num_queries)):
-        insert_next()
-
-    finished_event.wait()
-
-This is a more complex pattern, but the throughput is excellent:
-
-.. code-block:: bash
-
-    ~/python-driver $ python benchmarks/callback_full_pipeline.py -n 100000 --hosts=127.0.0.1,127.0.0.2,127.0.0.3 --libev-only --threads=1
-    Average throughput: 7647.30/sec
-
-Part of the reason why performance is so good is that everything is running on
-single thread: the internal event loop thread that powers the driver.  The
-downside to this is that adding more threads doesn't improve anything:
-
-.. code-block:: bash
-
-    ~/python-driver $ python benchmarks/callback_full_pipeline.py -n 100000 --hosts=127.0.0.1,127.0.0.2,127.0.0.3 --libev-only --threads=2
-    Average throughput: 7704.58/sec
-
-
-What happens if we have more than 120 callback chains running?
-
-With 250 chains:
-
-.. code-block:: bash
-
-    ~/python-driver $ python benchmarks/callback_full_pipeline.py -n 100000 --hosts=127.0.0.1,127.0.0.2,127.0.0.3 --libev-only --threads=1
-    Average throughput: 7794.22/sec
-
-Things look pretty good with 250 chains.  If we try 500 chains, we start to max out
-all of the connections in the connection pools.  The problem is that the current
-version of the driver isn't very good at throttling these callback chains, so
-a lot of time gets spent waiting for new connections and performance drops
-dramatically:
-
-.. code-block:: bash
-
-    ~/python-driver $ python benchmarks/callback_full_pipeline.py -n 100000 --hosts=127.0.0.1,127.0.0.2,127.0.0.3 --libev-only --threads=1
-    Average throughput: 679.61/sec
-
-When :attr:`.Cluster.protocol_version` is set to 1 or 2, you should limit the
-number of callback chains you run to roughly 100 per node in the cluster.
-When :attr:`~.Cluster.protocol_version` is 3 or higher, you can safely experiment
-with higher numbers of callback chains.
-
-For many use cases, you don't need to implement this pattern yourself.  You can
-simply use :meth:`cassandra.concurrent.execute_concurrent` and
-:meth:`cassandra.concurrent.execute_concurrent_with_args`, which implement
-this pattern for you with a synchronous API.
+Due to the GIL and limited concurrency, the driver can become CPU-bound pretty quickly. The sections below
+discuss further runtime and design considerations for mitigating this limitation.
 
 PyPy
 ----
-Almost all of these patterns become CPU-bound pretty quickly with CPython, the
-normal implementation of python. `PyPy <http://pypy.org>`_ is an alternative
-implementation of Python (written in Python) which uses a JIT compiler to
-reduce CPU consumption.  This leads to a huge improvement in the driver
-performance:

-.. code-block:: bash
+Cython Extensions
+-----------------
+`Cython <http://cython.org/>`_ is an optimizing compiler and language that can be used to compile the core files and
+optional extensions for the driver. Cython is not a strict dependency, but the extensions will be built by default
+if cython is present in the python path. To include Cython as a requirement, invoke with the extra name ``cython``:
 
-    ~/python-driver $ pypy benchmarks/callback_full_pipeline.py -n 500000 --hosts=127.0.0.1,127.0.0.2,127.0.0.3 --asyncore-only --threads=1
-    Average throughput: 18782.00/sec
+.. code-block:: bash
 
-Eventually the driver may add C extensions to reduce CPU consumption, which
-would probably narrow the gap between the performance of CPython and PyPy.

Subject: [PATCH 2410/4528] First attempt at fixing previous value tracking.

I reused the global '_is_persisted' flag on models to tell the value
manager about the origin of the previous value. Previous value is kept
aligned to the provided value only if the model instance is persisted,
else it is reset to None.

If I succeed, I propose to rename 'previous_value' to 'persisted_value'
then.

Subject: [PATCH 2418/4528] At pool level, only signal connection failure once
 per connection

Makes defuncting more efficient when there are many concurrent requests.

Also corrects signalling semantics - only accrue one connection error
per instance (not one per requests * instance).

+Faster Deserialization
+----------------------
+When python-driver is compiled with Cython, it uses a Cython-based deserialization path
+to deserialize messages. There are two additional ProtocolHandler classes that can be
+used to deserialize response messages: the first is ``LazyProtocolHandler`` and the
+second is ``NumpyProtocolHandler``.They can be used as follows:
+
+.. code:: python
+
+    from cassandra.protocol import NumpyProtocolHandler, LazyProtocolHandler
+    s.client_protocol_handler = LazyProtocolHandler   # for a result iterator
+    s.client_protocol_handler = NumpyProtocolHandler  # for a dict of NumPy arrays as result
+

Subject: [PATCH 2493/4528] Do not del libev IO wrappers while thread is still
 running

fixes an issue where the runtime would occasionally segfault when
exiting without cluster shutdown. This is because the IO object was
deacllocated while the thread was running and might still enter the IO
callback.

+Windows Installation Notes
+--------------------------
+Installing the driver with extensions in Windows sometimes presents some challenges. A few notes about common
+hang-ups:
+
+Setup requires a compiler. When using Python 2, this is as simple as installing `this package <http://aka.ms/vcpython27>`_
+(this link is also emitted during install if setuptools is unable to find the resources it needs). Depending on your
+system settings, this package may install as a user-specific application. Make sure to install for everyone, or at least
+as the user that will be building the Python environment.
+
+It is also possible to run the build with your compiler of choice. Just make sure to have your environment setup with
+the proper paths. Make sure the compiler target architecture matches the bitness of your Python runtime.
+Perhaps the easiest way to do this is to run the build/install from a Visual Studio Command Prompt (a
+shortcut installed with Visual Studio that sources the appropriate environment and presents a shell).

+Cython-based Extensions
+~~~~~~~~~~~~~~~~~~~~~~~
+By default, this package uses `Cython <http://cython.org/>`_ to optimize core modules and build custom extensions.
+This is not a hard requirement, but is engaged by default to build extensions offering better performance than the

-        By default, the :attr:`~.default_timeout` for the :class:`.Session`
-        this was created through will be used for the timeout on this
-        operation.
-
-        This timeout applies to the entire request, including any retries
-        (decided internally by the :class:`.policies.RetryPolicy` used with
-        the request).
+        yet, this method will block until it is set, or the timeout
+        set for the request expires.
 
+        Timeout is specified in the Session request execution functions.
         If the timeout is exceeded, an :exc:`cassandra.OperationTimedOut` will be raised.
         This is a client-side timeout. For more information
         about server-side coordinator timeouts, see :class:`.policies.RetryPolicy`.

-Cassandra can store entire collections within a column.  One of those
-collection types is a set.  Cassandra's sets are actually ordered
-sets.  By default, the driver will use a pure Python ordered sets to represent
-these collections.  If you would like to use an optimized implementation,

+Upgrading to 3.0
+----------------
+Version 3.0 of the DataStax Python driver for Apache Cassandra
+adds support for Cassandra 3.0 while maintaining support for
+all earlier versions. In addition to substantial internal rework,
+there are several updates to the API that integrators will need
+to consider:
+
+Default consistency is now ``LOCAL_QUORUM``
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Previous value was ``ONE``. ``ONE`` (or ``LOCAL_ONE``) is still appropriate for
+many applications, but the new default was chosen to be least surprising for
+new users not specifying a consistency level.
+
+Execution API Updates
+^^^^^^^^^^^^^^^^^^^^^
+Result return normalization
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+`PYTHON-368 <https://datastax-oss.atlassian.net/browse/PYTHON-368>`_
+Previously results would be returned as a ``list`` of rows for result rows
+up to ``fetch_size``, and ``PagedResult`` afterward. This could break
+application code that assumed one type and got another.
+
+Now, all results are returned as an iterable :class:`~.ResultSet`.
+
+The preferred way to consume results of unknown size is to iterate through
+them, letting automatic paging occur as they are consumed.
+
+.. code-block:: python
+
+    results = session.execute("SELECT * FROM system.local")
+    for row in results:
+        process(row)
+
+If the expected size of the results is known, it is still possible to
+materialize a list using the iterator:
+
+.. code-block:: python
+
+    results = session.execute("SELECT * FROM system.local")
+    row_list = list(results)
+
+For backward compatability, :class:`~.ResultSet` supports indexing. If
+the result is paged, all pages will be materialized. A warning will
+be logged if a paged query is implicitly materialized.
+
+Trace information is not attached to executed Statements
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+`PYTHON-318 <https://datastax-oss.atlassian.net/browse/PYTHON-318>`_
+Previously trace data was attached to Statements if tracing was enabled. This
+could lead to confusion if the same statement was used for multiple executions.
+
+Now, trace data is associated with the ``ResponseFuture`` and ``ResultSet``
+returned for each query:
+
+:meth:`.ResponseFuture.get_query_trace()`
+
+:meth:`.ResponseFuture.get_all_query_traces()`
+
+:meth:`.ResultSet.get_query_trace()`
+
+:meth:`.ResultSet.get_all_query_traces()`
+
+Binding named parameters now ignores extra names
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+`PYTHON-178 <https://datastax-oss.atlassian.net/browse/PYTHON-178Cassadfasdf>`_
+Previously, :meth:`.BoundStatement.bind()` would raise if a mapping
+was passed with extra names not found in the prepared statement.
+
+Behavior in 3.0+ is to ignore extra names.
+
+blist removed as soft dependency
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+`PYTHON-385 <https://datastax-oss.atlassian.net/browse/PYTHON-385>`_
+Previously the driver had a soft dependency on ``blist sortedset``, using
+that where available and using an internal fallback where possible.
+
+Now, the driver never chooses the ``blist`` variant, instead returning the
+internal :class:`.util.SortedSet` for all ``set`` results. The class implements
+all standard set operations, so no integration code should need to change unless
+it explicitly checks for ``sortedset`` type.
+
+Metadata API Updates
+^^^^^^^^^^^^^^^^^^^^
+`PYTHON-276 <https://datastax-oss.atlassian.net/browse/PYTHON-276>`_, `PYTHON-408 <https://datastax-oss.atlassian.net/browse/PYTHON-408>`_, `PYTHON-400 <https://datastax-oss.atlassian.net/browse/PYTHON-400>`_, `PYTHON-422 <https://datastax-oss.atlassian.net/browse/PYTHON-422>`_
+
+Cassandra 3.0 brought a substantial overhaul to the internal schema metadata representation.
+This version of the driver supports that metadata in addition to the legacy version. Doing so
+also brought some changes to the metadata model.
+
+The present API is documented: :any:`cassandra.metadata`. Changes highlighted below:
+
+* All types are now exposed as CQL types instead of types derived from the internal server implementation
+* Some metadata attributes have changed names to match current nomenclature (for example, :attr:`.Index.kind` in place of ``Index.type``).
+* Some metadata attributes removed
+
+  * ``TableMetadata.keyspace`` reference replaced with :attr:`.TableMetadata.keyspace_name`
+  * ``ColumnMetadata.index`` is removed table- and keyspace-level mappings are still maintained
+
+Several deprecated features are removed
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+`PYTHON-292 <https://datastax-oss.atlassian.net/browse/PYTHON-292>`_
+
+* ``ResponseFuture.result`` timeout parameter is removed, use ``Session.execute`` timeout instead (`031ebb0 <https://github.com/datastax/python-driver/commit/031ebb0>`_)
+* ``Cluster.refresh_schema`` removed, use ``Cluster.refresh_*_metadata`` instead (`419fcdf <https://github.com/datastax/python-driver/commit/419fcdf>`_)
+* ``Cluster.submit_schema_refresh`` removed (`574266d <https://github.com/datastax/python-driver/commit/574266d>`_)
+* ``cqltypes`` time/date functions removed, use ``util`` entry points instead (`bb984ee <https://github.com/datastax/python-driver/commit/bb984ee>`_)
+* ``decoder`` module removed (`e16a073 <https://github.com/datastax/python-driver/commit/e16a073>`_)
+* ``TableMetadata.keyspace`` attribute replaced with ``keyspace_name`` (`cc94073 <https://github.com/datastax/python-driver/commit/cc94073>`_)
+* ``cqlengine.columns.TimeUUID.from_datetime`` removed, use ``util`` variant instead (`96489cc <https://github.com/datastax/python-driver/commit/96489cc>`_)
+* ``cqlengine.columns.Float(double_precision)`` parameter removed, use ``columns.Double`` instead (`a2d3a98 <https://github.com/datastax/python-driver/commit/a2d3a98>`_)
+* ``cqlengine`` keyspace management functions are removed in favor of the strategy-specific entry points (`4bd5909 <https://github.com/datastax/python-driver/commit/4bd5909>`_)
+* ``cqlengine.Model.__polymorphic_*__`` attributes removed, use ``__discriminator*`` attributes instead (`9d98c8e <https://github.com/datastax/python-driver/commit/9d98c8e>`_)
+* ``cqlengine.statements`` will no longer warn about list list prepend behavior (`79efe97 <https://github.com/datastax/python-driver/commit/79efe97>`_)

+Packaging for Cassandra
+=======================
+A source distribution is included in Cassandra, which uses the driver internally for ``cqlsh``.
+To package a released version, checkout the tag and build a source zip archive::
+
+    python setup.py sdist --formats=zip
+
+If packaging a pre-release (untagged) version, it is useful to include a commit hash in the archive
+name to specify the built version::
+
+    python setup.py egg_info -b-`git rev-parse --short HEAD` sdist --formats=zip
+
+The file (``dist/cassandra-driver-<version spec>.zip``) is packaged with Cassandra in ``cassandra/lib/cassandra-driver-internal-only*zip``.

 This is not a hard requirement, but is engaged by default to build extensions offering better performance than the
 pure Python implementation.
 
+This is a costly build phase, especially in clean environments where the Cython compiler must be built
 This build phase can be avoided using the build switch, or an environment variable::
 
     python setup.py install --no-cython
-    -or-
-    pip install --install-option="--no-cython" <spec-or-path>
 
 Alternatively, an environment variable can be used to switch this option regardless of
 context::
 
     CASS_DRIVER_NO_CYTHON=1 <your script here>
+    - or, to disable all extensions:
+    CASS_DRIVER_NO_EXTENSIONS=1 <your script here>
+
+This method is required when using pip, which provides no other way of injecting user options in a single command::
+
+    CASS_DRIVER_NO_CYTHON=1 pip install cassandra-driver
+    CASS_DRIVER_NO_CYTHON=1 sudo -E pip install ~/python-driver
+
+The environment variable is the preferred option because it spans all invocations of setup.py, and will
+prevent Cython from being materialized as a setup requirement.
+
+If your sudo configuration does not allow SETENV, you must push the option flag down via pip. However, pip
+applies these options to all dependencies (which break on the custom flag). Therefore, you must first install
+dependencies, then use install-option::
+
+    sudo pip install six futures
+    sudo pip install --install-option="--no-cython"

Subject: [PATCH 2749/4528] Added PreparedGraphStatement and
 BoundGraphStatement classes.

- Once DSE Graph adds the possibility to prepare Gremlin queries, these classes should allow preparing, binding and executing binded statements. Tested with a sort of mock prepared statement, the behaviour of Prepared and BoundGraphStatements is validated in the sense that they serialize the parameters in the expected way defined in the specs, and returns results of the executions.
- Minor GraphResultSet method signature change.

+# New API for Python Driver's DSEGraph integration
+
+## GraphSession
+
+#### constructor
+- parameters: `Session` mandatory, `default_graph_options` optional.
+
+#### public fields
+ - `default_graph_options`, dictionary initialised with the default graph options defined in the specs. Options can be overriten or other added.
+- `session`, the wrapped `cassandra.cluster.Session`.
+
+#### exposed methods
+ - `execute()` takes arguments as either a `GraphStatement` or `BoundGraphStatement` or a query string, to execute it *synchronously* against the DSE cluster. Returns a `GraphResultSet` object containing the results of the execution.
+ - `prepare()` takes in argument a `GraphStatement` or a query string, and prepares it against the DSE instance. Returns a `PreparedGraphStatement`.
+
+##### private fields
+_None_
+
+
+
+## AbstractGraphStatement
+
+_Is not supposed to be directly used by users, is not part of the public API. Whereas child implementations will be exposed._
+
+#### constructor
+- parameters: _None_
+
+#### public fields
+- `graph_options`, dictionary containing the graph options to use and to override from the default ones defined in the session.
+
+#### exposed methods
+_None_
+
+##### private fields
+- `_wrapped`, the wrapped driver's statement. It is not supposed to be modified by users but only used internally.
+
+
+
+## GraphStatement _[extends AbstractGraphStatement]_
+
+#### constructor
+- parameters: `query_string` mandatory, `graph_options` optional.
+
+#### public fields
+- inherited from `AbstractGraphStatement`
+- `graph_options`, used to override `GraphSession`'s default graph options, on a per-statement basis.
+
+#### exposed methods 
+
+_None_
+
+##### private fields
+- inherited from `AbstractGraphStatement`
+
+
+
+## PreparedGraphStatement
+
+#### constructor
+- not supposed to be used by users
+
+#### public fields 
+_None_
+
+#### exposed methods
+- `bind()`, binds the provided values, and creates a `BoundGraphStatement` instance. The values must be in a dictionary, meaning that all parameters must be named, an exception will be raised if it is not the case.
+
+##### private fields
+- `_prepared_statement`, the `cassandra.query.PreparedStatement` instance wrapped.
+- `_graph_statement`, the graph statement associated with this statement. Used to propagate the graph options to a `BoundGraphStatement` created from a `PreparedGraphStatement`.
+
+
+
+## BoundGraphStatement _[extends AbstractGraphStatement]_
+
+#### constructor
+- not supposed to be used by users.
+
+#### public fields
+- inherited from `AbstractGraphStatement`
+- `values`, the values to be bound with the statement and sent to the server.
+
+#### exposed methods
+- `bind()`, bind the values parameters to this `BoundGraphStatement` instance. The values must be in a dictionary, meaning that all parameters must be named, an exception will be raised if it is not the case.
+
+##### private fields:
+- inherited from `AbstractGraphStatement`
+- `_prepared_statement`, the `cassandra.query.PreparedStatement` tied to this `BoundGraphStatement`.
+- `_graph_statement`, the graph statement associated with this statement. Used to propagate the graph options to a `BoundGraphStatement` created from a `PreparedGraphStatement`.
+
+
+
+## GraphResultSet
+
+#### constructor
+- not supposed to be used by users.
+
+#### public fields 
+_None_
+
+#### exposed methods
+- `__iter__()`/`next()`, allows iteration in the set, in `for ... in ...` loops. And manual iteration. Each iteration produces and returns one `GraphTraversalResult`.
+- `__getitem__`, allows getting results by index as a array. Each indexed access will return a `GraphTraversalResult`.
+
+##### private fields
+ - `_wrapped_rs`, the wrapped `cassandra.cluster.ResultSet`.

-# New API for Python Driver's DSEGraph integration
-
-## GraphSession
-
-#### constructor
-- parameters: `Session` mandatory, `default_graph_options` optional.
-
-#### public fields
- - `default_graph_options`, dictionary initialised with the default graph options defined in the specs. Options can be overriten or other added.
-- `session`, the wrapped `cassandra.cluster.Session`.
-
-#### exposed methods
- - `execute()` takes arguments as either a `GraphStatement` or `BoundGraphStatement` or a query string, to execute it *synchronously* against the DSE cluster. Returns a `GraphResultSet` object containing the results of the execution.
- - `prepare()` takes in argument a `GraphStatement` or a query string, and prepares it against the DSE instance. Returns a `PreparedGraphStatement`.
-
-##### private fields

-## AbstractGraphStatement
-
-_Is not supposed to be directly used by users, is not part of the public API. Whereas child implementations will be exposed._

-
-#### constructor
-- parameters: `query_string` mandatory, `graph_options` optional.

-
-#### public fields 
-_None_
-
-#### exposed methods
-- `bind()`, binds the provided values, and creates a `BoundGraphStatement` instance. The values must be in a dictionary, meaning that all parameters must be named, an exception will be raised if it is not the case.
-
-##### private fields
-- `_prepared_statement`, the `cassandra.query.PreparedStatement` instance wrapped.
-- `_graph_statement`, the graph statement associated with this statement. Used to propagate the graph options to a `BoundGraphStatement` created from a `PreparedGraphStatement`.

-## BoundGraphStatement _[extends AbstractGraphStatement]_
-
-#### constructor
-- not supposed to be used by users.
-
-#### public fields

-
-#### exposed methods
-- `bind()`, bind the values parameters to this `BoundGraphStatement` instance. The values must be in a dictionary, meaning that all parameters must be named, an exception will be raised if it is not the case.
-
-##### private fields:
-- inherited from `AbstractGraphStatement`
-- `_prepared_statement`, the `cassandra.query.PreparedStatement` tied to this `BoundGraphStatement`.

-
-## GraphResultSet
-
-#### constructor
-- not supposed to be used by users.
-
-#### public fields 
-_None_
-
-#### exposed methods
-- `__iter__()`/`next()`, allows iteration in the set, in `for ... in ...` loops. And manual iteration. Each iteration produces and returns one `GraphTraversalResult`.
-- `__getitem__`, allows getting results by index as a array. Each indexed access will return a `GraphTraversalResult`.
-
-##### private fields
- - `_wrapped_rs`, the wrapped `cassandra.cluster.ResultSet`.

+Lightweight Transactions (Compare-and-set)
+==========================================
+
+Lightweight Transactions (LWTs) are mostly pass-through CQL for the driver. However,
+the server returns some specialized results indicating the outcome and optional state
+preceding the transaction.
+
+For pertinent execution parameters, see :attr:`.Statement.serial_consistency_level`.
+
+This section discusses working with specialized result sets returned by the server for LWTs,
+and how to work with them using the driver.
+
+
+Specialized Results
+-------------------
+The result returned from a LWT request is always a single row result. It will always have
+prepended a special column named ``[applied]``. How this value appears in your results depends
+on the row factory in use. See below for examples.
+
+The value of this ``[applied]`` column is boolean value indicating whether or not the transaction was applied.
+If ``True``, it is the only column in the result. If ``False``, the additional columns depend on the LWT operation being
+executed:
+
+- When using a ``UPDATE ... IF "col" = ...`` clause, the result will contain the ``[applied]`` column, plus the existing columns
+  and values for any columns in the ``IF`` clause (and thus the value that caused the transaction to fail).
+
+- When using ``INSERT ... IF NOT EXISTS``, the result will contain the ``[applied]`` column, plus all columns and values
+  of the existing row that rejected the transaction.
+
+- ``UPDATE .. IF EXISTS`` never has additional columns, regardless of ``[applied]`` status.
+
+How the ``[applied]]`` column manifests depends on the row factory in use. Considering the following (initially empty) table::
+
+    CREATE TABLE test.t (
+        k int PRIMARY KEY,
+        v int,
+        x int
+    )
+
+... the following sections show the expected result for a number of example statements, using the three base row factories.
+
+named_tuple_factory (default)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The name ``[applied]`` is not a valid Python identifier, so the square brackets are actually removed
+from the attribute for the resulting ``namedtuple``. The row always has a boolean column ``applied`` in position 0::
+
+    >>> session.execute("INSERT INTO t (k,v) VALUES (0,0) IF NOT EXISTS")
+    Row(applied=True)
+
+    >>> session.execute("INSERT INTO t (k,v) VALUES (0,0) IF NOT EXISTS")
+    Row(applied=False, k=0, v=0, x=None)
+
+    >>> session.execute("UPDATE t SET v = 1, x = 2 WHERE k = 0 IF v =0")
+    Row(applied=True)
+
+    >>> session.execute("UPDATE t SET v = 1, x = 2 WHERE k = 0 IF v =0 AND x = 1")
+    Row(applied=False, v=1, x=2)
+
+tuple_factory
+~~~~~~~~~~~~~
+This return type does not refer to names, but the boolean value ``applied`` is always present in position 0::
+
+    >>> session.execute("INSERT INTO t (k,v) VALUES (0,0) IF NOT EXISTS")
+    (True,)
+
+    >>> session.execute("INSERT INTO t (k,v) VALUES (0,0) IF NOT EXISTS")
+    (False, 0, 0, None)
+
+    >>> session.execute("UPDATE t SET v = 1, x = 2 WHERE k = 0 IF v =0")
+    (True,)
+
+    >>> session.execute("UPDATE t SET v = 1, x = 2 WHERE k = 0 IF v =0 AND x = 1")
+    (False, 1, 2)
+
+dict_factory
+~~~~~~~~~~~~
+The retuned ``dict`` contains the ``[applied]`` key::
+
+    >>> session.execute("INSERT INTO t (k,v) VALUES (0,0) IF NOT EXISTS")
+    {u'[applied]': True}
+
+    >>> session.execute("INSERT INTO t (k,v) VALUES (0,0) IF NOT EXISTS")
+    {u'x': 2, u'[applied]': False, u'v': 1}
+
+    >>> session.execute("UPDATE t SET v = 1, x = 2 WHERE k = 0 IF v =0")
+    {u'x': None, u'[applied]': False, u'k': 0, u'v': 0}
+
+    >>> session.execute("UPDATE t SET v = 1, x = 2 WHERE k = 0 IF v =0 AND x = 1")
+    {u'[applied]': True}
+
+

Subject: [PATCH 2798/4528] mimic shapely.geometry type attributes in dse.util
 geo types

Changed DSE util types to have similar naming and composition to
the shapely library. This allows shapely types to be used interchangably
when serializing for binding. It also makes it more intuitive to init
one from the other.

Subject: [PATCH 2807/4528] Fix Python3 bug with Timers and heaps

Add comparison operator to allow Timers with the same end time to be
pushed into heaps. It's poorly documented, but the warning can be found
here:
https://docs.python.org/2/library/heapq.html#priority-queue-implementation-notes
"In the future with Python 3, tuple comparison breaks for (priority,
task) pairs if the priorities are equal and the tasks do not have a
default comparison order."

Subject: [PATCH 2858/4528] Fix Python3 bug with Timers and heaps

Add comparison operator to allow Timers with the same end time to be
pushed into heaps. It's poorly documented, but the warning can be found
here:
https://docs.python.org/2/library/heapq.html#priority-queue-implementation-notes
"In the future with Python 3, tuple comparison breaks for (priority,
task) pairs if the priorities are equal and the tasks do not have a
default comparison order."

Subject: [PATCH 2867/4528] Expose conflicting data in case of LWTException

Adds a custom attribute, `existing`, to the LWTException instance which
allows the application layer to inspect the values read from Cassandra
which conflicted with the attempted conditional write.

The documentation already referred to the `existing` attribute but it
was not implemented.

Subject: [PATCH 2872/4528] Fix hang when using eventlet and ssl

The eventlet read loop runs select before each recv call. This will
fail because recv() on an ssl socket might read more data than
requested from the underlying socket in order to have enough context
for decryption. These extra bytes would be returned by the next recv
on the ssl socket, but are not known to underlying socket so select
will hang.

It is my understanding that eventlet implements blocking IO by using
poll under the hood and yielding, so the select should not be
necessary at all

+Design and Implementation Guidelines
+------------------------------------
+- We support Python 2.6+, so any changes must work in any of these runtimes (we use ``six``, ``futures``, and some internal backports for compatability)
+- We have integrations (notably Cassandra cqlsh) that require pure Python and minimal external dependencies. We try to avoid new external dependencies. Where compiled extensions are concerned, there should always be a pure Python fallback implementation.
+- This project follows `semantic versioning <http://semver.org/>`_, so breaking API changes will only be introduced in major versions.
+- Legacy ``cqlengine`` has varying degrees of overreaching client-side validation. Going forward, we will avoid client validation where server feedback is adequate and not overly expensive.
+- When writing tests, try to achieve maximal coverage in unit tests (where it is faster to run across many runtimes). Integration tests are good for things where we need to test server interaction, or where it is important to test across different server versions (emulating in unit tests would not be effective).

+Working with Dates and Times
+============================
+
+This document is meant to provide on overview of the assumptions and limitations of the driver time handling, the
+reasoning behind it, and describe approaches to working with these types.
+
+timestamps (Cassandra DateType)
+-------------------------------
+
+Timestamps in Cassandra are timezone-naive timestamps encoded as microseconds since UNIX epoch. Clients working with
+timestamps in this database usually find it easiest to reason about them if they are always assumed to be UTC. To quote the
+pytz documentation, "The preferred way of dealing with times is to always work in UTC, converting to localtime only when
+generating output to be read by humans." The driver adheres to this tenant, and assumes UTC is always in the database. The
+driver attempts to make this correct on the way in, and assumes no timezone on the way out.
+
+Write Path
+~~~~~~~~~~
+When inserting timestamps, the driver handles serialization for the write path as follows:
+
+If the input is a ``datetime.datetime``, the serialization is normalized by starting with the ``utctimetuple()`` of the
+value.
+
+- If the ``datetime`` object is timezone-aware, the timestamp is shifted, and represents the UTC timestamp equivalent.
+- If the ``datetime`` object is timezone-naive, this results in no shift -- any ``datetime`` with no timezone information is assumed to be UTC
+
+Note the second point above applies even to "local" times created using ``now()``::
+
+    >>> d = datetime.now()
+
+    >>> print(d.tzinfo)
+    None
+
+
+These do not contain timezone information intrinsically, so they will be assumed to be UTC and not shifted. When generating
+timestamps in the application, it is clearer to use ``datetime.utcnow()`` to be explicit about it.
+
+If the input for a timestamp is numeric, it is assumed to be a epoch-relative microsecond timestamp, as specified in the
+CQL spec -- no scaling or conversion is done.
+
+Read Path
+~~~~~~~~~
+The driver always assumes persisted timestamps are UTC and makes no attempt to localize them. Returned values are
+timezone-naive ``datetime.datetime``. We follow this approach because the datetime API has deficiencies around daylight
+saving time, and the defacto package for handling this is a third-party package (we try to minimize external dependencies
+and not make decisions for the integrator).
+
+The decision for how to handle timezones is left to the application. For the most part it is straightforward to apply
+localization to the ``datetime``\s returned by queries. One prevalent method is to use pytz for localization::
+
+    import pytz
+    user_tz = pytz.timezone('US/Central')
+    timestamp_naive = row.ts
+    timestamp_utc = pytz.utc.localize(timestamp_naive)
+    timestamp_presented = timestamp_utc.astimezone(user_tz)
+
+This is the most robust approach (likely refactored into a function). If it is deemed too cumbersome to apply for all call
+sites in the application, it is possible to patch the driver with custom deserialization for this type. However, doing
+this depends depends some on internal APIs and what extensions are present, so we will only mention the possibility, and
+not spell it out here.
+
+date, time (Cassandra DateType)
+-------------------------------
+Date and time in Cassandra are idealized markers, much like ``datetime.date`` and ``datetime.time`` in the Python standard
+library. Unlike these Python implementations, the Cassandra encoding supports much wider ranges. To accommodate these
+ranges without overflow, this driver returns these data in custom types: :class:`.util.Date` and :class:`.util.Time`.
+
+Write Path
+~~~~~~~~~~
+For simple (not prepared) statements, the input values for each of these can be either a string literal or an encoded
+integer. See `Working with dates <https://github.com/apache/cassandra/blob/trunk/doc/cql3/CQL.textile#working-with-dates>`_
+or `Working with time <https://github.com/apache/cassandra/blob/trunk/doc/cql3/CQL.textile#working-with-time>`_ for details
+on the encoding or string formats.
+
+For prepared statements, the driver accepts anything that can be used to construct the :class:`.util.Date` or
+:class:`.util.Time` classes. See the linked API docs for details.
+
+Read Path
+~~~~~~~~~
+The driver always returns custom types for ``date`` and ``time``.
+
+The driver returns :class:`.util.Date` for ``date`` in order to accommodate the wider range of values without overflow.
+For applications working within the supported range of [``datetime.MINYEAR``, ``datetime.MAXYEAR``], these are easily
+converted to standard ``datetime.date`` insances using :meth:`.Date.date`.
+
+The driver returns :class:`.util.Time` for ``time`` in order to retain nanosecond precision stored in the database.
+For applications not concerned with this level of precision, these are easily converted to standard ``datetime.time``
+insances using :meth:`.Time.time`.

Subject: [PATCH 3165/4528] Don't modify the Metadatas' hosts structure while
 iterating over it

On Python 3.x, dict.values() returns a view object and not a list of the
values.
Updating the content of the original dict while iterating over the
values may raise a RuntimeError exception, which is the case in the
Cluster._refresh_node_list_and_token_map() method to remove discovered
hosts which are not part of the specified cluster contact points.

The bug doesn't happen using Python 2.x as dict.values() returns a new
list containing the values of the dictionary, without any other
reference to original dictionary object.

This fix forces the original Python 2.x behavior to be the same in
Python 3.x as well.

+Execution Profiles (experimental)
+=================================
+
+Execution profiles are an experimental API aimed at making it easier to execute requests in different ways within
+a single connected ``Session``. Execution profiles are being introduced the exploding number of configuration options,
+especially as the database platform evolves more complex workloads.
+
+The Execution Profile API is being introduced now, in an experimental capacity in order to take advantage of it in
+existing projects, and to guage interest and feedback in the community. For now, the legacy configuration remains
+intact, but legacy and Execution Profile APIs cannot be used simultaneously on the same client ``Cluster``.
+
+This document explains how Execution Profiles relate to existing settings, and shows how to use the new profiles for
+request execution.
+
+Mapping Legacy Parameters to Profiles
+-------------------------------------
+
+Execution profiles can inherit from :class:`.cluster.ExecutionProfile`, and currently provide the following options,
+previously input from the noted attributes:
+
+- load_balancing_policy - :attr:`.Cluster.load_balancing_policy`
+- request_timeout - :attr:`.Session.default_timeout`, optional :meth:`.Session.execute` parameter
+- retry_policy - :attr:`.Cluster.default_retry_policy`, optional :attr:`.Statement.retry_policy` attribute
+- consistency_level - :attr:`.Session.default_consistency_level`, optional :attr:`.Statement.consistency_level` attribute
+- serial_consistency_level - :attr:`.Session.default_serial_consistency_level`, optional :attr:`.Statement.serial_consistency_level` attribute
+- row_factory - :attr:`.Session.row_factory` attribute
+
+When using the new API, these parameters can be defined by instances of :class:`.cluster.ExecutionProfile`.
+
+Using Execution Profiles

+Note that, even when custom profiles are injected, the default ``TokenAwarePolicy(DCAwareRoundRobinPolicy())`` is still
+present. To override the default, specify a policy with the :data:`~.cluster.EXEC_PROFILE_DEFAULT` key.
+
+.. code:: python
+
+    from cassandra.cluster import EXEC_PROFILE_DEFAULT
+    profile = ExecutionProfile(request_timeout=30)
+    cluster = Cluster(execution_profiles={EXEC_PROFILE_DEFAULT: profile})
+
+
+Adding named profiles
+~~~~~~~~~~~~~~~~~~~~~
+
+New profiles can be added constructing from scratch, or deriving from default:
+
+.. code:: python
+
+    from cassandra.cluster import ExecutionProfile
+    from cassandra.policies import WhiteListRoundRobinPolicy
+    locked_execution = ExecutionProfile()
+    locked_execution.load_balancing_policy = WhiteListRoundRobinPolicy(['127.0.0.1'])
+    node1_profile = 'node1_whitelist'
+    cluster.add_execution_profile(node1_profile, locked_execution)
+    
+    for _ in cluster.metadata.all_hosts():
+        print session.execute(local_query, execution_profile=node1_profile)[0]
+
+
+.. parsed-literal::
+
+    Row(rpc_address='127.0.0.1')
+    Row(rpc_address='127.0.0.1')
+
+See :meth:`.Cluster.add_execution_profile` for details and optional parameters.
+
+Passing a profile instance without mapping
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+We also have the ability to pass profile instances to be used for execution, but not added to the mapping:
+
+.. code:: python
+
+    from copy import copy
+    from cassandra.query import tuple_factory
+    
+    tmp = copy(node1_profile)
+    tmp.request_timeout = 100
+    tmp.row_factory = tuple_factory
+    
+    print session.execute(local_query, execution_profile=tmp)[0]
+    print session.execute(local_query, execution_profile='node1')[0]
+
+.. parsed-literal::
+
+    ('127.0.0.1',)
+    Row(rpc_address='127.0.0.1')
+
+As shown above, the ``tmp`` profile shares a load balancing policy with one managed by the cluster. If this technique
+is not used, the application would need to initialize and maintain the policy state manually.
+

+Default TTL and Per Query TTL
+=============================
+
+Model default TTL now relies on the *default_time_to_live* feature, introduced in Cassandra 2.0. It is not handled anymore in the CQLEngine Model (cassandra-driver >=3.6). You can set the default TTL of a table like this:
+
+    Example:
+
+    .. code-block:: python
+
+        class User(Model):
+            __options__ = {'default_time_to_live': 20}
+
+            user_id = columns.UUID(primary_key=True)
+            ...
+
+You can set TTL per-query if needed. Here are a some examples:
+
+    Example:
+
+    .. code-block:: python
+
+        class User(Model):
+            __options__ = {'default_time_to_live': 20}
+
+            user_id = columns.UUID(primary_key=True)
+            ...
+
+        user = User.objects.create(user_id=1)  # Default TTL 20 will be set automatically on the server
+
+        user.ttl(30).update(age=21)            # Update the TTL to 30
+        User.objects.ttl(10).create(user_id=1)  # TTL 10
+        User(user_id=1, age=21).ttl(10).save()  # TTL 10
+
+

+using a `BATCH cql query <http://cassandra.apache.org/doc/cql3/CQL-3.0.html#batchStmt>`_.
 With version 2 of the native protocol, you can now batch statements at
 the protocol level. This allows you to use many different prepared
 statements within a single batch.

Subject: [PATCH 3391/4528] Add __len__ to BatchStatement

A __len__ method on BatchStatement would allow getting the length of the batch without poking around in the 'private' _statements_and_parameters field.

+==========================
+Connections (experimental)
+==========================
+
+Connections are experimental and aimed to ease the use of multiple sessions with cqlengine. Connections can be set on a model class, per query or using a context manager.
+
+
+Register a new connection
+=========================
+
+To use cqlengine, you need at least a default connection. This is currently done automatically under the hood with :func:`connection.setup <.connection.setup>`. If you want to use another cluster/session, you need to register a new cqlengine connection. You register a connection with :func:`~.connection.register_connection`
+
+    .. code-block:: python
+
+        from cassandra.cqlengine import connection
+
+        connection.setup(['127.0.0.1')
+        connection.register_connection('cluster2', ['127.0.0.2'])
+
+Change the default connection
+=============================
+
+You can change the default cqlengine connection on registration:
+
+    .. code-block:: python
+
+        from cassandra.cqlengine import connection
+
+        connection.register_connection('cluster2', ['127.0.0.2'] default=True)
+
+or on the fly using :func:`~.connection.set_default_connection`
+
+    .. code-block:: python
+
+        connection.set_default_connection('cluster2')
+
+Unregister a connection
+=======================
+
+You can unregister a connection using :func:`~.connection.unregister_connection`:
+
+    .. code-block:: python
+
+        connection.unregister_connection('cluster2')
+
+Management
+==========
+
+When using multiples connections, you also need to sync your models on all connections (and keyspaces) that you need operate on. Management commands have been improved to ease this part. Here is an example:
+
+    .. code-block:: python
+
+       from cassandra.cqlengine import management
+
+       keyspaces = ['ks1', 'ks2']
+       conns = ['cluster1', 'cluster2']
+
+       # registers your connections
+       # ...
+
+       # create all keyspaces on all connections
+       for ks in keyspaces:
+           management.create_simple_keyspace(ks, connections=conns)
+
+       # define your Automobile model
+       # ...
+
+       # sync your models
+       management.sync_table(Automobile, keyspaces=keyspaces, connections=conns)
+
+
+Connection Selection
+====================
+
+cqlengine will select the default connection, unless your specify a connection using one of the following methods.
+
+Default Model Connection
+------------------------
+
+You can specify a default connection per model:
+
+    .. code-block:: python
+
+        class Automobile(Model):
+            __keyspace__ = 'test'
+            __connection__ = 'cluster2'
+            manufacturer = columns.Text(primary_key=True)
+            year = columns.Integer(primary_key=True)
+            model = columns.Text(primary_key=True)
+
+        print len(Automobile.objects.all())  # executed on the connection 'cluster2'
+
+QuerySet and model instance
+---------------------------
+
+You can use the :attr:`using() <.query.ModelQuerySet.using>` method to select a connection (or keyspace):
+
+    .. code-block:: python
+
+        Automobile.objects.using(connection='cluster1').create(manufacturer='honda', year=2010, model='civic')
+        q = Automobile.objects.filter(manufacturer='Tesla')
+        autos = q.using(keyspace='ks2, connection='cluster2').all()
+
+        for auto in autos:
+            auto.using(connection='cluster1').save()
+
+Context Manager
+---------------
+
+You can use the ContextQuery as well to select a connection:
+
+    .. code-block:: python
+
+        with ContextQuery(Automobile, connection='cluster1') as A:
+            A.objects.filter(manufacturer='honda').all()  # executed on 'cluster1'
+
+
+BatchQuery
+----------
+
+With a BatchQuery, you can select the connection with the context manager. Note that all operations in the batch need to use the same connection.
+
+    .. code-block:: python
+
+        with BatchQuery(connection='cluster1') as b:
+            Automobile.objects.batch(b).create(manufacturer='honda', year=2010, model='civic')

+:func:`~.connection.register_connection` can take a list of hosts, as shown above, in which case it will create a connection with a new session. It can also take a `session` argument if you've already created a session:

+    .. code-block:: python
+
+        from cassandra.cqlengine import connection
+        from cassandra.cluster import Cluster
+
+        session = Cluster(['127.0.0.1']).connect()
+        connection.register_connection('cluster3', session=session)
+

Subject: [PATCH 3466/4528] cancel timers before defuncting connection

This allows us to revert some of the fix to PYTHON-367 without the timer
heap growing out of control as described on that ticket. We cancel
before defuncting to ensure that the timer doesn't hang around while
running callbacks. Between this change and the delegation of callbacks
to a secondary thread (see commit 51923029, part of the original
PYTHON-367 fix), this commit should not cause a regression on
PYTHON-367.

Note that we don't cancel timers before defuncting and retrying -- we're
not done with the logical request and still want that timer to fire.

Now that timers are started on ResponseFuture initialization, we
actually use the value of timeout in the tests, so we no longer pass
that argument, allowing the test to use the default value.

+Bug Fixes
+---------
+
+* Potential Timing issue if application exits prior to session pool initialization (PYTHON-636)
+* "Host X.X.X.X has been marked down" without any exceptions (PYTHON-640)
+* NoHostAvailable or OperationTimedOut when using execute_concurrent with a generator that inserts into more than one table (PYTHON-642)
+* ResponseFuture creates Timers and don't cancel them even when result is received which leads to memory leaks (PYTHON-644)
+* Driver cannot connect to Cassandra version > 3 (PYTHON-646)
+* Unable to import model using UserType without setuping connection since 3.7 (PYTHON-649)
+* Don't prepare queries on ignored hosts on_up (PYTHON-669)

Subject: [PATCH 3650/4528] remove eager callback execution in timer

With our fix for PYTHON-755, you can now start timers with a negative
timeout in cluster.Cluster._start_timer. When this happens,
Timer.callback can be called twice, once in Timer.__init__ and once in
Timer.finish. The first is just an optimization, so we remove it here.

+
+        Limitations:
+        - Currently, cqlengine does not support SASI index creation. To use this feature,
+          you need to create the SASI index using the core driver.
+        - Queries using LIKE must use allow_filtering() since the *model* column has no
+          standard secondary index. Note that the server will use the SASI index properly
+          when executing the query.

+Execution Profiles
+==================
 
-Execution profiles are an experimental API aimed at making it easier to execute requests in different ways within
+Execution profiles aim at making it easier to execute requests in different ways within
 a single connected ``Session``. Execution profiles are being introduced to deal with the exploding number of
 configuration options, especially as the database platform evolves more complex workloads.
 
-The Execution Profile API is being introduced now, in an experimental capacity, in order to take advantage of it in
-existing projects, and to gauge interest and feedback in the community. For now, the legacy configuration remains
-intact, but legacy and Execution Profile APIs cannot be used simultaneously on the same client ``Cluster``.
+The legacy configuration remains intact, but legacy and Execution Profile APIs
+cannot be used simultaneously on the same client ``Cluster``. Legacy configuration
+will be removed in the next major release (4.0).
 
 This document explains how Execution Profiles relate to existing settings, and shows how to use the new profiles for
 request execution.

Subject: [PATCH 3860/4528] always add to a random replica

Tested with `ccm create test-endpoints -n 5 -v 3.11.1` and the script
below. Against the previous implementation resulted in
length of each key looking something like this:
{<Host: 127.0.0.1 datacenter1>: 60188,
 <Host: 127.0.0.2 datacenter1>: 19878,
 <Host: 127.0.0.3 datacenter1>: 19934}

The new implementation's results look more like this:

{<Host: 127.0.0.1 datacenter1>: 19866,
 <Host: 127.0.0.2 datacenter1>: 20224,
 <Host: 127.0.0.3 datacenter1>: 19869,
 <Host: 127.0.0.4 datacenter1>: 20009,
 <Host: 127.0.0.5 datacenter1>: 20032}

What happens in the test (5 nodes, RF=3) is this: group_keys_by_replica
checks C* keys and adds them, preferring hosts that are already there,
until there are 3 hosts in keys_per_host. Once those 3 hosts are chosen,
no new hosts will be added -- with RF=3 across 5 nodes, every key is
guaranteed to map to >= 1 of the 3 hosts already in the map.

The new implementation distributes values more evenly.

+By default, installing the driver through ``pip`` uses Cython to compile
+certain parts of the driver.
+This makes those hot paths faster at runtime, but the Cython compilation

+:ref:`disable Cython as documented below <cython-extensions>`.
+You can also use ``CASS_DRIVER_BUILD_CONCURRENCY`` to increase the number of

+    $ # installing from pip
+    $ CASS_DRIVER_BUILD_CONCURRENCY=8 pip install cassandra-driver
+
+Finally, you can `build a wheel <https://packaging.python.org/tutorials/distributing-packages/#wheels>`_ from the driver's source and distribute that to computers
+that depend on it. For example:
+
+    $ git clone https://github.com/datastax/python-driver.git

Subject: [PATCH 3953/4528] PYTHON-1008

Addresses PYTHON-1008/CASSANDRA-14632.

The CREATE CUSTOM INDEX statement initially generated in
`IndexMetadata.as_cql_query` is always a `unicode` object under Python 2,
because they are derived from CQL `text` fields in in
`system_schema.indexes`, and we serialize the bytes we get from
`text`-type values with `.encode('utf-8')`.

The result of `cql_encode_all_types` is always a `six.binary_type`, i.e.
a `str` under Python 2.

Notably, Python 2 `str` objects cannot be cast to `unicode` objects if
they contain non-ASCII characters, including those used to encode
Unicode characters in UTF-8. These casting errors can occur during
attempts to concatenate these objects:

```
>>> u"I'm a `unicode` object" + ", and I am a `str`."
u"I'm a `unicode` object, and I am a `str`."
>>> u"I'm a `unicode` object" + ", and I am a `str` with unicode code points \xf0\x9f\x98\xac"
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
UnicodeDecodeError: 'ascii' codec can't decode byte 0xf0 in position 45: ordinal not in range(128)
```

So, the error reported in CASSANDRA-14632 happens when we try to
concatenate a `str` containing escaped UTF-8 bytes, as generated by
`cql_encode_all_types`, onto `ret`, a `unicode`.

Since we know `ret` is always a `six.text_type`, we can check if we need
to convert the result of `cql_encode_all_types`, and do so. We should
only ever need to under Python 2.

 Design and Implementation Guidelines
 ------------------------------------
-- We support Python 2.6+, so any changes must work in any of these runtimes (we use ``six``, ``futures``, and some internal backports for compatability)
+- We support Python 2.7+, so any changes must work in any of these runtimes (we use ``six``, ``futures``, and some internal backports for compatability)
 - We have integrations (notably Cassandra cqlsh) that require pure Python and minimal external dependencies. We try to avoid new external dependencies. Where compiled extensions are concerned, there should always be a pure Python fallback implementation.
 - This project follows `semantic versioning <http://semver.org/>`_, so breaking API changes will only be introduced in major versions.
 - Legacy ``cqlengine`` has varying degrees of overreaching client-side validation. Going forward, we will avoid client validation where server feedback is adequate and not overly expensive.

+With version 3.17.0 and higher, you will need to set :attr:`.Cluster.ssl_context` to a

 to a dict of options. These will be passed as kwargs to ``ssl.SSLContext.wrap_socket()``
 when new sockets are created.
 
-For example:
+The following examples assume you have generated your cassandra certificate and

+* `Using SSL in DSE drivers <https://docs.datastax.com/en/dse/6.7/dse-dev/datastax_enterprise/appDevGuide/sslDrivers.html>`_
+
+SSL Configuration Examples
+^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+No identity verification
+++++++++++++++++++++++++
+
+No identity verification at all. Note that this is not recommended for for production deployments.
+
+The cassandra configuration::
+
+    client_encryption_options:
+      enabled: true
+      keystore: /path/to/127.0.0.1.keystore
+      keystore_password: myStorePass
+      require_client_auth: false
+
+The driver configuration:
 
 .. code-block:: python
 
-    from cassandra.cluster import Cluster
+    from cassandra.cluster import Cluster, Session
+    from ssl import SSLContext, PROTOCOL_TLSv1
+
+    ssl_context = SSLContext(PROTOCOL_TLSv1)
+
+    cluster = Cluster(['127.0.0.1'], ssl_context=ssl_context)
+    session = cluster.connect()
+
+Client verifies server
+++++++++++++++++++++++
+
+Ensure the python driver verifies the identity of the server.
+
+The cassandra configuration::
+
+    client_encryption_options:
+      enabled: true
+      keystore: /path/to/127.0.0.1.keystore
+      keystore_password: myStorePass
+      require_client_auth: false
+
+For the driver configuration, it's very important to set `ssl_context.verify_mode`
+to `CERT_REQUIRED`. Otherwise, the loaded verify certificate will have no effect:
+
+.. code-block:: python
+
+    from cassandra.cluster import Cluster, Session
     from ssl import SSLContext, PROTOCOL_TLSv1, CERT_REQUIRED
 
     ssl_context = SSLContext(PROTOCOL_TLSv1)
+    ssl_context.load_verify_locations('/path/to/rootca.crt')
     ssl_context.verify_mode = CERT_REQUIRED
-    ssl_context.load_verify_locations('/path/to/my/ca.certs')
-    cluster = Cluster(ssl_context=ssl_context)
 
+    cluster = Cluster(['127.0.0.1'], ssl_context=ssl_context)
+    session = cluster.connect()
 
-This is only an example to show how to pass the ssl parameters. Consider reading
-the `python ssl documentation <https://docs.python.org/3/library/ssl.html#ssl.SSLContext>`_ for
-your configuration.
+Additionally, you can also verify the `hostname` of the server:
+
+.. code-block:: python
+
+    from cassandra.cluster import Cluster, Session
+    from ssl import SSLContext, PROTOCOL_TLSv1, CERT_REQUIRED
+
+    ssl_context = SSLContext(PROTOCOL_TLSv1)
+    ssl_context.load_verify_locations('/path/to/rootca.crt')
+    ssl_context.verify_mode = CERT_REQUIRED
+    ssl_context.check_hostname = True
+    ssl_options = {'server_hostname': '127.0.0.1'}
+
+    cluster = Cluster(['127.0.0.1'], ssl_context=ssl_context, ssl_options=ssl_options)
+    session = cluster.connect()
+
+Server verifies client
+++++++++++++++++++++++
+
+If cassandra is configured to verify clients (require_client_auth), you need to generate
+SSL key and certificate files for them.
+
+The cassandra configuration::
+
+    client_encryption_options:
+      enabled: true
+      keystore: /path/to/127.0.0.1.keystore
+      keystore_password: myStorePass
+      require_client_auth: true
+      truststore: /path/to/dse-truststore.jks
+      truststore_password: myStorePass
+
+For Python, you need to generate certificate in PEM format. First, create a certificate
+conf file:
+
+.. code-block:: bash
+
+    cat > gen_client_cert.conf <<EOF
+    [ req ]
+    distinguished_name = req_distinguished_name
+    prompt = no
+    output_password = ${ROOT_CERT_PASS}
+    default_bits = 2048
+
+    [ req_distinguished_name ]
+    C = ${CERT_COUNTRY}
+    O = ${CERT_ORG_NAME}
+    OU = ${CERT_OU}
+    CN = client
+    EOF
+
+Make sure you replaced the variables with the same values you used for the initial
+root CA certificate. Then, generate the key:
+
+.. code-block:: bash
+
+    openssl req -newkey rsa:2048 -nodes -keyout client.key -out client.csr -config gen_client_cert.conf
+
+And generate the client signed certificate:
+
+.. code-block:: bash
+
+    openssl x509 -req -CA ${ROOT_CA_BASE_NAME}.crt -CAkey ${ROOT_CA_BASE_NAME}.key -passin pass:${ROOT_CERT_PASS} \
+        -in client.csr -out client.crt_signed -days ${CERT_VALIDITY} -CAcreateserial
+
+The driver configuration:
+
+.. code-block:: python
+
+    from cassandra.cluster import Cluster, Session
+    from ssl import SSLContext, PROTOCOL_TLSv1
+
+    ssl_context = SSLContext(PROTOCOL_TLSv1)
+    ssl_context.load_cert_chain(
+        certfile='/path/to/client.crt_signed',
+        keyfile='/path/to/client.key')
+

Subject: [PATCH 4041/4528] Handle case where there is both TTL and TIMESTAMP

The existing code causes an error like so:
```
cassandra.protocol.SyntaxException: <Error from server: code=2000 [Syntax error in CQL query] message="line 1:101 missing EOF at 'TIMESTAMP' (...({row}) USING TTL {ttl} [USING] TIMESTAMP {timestamp})">
```

by checking for the ttl in the timestamp code we can change the generated query from `USING TTL {ttl} USING TIMESTAMP {timestamp}` => `USING TTL {ttl} AND TIMESTAMP {timestamp}`, which is correct.

Subject: [PATCH 4044/4528] [PYTHON-622] Performance Improvement for
 NetworkTopologyStrategy make_token_replica_map

This updates the `make_token_replica_map` function multiple times
faster. The previous implementation used a combination of islice and cycle.

cycle will build an internal list, and save every element it produces.
`islice` will iterate over everything in it's sequence up to `start`.
I've replaced this with a simple index model which uses the existing list.

Timings on my (admittingly slow) machine for these tests show
differences in speed of:

pre_change:

test_nts_token_performance_large_cluster:
4.509002365055494

test_nts_token_performance_large_with_small_backup
5.222048101015389

post_change:

test_nts_token_performance_large_cluster:
0.2818319270154461

test_nts_token_performance_large_with_small_backup
0.6304094420047477

I've done some more performance testing on a load-testing cluster with
200 nodes and 256 vnodes, and the performance improvement is roughly
30x.

GregBestland added some very useful performance tests for this in [PYTHON-622], however the way
that the tokens were generated and distributed in the ring meant the
tests were quite slow due to the fact that each nodes vnodes tokens were
adjacent in the ring causing many iterations to find the next replica on
a different physical node.

+Documentor
+==========
+We now also use another tool called Documentor with Sphinx source to build docs.
+This gives us versioned docs with nice integrated search. This is a private tool
+of DataStax.
+
+Dependencies
+------------
+Sphinx
+~~~~~~
+Installed as described above
+
+Documentor
+~~~~~~~~~~
+Clone and setup Documentor as specified in `the project <https://github.com/riptano/documentor#installation-and-quick-start>`_.
+This tool assumes Ruby, bundler, and npm are present.
+
+Building
+--------
+The setup script expects documentor to be in the system path. You can either add it permanently or run with something
+like this::
+
+    PATH=$PATH:<documentor repo>/bin python setup.py doc
+
+The docs will not display properly just browsing the filesystem in a browser. To view the docs as they would be in most
+web servers, use the SimpleHTTPServer module::
+
+    cd docs/_build/
+    python -m SimpleHTTPServer
+
+Then, browse to `localhost:8000 <http://localhost:8000>`_.

+DSE Geometry Types
+==================
+This section shows how to query and work with the geometric types provided by DSE.
+
+These types are enabled implicitly by creating the Session from :class:`cassandra.cluster.Cluster`.
+This module implicitly registers these types for use in the driver. This extension provides
+some simple representative types in :mod:`cassandra.util` for inserting and retrieving data::
+
+    from cassandra.cluster import Cluster
+    from cassandra.util import Point, LineString, Polygon
+    session = Cluster().connect()
+
+    session.execute("INSERT INTO ks.geo (k, point, line, poly) VALUES (%s, %s, %s, %s)",
+                    0, Point(1, 2), LineString(((1, 2), (3, 4))), Polygon(((1, 2), (3, 4), (5, 6))))
+
+Queries returning geometric types return the :mod:`dse.util` types. Note that these can easily be used to construct
+types from third-party libraries using the common attributes::
+
+    from shapely.geometry import LineString
+    shapely_linestrings = [LineString(res.line.coords) for res in session.execute("SELECT line FROM ks.geo")]
+
+For prepared statements, shapely geometry types can be used interchangeably with the built-in types because their
+defining attributes are the same::
+
+    from shapely.geometry import Point
+    prepared = session.prepare("UPDATE ks.geo SET point = ? WHERE k = ?")
+    session.execute(prepared, (0, Point(1.2, 3.4)))
+
+In order to use shapely types in a CQL-interpolated (non-prepared) query, one must update the encoder with those types, specifying
+the same string encoder as set for the internal types::
+
+    from cassandra import util
+    from shapely.geometry import Point, LineString, Polygon
+
+    encoder_func = session.encoder.mapping[util.Point]
+    for t in (Point, LineString, Polygon):
+        session.encoder.mapping[t] = encoder_func
+
+    session.execute("UPDATE ks.geo SET point = %s where k = %s", (0, Point(1.2, 3.4)))

+
+See :doc:`getting_started` and :doc:`execution_profiles`
+for more detail on working with profiles.
+
+Getting Started
+~~~~~~~~~~~~~~~
+
+First, we need to create a graph in the system. To access the system API, we 
+use the system execution profile ::
+
+    from cassandra.cluster import Cluster, EXEC_PROFILE_GRAPH_SYSTEM_DEFAULT
+
+    cluster = Cluster()
+    session = cluster.connect()
+
+    graph_name = 'movies'
+    session.execute_graph("system.graph(name).ifNotExists().create()", {'name': graph_name},
+                          execution_profile=EXEC_PROFILE_GRAPH_SYSTEM_DEFAULT)
+
+
+To execute requests on our newly created graph, we need to setup an execution
+profile. Additionally, we also need to set the schema_mode to `development` 
+for the schema creation::
+
+
+    from cassandra.cluster import Cluster, GraphExecutionProfile, EXEC_PROFILE_GRAPH_DEFAULT
+    from cassandra.datastax.graph import GraphOptions
+
+    graph_name = 'movies'
+    ep = GraphExecutionProfile(graph_options=GraphOptions(graph_name=graph_name))
+
+    cluster = Cluster(execution_profiles={EXEC_PROFILE_GRAPH_DEFAULT: ep})
+    session = cluster.connect()
+    
+    session.execute_graph("schema.config().option('graph.schema_mode').set('development')")
+
+
+We are ready to configure our graph schema. We will create a simple one for movies::

+    # An edge represents a relationship between two vertices
+    edges = """

+    schema.edgeLabel("actor").connection("movie","person").create();
+    """
+

+==========   ================
+
+Graph Row Factory
+~~~~~~~~~~~~~~~~~
+
+By default (with :class:`.GraphExecutionProfile.row_factory` set to :func:`.datastax.graph.graph_object_row_factory`), known graph result
+types are unpacked and returned as specialized types (:class:`.Vertex`, :class:`.Edge`). If the result is not one of these
+types, a :class:`.datastax.graph.Result` is returned, containing the graph result parsed from JSON and removed from its outer dict.
+The class has some accessor convenience methods for accessing top-level properties by name (`type`, `properties` above),
+or lists by index::
+
+    # dicts with `__getattr__` or `__getitem__`
+    result = session.execute_graph("[[key_str: 'value', key_int: 3]]", execution_profile=EXEC_PROFILE_GRAPH_SYSTEM_DEFAULT)[0]  # Using system exec just because there is no graph defined
+    result  # cassandra.datastax.graph.Result({u'key_str': u'value', u'key_int': 3})
+    result.value  # {u'key_int': 3, u'key_str': u'value'} (dict)
+    result.key_str  # u'value'
+    result.key_int  # 3
+    result['key_str']  # u'value'
+    result['key_int']  # 3
+
+    # lists with `__getitem__`
+    result = session.execute_graph('[[0, 1, 2]]', execution_profile=EXEC_PROFILE_GRAPH_SYSTEM_DEFAULT)[0]
+    result  # cassandra.datastax.graph.Result([0, 1, 2])
+    result.value  # [0, 1, 2] (list)
+    result[1]  # 1 (list[1])
+
+You can use a different row factory by setting :attr:`.Session.default_graph_row_factory` or passing it to
+:meth:`.Session.execute_graph`. For example, :func:`.datastax.graph.single_object_row_factory` returns the JSON result string`,
+unparsed. :func:`.datastax.graph.graph_result_row_factory` returns parsed, but unmodified results (such that all metadata is retained,
+unlike :func:`.datastax.graph.graph_object_row_factory`, which sheds some as attributes and properties are unpacked). These results
+also provide convenience methods for converting to known types (:meth:`~.Result.as_vertex`, :meth:`~.Result.as_edge`, :meth:`~.Result.as_path`).
+
+Vertex and Edge properties are never unpacked since their types are unknown. If you know your graph schema and want to
+deserialize properties, use the :class:`.datastax.graph.GraphSON1Deserializer`. It provides convenient methods to deserialize by types (e.g.
+deserialize_date, deserialize_uuid, deserialize_polygon etc.) Example::
+
+    # ...
+    from cassandra.datastax.graph import GraphSON1Deserializer
+
+    row = session.execute_graph("g.V().toList()")[0]
+    value = row.properties['my_property_key'][0].value  # accessing the VertexProperty value
+    value = GraphSON1Deserializer.deserialize_timestamp(value)
+
+    print value  # 2017-06-26 08:27:05
+    print type(value)  # <type 'datetime.datetime'>
+
+
+Named Parameters
+~~~~~~~~~~~~~~~~
+
+Named parameters are passed in a dict to :meth:`.cluster.Session.execute_graph`::
+
+    result_set = session.execute_graph('[a, b]', {'a': 1, 'b': 2}, execution_profile=EXEC_PROFILE_GRAPH_SYSTEM_DEFAULT)
+    [r.value for r in result_set]  # [1, 2]
+
+All python types listed in `Graph Types`_ can be passed as named parameters and will be serialized
+automatically to their graph representation:
+
+Example::
+
+    s.execute_graph("""
+      g.addV('person').
+      property('name', text_value).
+      property('age', integer_value).
+      property('birthday', timestamp_value).
+      property('house_yard', polygon_value).toList()
+    """, {
+      'text_value': 'Mike Smith',
+      'integer_value': 34,
+      'timestamp_value': datetime.datetime(1967, 12, 30),
+      'polygon_value': Polygon(((30, 10), (40, 40), (20, 40), (10, 20), (30, 10)))
+    })
+
+
+As with all Execution Profile parameters, graph options can be set in the cluster default (as shown in the first example)
+or specified per execution::
+
+    ep = session.execution_profile_clone_update(EXEC_PROFILE_GRAPH_DEFAULT,
+                                                graph_options=GraphOptions(graph_name='something-else'))
+    session.execute_graph(statement, execution_profile=ep)
+
+Using GraphSON2 Protocol
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+The default graph protocol used is GraphSON1. However GraphSON1 may
+cause problems of type conversion happening during the serialization
+of the query to the DSE Graph server, or the deserialization of the
+responses back from a string Gremlin query. GraphSON2 offers better
+support for the complex data types handled by DSE Graph.
+
+DSE >=5.0.4 now offers the possibility to use the GraphSON2 protocol
+for graph queries. Enabling GraphSON2 can be done by `changing the
+graph protocol of the execution profile` and `setting the graphson2 row factory`::
+
+    from cassandra.cluster import Cluster, GraphExecutionProfile, EXEC_PROFILE_GRAPH_DEFAULT
+    from cassandra.datastax.graph import GraphOptions, GraphProtocol, graph_graphson2_row_factory
+
+    # Create a GraphSON2 execution profile
+    ep = GraphExecutionProfile(graph_options=GraphOptions(graph_name='types',
+                                                          graph_protocol=GraphProtocol.GRAPHSON_2_0),
+                               row_factory=graph_graphson2_row_factory)
+
+    cluster = Cluster(execution_profiles={EXEC_PROFILE_GRAPH_DEFAULT: ep})
+    s = cluster.connect()
+    s.execute_graph(...)
+
+Using GraphSON2, all properties will be automatically deserialized to
+its Python representation. Note that it may bring significant
+behavioral change at runtime.
+
+It is generally recommended to switch to GraphSON2 as it brings more
+consistent support for complex data types in the Graph driver and will
+be activated by default in the next major version (Python dse-driver
+driver 3.0).

+DSE Authentication
+------------------
+When authenticating against DSE, the Cassandra driver provides two auth providers that work both with legacy kerberos and Cassandra authenticators,
+as well as the new DSE Unified Authentication. This allows client to configure this auth provider independently,
+and in advance of any server upgrade. These auth providers are configured in the same way as any previous implementation::
+
+    from cassandra.auth import DSEGSSAPIAuthProvider
+    auth_provider = DSEGSSAPIAuthProvider(service='dse', qops=["auth"])
+    cluster = Cluster(auth_provider=auth_provider)
+    session = cluster.connect()
+
+Implementations are :attr:`.DSEPlainTextAuthProvider`, :class:`.DSEGSSAPIAuthProvider` and :class:`.SaslAuthProvider`.
+
+DSE Unified Authentication
+^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+With DSE (>=5.1), unified Authentication allows you to:
+
+* Proxy Login: Authenticate using a fixed set of authentication credentials but allow authorization of resources based another user id.
+* Proxy Execute: Authenticate using a fixed set of authentication credentials but execute requests based on another user id.
+
+Proxy Login
++++++++++++
+
+Proxy login allows you to authenticate with a user but act as another one. You need to ensure the authenticated user has the permission to use the authorization of resources of the other user. ie. this example will allow the `server` user to authenticate as usual but use the authorization of `user1`:
+
+.. code-block:: text
+
+    GRANT PROXY.LOGIN on role user1 to server
+
+then you can do the proxy authentication....
+
+.. code-block:: python
+
+    from cassandra.cluster import Cluster
+    from cassandra.auth import SaslAuthProvider
+
+    sasl_kwargs = {
+      "service": 'dse',
+      "mechanism":"PLAIN",
+      "username": 'server',
+      'password': 'server',
+      'authorization_id': 'user1'
+    }
+
+    auth_provider = SaslAuthProvider(**sasl_kwargs)
+    c = Cluster(auth_provider=auth_provider)
+    s = c.connect()
+    s.execute(...)  # all requests will be executed as 'user1'
+
+If you are using kerberos, you can use directly :class:`.DSEGSSAPIAuthProvider` and pass the authorization_id, like this:
+
+.. code-block:: python
+
+    from cassandra.cluster import Cluster
+    from cassandra.auth import DSEGSSAPIAuthProvider
+
+    # Ensure the kerberos ticket of the server user is set with the kinit utility.
+    auth_provider = DSEGSSAPIAuthProvider(service='dse', qops=["auth"], principal="server@DATASTAX.COM",
+                                          authorization_id='user1@DATASTAX.COM')
+    c = Cluster(auth_provider=auth_provider)
+    s = c.connect()
+    s.execute(...)  # all requests will be executed as 'user1'
+
+
+Proxy Execute
++++++++++++++
+
+Proxy execute allows you to execute requests as another user than the authenticated one. You need to ensure the authenticated user has the permission to use the authorization of resources of the specified user. ie. this example will allow the `server` user to execute requests as `user1`:
+
+.. code-block:: text
+
+    GRANT PROXY.EXECUTE on role user1 to server
+
+then you can do a proxy execute...
+
+.. code-block:: python
+
+    from cassandra.cluster import Cluster
+    from cassandra.auth import DSEPlainTextAuthProvider,
+
+    auth_provider = DSEPlainTextAuthProvider('server', 'server')
+
+    c = Cluster(auth_provider=auth_provider)
+    s = c.connect()
+    s.execute('select * from k.t;', execute_as='user1')  # the request will be executed as 'user1'
+
+Please see the `official documentation <https://docs.datastax.com/en/latest-dse/datastax_enterprise/unifiedAuth/unifiedAuthTOC.html>`_ for more details on the feature and configuration process.

+DataStax Graph Fluent API
+=========================
+
+The fluent API adds graph features to the core driver::
+
+* A TinkerPop GraphTraversalSource builder to execute traversals on a DSE cluster
+* The ability to execution traversal queries explicitly using execute_graph
+* GraphSON serializers for all DSE Graph types.
+* DSE Search predicates
+
+The Graph fluent API depends on Apache TinkerPop and is not installed by default. Make sure
+you have the Graph requirements are properly :ref:`installed <installation-datastax-graph>`.
+
+You might be interested in reading the :doc:`DSE Graph Getting Started documentation <graph>` to
+understand the basics of creating a graph and its schema.
+
+Graph Traversal Queries
+~~~~~~~~~~~~~~~~~~~~~~~
+
+The driver provides :meth:`.Session.execute_graph`, which allows users to execute traversal
+query strings. Here is a simple example::
+
+    session.execute_graph("g.addV('genre').property('genreId', 1).property('name', 'Action').next();")
+
+Since graph queries can be very complex, working with strings is not very convenient and is
+hard to maintain. This fluent API allows you to build Gremlin traversals and write your graph
+queries directly in Python. These native traversal queries can be executed explicitly, with
+a `Session` object, or implicitly::
+
+    g = DseGraph.traversal_source(session=dse_session)
+    g.addV('genre').property('genreId', 1).property('name', 'Action').next()
+
+    # implicit execution caused by iterating over results
+    for v in g.V().has('genre', 'name', 'Drama').in('belongsTo').valueMap():
+        print(v)
+
+These :ref:`Python types <graph-types>` are also supported transparently::
+
+    g.addV('person').property('name', 'Mike').property('birthday', datetime(1984, 3, 11)). \
+        property('house_yard', Polygon(((30, 10), (40, 40), (20, 40), (10, 20), (30, 10)))
+
+More readings about Gremlin:
+
+* `DataStax Drivers Fluent API <https://www.datastax.com/dev/blog/datastax-drivers-fluent-apis-for-dse-graph-are-out>`_
+* `gremlin-python documentation <http://tinkerpop.apache.org/docs/current/reference/#gremlin-python>`_
+
+Configuring a Traversal Execution Profile
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The fluent api takes advantage of *configuration profiles* to allow
+different execution configurations for the various query handlers. Graph traversal
+execution requires a custom execution profile to enable Gremlin-bytecode as
+query language. Here is how to accomplish this configuration:
+
+.. code-block:: python
+
+    from cassandra.cluster import Cluster, EXEC_PROFILE_GRAPH_DEFAULT
+    from cassandra.datastax.graph.fluent import DseGraph
+
+    ep = DseGraph.create_execution_profile('graph_name')
+    cluster = Cluster(execution_profiles={EXEC_PROFILE_GRAPH_DEFAULT: ep})
+    session = cluster.connect()
+
+    g = DseGraph.traversal_source(session)  # Build the GraphTraversalSource
+    print g.V().toList()  # Traverse the Graph
+
+Note that the execution profile created with :meth:`DseGraph.create_execution_profile <.datastax.graph.fluent.DseGraph.create_execution_profile>` cannot
+be used for any groovy string queries.
+
+If you want to change execution property defaults, please see the :doc:`Execution Profile documentation <execution_profiles>`
+for a more generalized discussion of the API. Graph traversal queries use the same execution profile defined for DSE graph. If you
+need to change the default properties, please refer to the :doc:`DSE Graph query documentation page <graph>`
+
+
+Explicit Graph Traversal Execution with a DSE Session
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Traversal queries can be executed explicitly using `session.execute_graph` or `session.execute_graph_async`. These functions
+return results as DSE graph types. If you are familiar with DSE queries or need async execution, you might prefer that way.
+Below is an example of explicit execution. For this example, assume the schema has been generated as above:
+
+.. code-block:: python
+
+    from cassandra.datastax.graph.fluent import DseGraph
+    from pprint import pprint
+
+    # create a tinkerpop graphson2 ExecutionProfile
+    ep = DseGraph.create_execution_profile('graph_name')
+    cluster = Cluster(execution_profiles={EXEC_PROFILE_GRAPH_DEFAULT: ep})
+    session = cluster.connect()
+
+    g = DseGraph.traversal_source(session=session)
+    addV_query = DseGraph.query_from_traversal(
+        g.addV('genre').property('genreId', 1).property('name', 'Action')
+    )
+    v_query = DseGraph.query_from_traversal(g.V())
+
+    for result in session.execute_graph(addV_query):
+        pprint(result.value)
+    for result in session.execute_graph(v_query):
+        pprint(result.value)
+
+Implicit Graph Traversal Execution with TinkerPop
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Using the :class:`DseGraph <.datastax.graph.fluent.DseGraph>` class, you can build a GraphTraversalSource
+that will execute queries on a DSE session without explicitly passing anything to
+that session. We call this *implicit execution* because the `Session` is not
+explicitly involved. Everything is managed internally by TinkerPop while
+traversing the graph and the results are TinkerPop types as well.
+
+For example:
+
+.. code-block:: python
+
+    # Build the GraphTraversalSource
+    g = DseGraph.traversal_source(session)
+    # implicitly execute the query by traversing the TraversalSource
+    g.addV('genre').property('genreId', 1).property('name', 'Action').next()
+    # view the results of the execution
+    pprint(g.V().toList())
+
+Specify the Execution Profile explicitly
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If you don't want to change the default graph execution profile (`EXEC_PROFILE_GRAPH_DEFAULT`), you can register a new
+one as usual and use it explicitly. Here is an example:
+
+
+.. code-block:: python
+
+    from cassandra.cluster import Cluster
+    from cassandra.datastax.graph.fluent import DseGraph
+
+    cluster = Cluster()
+    ep = DseGraph.create_execution_profile('graph_name')
+    cluster.add_execution_profile('graph_traversal', ep)
+    session = cluster.connect()
+
+    g = DseGraph.traversal_source()
+    query = DseGraph.query_from_traversal(g.V())
+    session.execute_graph(query, execution_profile='graph_traversal')
+
+You can also create multiple GraphTraversalSources and use them with
+the same execution profile (for different graphs):
+
+.. code-block:: python
+
+    g_movies = DseGraph.traversal_source(session, graph_name='movies', ep)
+    g_series = DseGraph.traversal_source(session, graph_name='series', ep)
+
+    print g_movies.V().toList()  # Traverse the movies Graph
+    print g_series.V().toList()  # Traverse the series Graph
+
+Batch Queries
+~~~~~~~~~~~~~
+
+DSE Graph supports batch queries using a :class:`TraversalBatch <.datastax.graph.fluent.query.TraversalBatch>` object
+instantiated with :meth:`DseGraph.batch <.datastax.graph.fluent.DseGraph.batch>`. A :class:`TraversalBatch <.datastax.graph.fluent.query.TraversalBatch>` allows
+you to execute multiple graph traversals in a single atomic transaction. A 
+traversal batch is executed with :meth:`.Session.execute_graph` or using 
+:meth:`TraversalBatch.execute <.datastax.graph.fluent.query.TraversalBatch.execute>` if bounded to a DSE session. 
+
+Either way you choose to execute the traversal batch, you need to configure 
+the execution profile accordingly. Here is a example::
+
+    from cassandra.cluster import Cluster
+    from cassandra.datastax.graph.fluent import DseGraph
+
+    ep = DseGraph.create_execution_profile('graph_name')
+    cluster = Cluster(execution_profiles={'graphson2': ep})
+    session = cluster.connect()
+
+    g = DseGraph.traversal_source()
+
+To execute the batch using :meth:`.Session.execute_graph`, you need to convert
+the batch to a GraphStatement::
+
+    batch = DseGraph.batch()
+
+    batch.add(
+        g.addV('genre').property('genreId', 1).property('name', 'Action'))
+    batch.add(
+        g.addV('genre').property('genreId', 2).property('name', 'Drama'))  # Don't use `.next()` with a batch
+
+    graph_statement = batch.as_graph_statement()
+    graph_statement.is_idempotent = True  # configure any Statement parameters if needed...
+    session.execute_graph(graph_statement, execution_profile='graphson2')
+
+To execute the batch using :meth:`TraversalBatch.execute <.datastax.graph.fluent.query.TraversalBatch.execute>`, you need to bound the batch to a DSE session::
+
+    batch = DseGraph.batch(session, 'graphson2')  # bound the session and execution profile
+
+    batch.add(
+        g.addV('genre').property('genreId', 1).property('name', 'Action'))
+    batch.add(
+        g.addV('genre').property('genreId', 2).property('name', 'Drama'))  # Don't use `.next()` with a batch
+
+    batch.execute()
+
+DSL (Domain Specific Languages)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+DSL are very useful to write better domain-specific APIs and avoiding
+code duplication. Let's say we have a graph of `People` and we produce
+a lot of statistics based on age. All graph traversal queries of our
+application would look like::
+
+  g.V().hasLabel("people").has("age", P.gt(21))...
+
+
+which is not really verbose and quite annoying to repeat in a code base. Let's create a DSL::
+
+  from gremlin_python.process.graph_traversal import GraphTraversal, GraphTraversalSource
+
+  class MyAppTraversal(GraphTraversal):
+
+    def younger_than(self, age):
+        return self.has("age", P.lt(age))
+
+    def older_than(self, age):
+        return self.has("age", P.gt(age))
+
+
+  class MyAppTraversalSource(GraphTraversalSource):
+
+    def __init__(self, *args, **kwargs):
+        super(MyAppTraversalSource, self).__init__(*args, **kwargs)
+        self.graph_traversal = MyAppTraversal
+
+    def people(self):
+        return self.get_graph_traversal().V().hasLabel("people")
+
+Now, we can use our DSL that is a lot cleaner::
+
+  from dse_graph import DseGraph
+
+  # ...
+  g = DseGraph.traversal_source(session=session, traversal_class=MyAppTraversalsource)
+
+  g.people().younger_than(21)...
+  g.people().older_than(30)...
+
+To see a more complete example of DSL, see the `Python killrvideo DSL app <https://github.com/datastax/graph-examples/tree/master/killrvideo/dsl/python>`_
+
+Search
+~~~~~~
+
+DSE Graph can use search indexes that take advantage of DSE Search functionality for
+efficient traversal queries. Here are the list of additional search predicates:
+
+Text tokenization:
+
+* :meth:`token <.datastax.graph.fluent.predicates.Search.token>`
+* :meth:`token_prefix <.datastax.graph.fluent.predicates.Search.token_prefix>`
+* :meth:`token_regex <.datastax.graph.fluent.predicates.Search.token_regex>`
+* :meth:`token_fuzzy <.datastax.graph.fluent.predicates.Search.token_fuzzy>`
+
+Text match:
+
+* :meth:`prefix <.datastax.graph.fluent.predicates.Search.prefix>`
+* :meth:`regex <.datastax.graph.fluent.predicates.Search.regex>`
+* :meth:`fuzzy <.datastax.graph.fluent.predicates.Search.fuzzy>`
+* :meth:`phrase <.datastax.graph.fluent.predicates.Search.phrase>`
+
+Geo:
+
+* :meth:`inside <.datastax.graph.fluent.predicates.Geo.inside>`
+
+Create search indexes
+---------------------
+
+For text tokenization:
+
+.. code-block:: python
+
+
+    s.execute_graph("schema.vertexLabel('my_vertex_label').index('search').search().by('text_field').asText().add()")
+
+For text match:
+
+.. code-block:: python
+
+
+    s.execute_graph("schema.vertexLabel('my_vertex_label').index('search').search().by('text_field').asString().add()")
+
+
+For geospatial:
+
+You can create a geospatial index on Point and LineString fields.
+
+.. code-block:: python
+
+
+    s.execute_graph("schema.vertexLabel('my_vertex_label').index('search').search().by('point_field').add()")
+
+
+Using search indexes
+--------------------
+
+Token:
+
+.. code-block:: python
+
+    from cassandra.datastax.graph.fluent.predicates import Search
+    # ...
+
+    g = DseGraph.traversal_source()
+    query = DseGraph.query_from_traversal(
+        g.V().has('my_vertex_label','text_field', Search.token_regex('Hello.+World')).values('text_field'))
+    session.execute_graph(query)
+
+Text:
+
+.. code-block:: python
+
+    from cassandra.datastax.graph.fluent.predicates import Search
+    # ...
+
+    g = DseGraph.traversal_source()
+    query = DseGraph.query_from_traversal(
+        g.V().has('my_vertex_label','text_field', Search.prefix('Hello')).values('text_field'))
+    session.execute_graph(query)
+
+Geospatial:
+
+.. code-block:: python
+
+    from cassandra.datastax.graph.fluent.predicates import Geo
+    from cassandra.util import Distance
+    # ...
+
+    g = DseGraph.traversal_source()
+    query = DseGraph.query_from_traversal(
+        g.V().has('my_vertex_label','point_field', Geo.inside(Distance(46, 71, 100)).values('point_field'))
+    session.execute_graph(query)

+Cloud
+-----
+Connecting
+==========
+To connect to a DataStax Apollo cluster:
+
+1. Download the secure connect bundle from your Apollo account.
+2. Connect to your cluster with
+
+.. code-block:: python
+
+    from cassandra.cluster import Cluster
+    from cassandra.auth import PlainTextAuthProvider
+
+    cloud_config = {
+        'secure_connect_bundle': '/path/to/secure-connect-dbname.zip'
+    }
+    auth_provider = PlainTextAuthProvider(username='user', password='pass')
+    cluster = Cluster(cloud=cloud_config, auth_provider=auth_provider)
+    session = cluster.connect()
+
+Apollo Differences
+=================
+In most circumstances, the client code for interacting with an Apollo cluster will be the same as interacting with any other Cassandra cluster. The exceptions being:

 Apollo Differences
-=================
+==================
 In most circumstances, the client code for interacting with an Apollo cluster will be the same as interacting with any other Cassandra cluster. The exceptions being:
 
  * A cloud configuration must be passed to a :class:`~.Cluster` instance via the `cloud` attribute (as demonstrated above).
  * An SSL connection will be established automatically. Manual SSL configuration is not allowed, and using `ssl_context` or `ssl_options` will result in an exception.
  * A :class:`~.Cluster`'s `contact_points` attribute should not be used. The cloud config contains all of the necessary contact information.
  * If a consistency level is not specified for an execution profile or query, then :attr:`.ConsistencyLevel.LOCAL_QUORUM` will be used as the default.
+
+Limitations
+===========
+
+Event loops
+-----------
+
+Twisted and Evenlet aren't supported yet. These event loops are still using the old way to configure
+SSL (ssl_options), which is not compatible with the secure connect bundle provided by Apollo.

 ==================
 In most circumstances, the client code for interacting with an Apollo cluster will be the same as interacting with any other Cassandra cluster. The exceptions being:
 
- * A cloud configuration must be passed to a :class:`~.Cluster` instance via the `cloud` attribute (as demonstrated above).
- * An SSL connection will be established automatically. Manual SSL configuration is not allowed, and using `ssl_context` or `ssl_options` will result in an exception.
- * A :class:`~.Cluster`'s `contact_points` attribute should not be used. The cloud config contains all of the necessary contact information.
- * If a consistency level is not specified for an execution profile or query, then :attr:`.ConsistencyLevel.LOCAL_QUORUM` will be used as the default.

 Twisted and Evenlet aren't supported yet. These event loops are still using the old way to configure
 SSL (ssl_options), which is not compatible with the secure connect bundle provided by Apollo.

 TimeUUID Functions
 ==================
 
-    In addition to querying using regular values, there are two functions you can pass in when querying TimeUUID columns to help make filtering by them easier. Note that these functions don't actually return a value, but instruct the cql interpreter to use the functions in it's query.

 Token Function
 ==============
 
-    Token functon may be used only on special, virtual column pk__token, representing token of partition key (it also works for composite partition keys).
-    Cassandra orders returned items by value of partition key token, so using cqlengine.Token we can easy paginate through all table rows.

 Values Lists
 ============
 
-    There is a special QuerySet's method ``.values_list()`` - when called, QuerySet returns lists of values instead of model instances. It may significantly speedup things with lower memory footprint for large responses.
-    Each tuple contains the value from the respective field passed into the ``values_list()`` call — so the first item is the first field, etc. For example:

Subject: [PATCH 4191/4528] [PYTHON-1161] Support Twisted context.

Refactored Twisted code to use newer Endpoint APIs. This allowed us to remove ClientFactory implementation completely.

Also used IOpenSSLClientConnectionCreator interface instead of implementing a ContextFactory. This allows us to use our own context and pyOpenSSL connection instead of relying on twisted to create it for us.

+Twisted uses an alternative SSL implementation called pyOpenSSL, so if your `Cluster`'s connection class is

 SSL Configuration Examples

+DataStax Classic Graph Queries
+==============================
+
+Getting Started
+~~~~~~~~~~~~~~~
+
+First, we need to create a graph in the system. To access the system API, we 
+use the system execution profile ::
+
+    from cassandra.cluster import Cluster, EXEC_PROFILE_GRAPH_SYSTEM_DEFAULT
+
+    cluster = Cluster()
+    session = cluster.connect()
+
+    graph_name = 'movies'
+    session.execute_graph("system.graph(name).ifNotExists().engine(Classic).create()", {'name': graph_name},
+                          execution_profile=EXEC_PROFILE_GRAPH_SYSTEM_DEFAULT)
+
+
+To execute requests on our newly created graph, we need to setup an execution
+profile. Additionally, we also need to set the schema_mode to `development` 
+for the schema creation::
+
+
+    from cassandra.cluster import Cluster, GraphExecutionProfile, EXEC_PROFILE_GRAPH_DEFAULT
+    from cassandra.graph import GraphOptions
+
+    graph_name = 'movies'
+    ep = GraphExecutionProfile(graph_options=GraphOptions(graph_name=graph_name))
+
+    cluster = Cluster(execution_profiles={EXEC_PROFILE_GRAPH_DEFAULT: ep})
+    session = cluster.connect()
+    
+    session.execute_graph("schema.config().option('graph.schema_mode').set('development')")
+
+
+We are ready to configure our graph schema. We will create a simple one for movies::
+
+    # properties are used to define a vertex
+    properties = """
+    schema.propertyKey("genreId").Text().create();
+    schema.propertyKey("personId").Text().create();
+    schema.propertyKey("movieId").Text().create();
+    schema.propertyKey("name").Text().create();
+    schema.propertyKey("title").Text().create();
+    schema.propertyKey("year").Int().create();
+    schema.propertyKey("country").Text().create();
+    """
+
+    session.execute_graph(properties)  # we can execute multiple statements in a single request
+
+    # A Vertex represents a "thing" in the world.
+    vertices = """
+    schema.vertexLabel("genre").properties("genreId","name").create();
+    schema.vertexLabel("person").properties("personId","name").create();
+    schema.vertexLabel("movie").properties("movieId","title","year","country").create();
+    """
+
+    session.execute_graph(vertices)
+
+    # An edge represents a relationship between two vertices
+    edges = """
+    schema.edgeLabel("belongsTo").single().connection("movie","genre").create();
+    schema.edgeLabel("actor").connection("movie","person").create();
+    """
+
+    session.execute_graph(edges)
+
+    # Indexes to execute graph requests efficiently
+    indexes = """
+    schema.vertexLabel("genre").index("genresById").materialized().by("genreId").add();
+    schema.vertexLabel("genre").index("genresByName").materialized().by("name").add();
+    schema.vertexLabel("person").index("personsById").materialized().by("personId").add();
+    schema.vertexLabel("person").index("personsByName").materialized().by("name").add();
+    schema.vertexLabel("movie").index("moviesById").materialized().by("movieId").add();
+    schema.vertexLabel("movie").index("moviesByTitle").materialized().by("title").add();
+    schema.vertexLabel("movie").index("moviesByYear").secondary().by("year").add();
+    """
+
+Next, we'll add some data::
+
+    session.execute_graph("""
+    g.addV('genre').property('genreId', 1).property('name', 'Action').next();
+    g.addV('genre').property('genreId', 2).property('name', 'Drama').next();
+    g.addV('genre').property('genreId', 3).property('name', 'Comedy').next();
+    g.addV('genre').property('genreId', 4).property('name', 'Horror').next();
+    """)
+
+    session.execute_graph("""
+    g.addV('person').property('personId', 1).property('name', 'Mark Wahlberg').next();
+    g.addV('person').property('personId', 2).property('name', 'Leonardo DiCaprio').next();
+    g.addV('person').property('personId', 3).property('name', 'Iggy Pop').next();
+    """)
+
+    session.execute_graph("""
+    g.addV('movie').property('movieId', 1).property('title', 'The Happening').
+        property('year', 2008).property('country', 'United States').next();
+    g.addV('movie').property('movieId', 2).property('title', 'The Italian Job').
+        property('year', 2003).property('country', 'United States').next();
+
+    g.addV('movie').property('movieId', 3).property('title', 'Revolutionary Road').
+        property('year', 2008).property('country', 'United States').next();
+    g.addV('movie').property('movieId', 4).property('title', 'The Man in the Iron Mask').
+        property('year', 1998).property('country', 'United States').next();
+
+    g.addV('movie').property('movieId', 5).property('title', 'Dead Man').
+        property('year', 1995).property('country', 'United States').next();
+    """)
+
+Now that our genre, actor and movie vertices are added, we'll create the relationships (edges) between them::
+
+    session.execute_graph("""
+    genre_horror = g.V().hasLabel('genre').has('name', 'Horror').next();
+    genre_drama = g.V().hasLabel('genre').has('name', 'Drama').next();
+    genre_action = g.V().hasLabel('genre').has('name', 'Action').next();
+
+    leo  = g.V().hasLabel('person').has('name', 'Leonardo DiCaprio').next();
+    mark = g.V().hasLabel('person').has('name', 'Mark Wahlberg').next();
+    iggy = g.V().hasLabel('person').has('name', 'Iggy Pop').next();
+
+    the_happening = g.V().hasLabel('movie').has('title', 'The Happening').next();
+    the_italian_job = g.V().hasLabel('movie').has('title', 'The Italian Job').next();
+    rev_road = g.V().hasLabel('movie').has('title', 'Revolutionary Road').next();
+    man_mask = g.V().hasLabel('movie').has('title', 'The Man in the Iron Mask').next();
+    dead_man = g.V().hasLabel('movie').has('title', 'Dead Man').next();
+
+    the_happening.addEdge('belongsTo', genre_horror);
+    the_italian_job.addEdge('belongsTo', genre_action);
+    rev_road.addEdge('belongsTo', genre_drama);
+    man_mask.addEdge('belongsTo', genre_drama);
+    man_mask.addEdge('belongsTo', genre_action);
+    dead_man.addEdge('belongsTo', genre_drama);
+
+    the_happening.addEdge('actor', mark);
+    the_italian_job.addEdge('actor', mark);
+    rev_road.addEdge('actor', leo);
+    man_mask.addEdge('actor', leo);
+    dead_man.addEdge('actor', iggy);
+    """)
+
+We are all set. You can now query your graph. Here are some examples::
+
+    # Find all movies of the genre Drama
+    for r in session.execute_graph("""
+      g.V().has('genre', 'name', 'Drama').in('belongsTo').valueMap();"""):
+        print(r)
+    
+    # Find all movies of the same genre than the movie 'Dead Man'
+    for r in session.execute_graph("""
+      g.V().has('movie', 'title', 'Dead Man').out('belongsTo').in('belongsTo').valueMap();"""):
+        print(r)
+
+    # Find all movies of Mark Wahlberg
+    for r in session.execute_graph("""
+      g.V().has('person', 'name', 'Mark Wahlberg').in('actor').valueMap();"""):
+        print(r)
+

+
+Graph Types
+~~~~~~~~~~~
+
+Here are the supported graph types with their python representations:
+
+==========   ================
+DSE Graph    Python
+==========   ================
+boolean      bool
+bigint       long, int (PY3)
+int          int
+smallint     int
+varint       int
+float        float
+double       double
+uuid         uuid.UUID
+Decimal      Decimal
+inet         str
+timestamp    datetime.datetime
+date         datetime.date
+time         datetime.time
+duration     datetime.timedelta
+point        Point
+linestring   LineString
+polygon      Polygon
+blob         bytearray, buffer (PY2), memoryview (PY3), bytes (PY3)
+==========   ================
+
+Graph Row Factory
+~~~~~~~~~~~~~~~~~
+
+By default (with :class:`.GraphExecutionProfile.row_factory` set to :func:`.graph.graph_object_row_factory`), known graph result
+types are unpacked and returned as specialized types (:class:`.Vertex`, :class:`.Edge`). If the result is not one of these
+types, a :class:`.graph.Result` is returned, containing the graph result parsed from JSON and removed from its outer dict.
+The class has some accessor convenience methods for accessing top-level properties by name (`type`, `properties` above),
+or lists by index::
+
+    # dicts with `__getattr__` or `__getitem__`
+    result = session.execute_graph("[[key_str: 'value', key_int: 3]]", execution_profile=EXEC_PROFILE_GRAPH_SYSTEM_DEFAULT)[0]  # Using system exec just because there is no graph defined
+    result  # dse.graph.Result({u'key_str': u'value', u'key_int': 3})
+    result.value  # {u'key_int': 3, u'key_str': u'value'} (dict)
+    result.key_str  # u'value'
+    result.key_int  # 3
+    result['key_str']  # u'value'
+    result['key_int']  # 3
+
+    # lists with `__getitem__`
+    result = session.execute_graph('[[0, 1, 2]]', execution_profile=EXEC_PROFILE_GRAPH_SYSTEM_DEFAULT)[0]
+    result  # dse.graph.Result([0, 1, 2])
+    result.value  # [0, 1, 2] (list)
+    result[1]  # 1 (list[1])
+
+You can use a different row factory by setting :attr:`.Session.default_graph_row_factory` or passing it to
+:meth:`.Session.execute_graph`. For example, :func:`.graph.single_object_row_factory` returns the JSON result string`,
+unparsed. :func:`.graph.graph_result_row_factory` returns parsed, but unmodified results (such that all metadata is retained,
+unlike :func:`.graph.graph_object_row_factory`, which sheds some as attributes and properties are unpacked). These results
+also provide convenience methods for converting to known types (:meth:`~.Result.as_vertex`, :meth:`~.Result.as_edge`, :meth:`~.Result.as_path`).
+
+Vertex and Edge properties are never unpacked since their types are unknown. If you know your graph schema and want to
+deserialize properties, use the :class:`.GraphSON1Deserializer`. It provides convenient methods to deserialize by types (e.g.
+deserialize_date, deserialize_uuid, deserialize_polygon etc.) Example::
+
+    # ...
+    from cassandra.graph import GraphSON1Deserializer
+
+    row = session.execute_graph("g.V().toList()")[0]
+    value = row.properties['my_property_key'][0].value  # accessing the VertexProperty value
+    value = GraphSON1Deserializer.deserialize_timestamp(value)
+
+    print(value)  # 2017-06-26 08:27:05
+    print(type(value))  # <type 'datetime.datetime'>
+
+
+Named Parameters
+~~~~~~~~~~~~~~~~
+
+Named parameters are passed in a dict to :meth:`.cluster.Session.execute_graph`::
+
+    result_set = session.execute_graph('[a, b]', {'a': 1, 'b': 2}, execution_profile=EXEC_PROFILE_GRAPH_SYSTEM_DEFAULT)
+    [r.value for r in result_set]  # [1, 2]
+
+All python types listed in `Graph Types`_ can be passed as named parameters and will be serialized
+automatically to their graph representation:
+
+Example::
+
+    session.execute_graph("""
+      g.addV('person').
+      property('name', text_value).
+      property('age', integer_value).
+      property('birthday', timestamp_value).
+      property('house_yard', polygon_value).toList()
+    """, {
+      'text_value': 'Mike Smith',
+      'integer_value': 34,
+      'timestamp_value': datetime.datetime(1967, 12, 30),
+      'polygon_value': Polygon(((30, 10), (40, 40), (20, 40), (10, 20), (30, 10)))
+    })
+
+
+As with all Execution Profile parameters, graph options can be set in the cluster default (as shown in the first example)
+or specified per execution::
+
+    ep = session.execution_profile_clone_update(EXEC_PROFILE_GRAPH_DEFAULT,
+                                                graph_options=GraphOptions(graph_name='something-else'))
+    session.execute_graph(statement, execution_profile=ep)
+
+Using GraphSON2 Protocol
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+The default graph protocol used is GraphSON1. However GraphSON1 may
+cause problems of type conversion happening during the serialization
+of the query to the DSE Graph server, or the deserialization of the
+responses back from a string Gremlin query. GraphSON2 offers better
+support for the complex data types handled by DSE Graph.
+
+DSE >=5.0.4 now offers the possibility to use the GraphSON2 protocol
+for graph queries. Enabling GraphSON2 can be done by `changing the
+graph protocol of the execution profile` and `setting the graphson2 row factory`::
+
+    from cassandra.cluster import Cluster, GraphExecutionProfile, EXEC_PROFILE_GRAPH_DEFAULT
+    from cassandra.graph import GraphOptions, GraphProtocol, graph_graphson2_row_factory
+
+    # Create a GraphSON2 execution profile
+    ep = GraphExecutionProfile(graph_options=GraphOptions(graph_name='types',
+                                                          graph_protocol=GraphProtocol.GRAPHSON_2_0),
+                               row_factory=graph_graphson2_row_factory)
+
+    cluster = Cluster(execution_profiles={EXEC_PROFILE_GRAPH_DEFAULT: ep})
+    session = cluster.connect()
+    session.execute_graph(...)
+
+Using GraphSON2, all properties will be automatically deserialized to
+its Python representation. Note that it may bring significant
+behavioral change at runtime.
+
+It is generally recommended to switch to GraphSON2 as it brings more
+consistent support for complex data types in the Graph driver and will
+be activated by default in the next major version (Python dse-driver
+driver 3.0).

-==========   ================
-
-Graph Row Factory
-~~~~~~~~~~~~~~~~~
-
-By default (with :class:`.GraphExecutionProfile.row_factory` set to :func:`.datastax.graph.graph_object_row_factory`), known graph result
-types are unpacked and returned as specialized types (:class:`.Vertex`, :class:`.Edge`). If the result is not one of these
-types, a :class:`.datastax.graph.Result` is returned, containing the graph result parsed from JSON and removed from its outer dict.
-The class has some accessor convenience methods for accessing top-level properties by name (`type`, `properties` above),
-or lists by index::
-
-    # dicts with `__getattr__` or `__getitem__`
-    result = session.execute_graph("[[key_str: 'value', key_int: 3]]", execution_profile=EXEC_PROFILE_GRAPH_SYSTEM_DEFAULT)[0]  # Using system exec just because there is no graph defined
-    result  # cassandra.datastax.graph.Result({u'key_str': u'value', u'key_int': 3})
-    result.value  # {u'key_int': 3, u'key_str': u'value'} (dict)
-    result.key_str  # u'value'
-    result.key_int  # 3
-    result['key_str']  # u'value'
-    result['key_int']  # 3
-
-    # lists with `__getitem__`
-    result = session.execute_graph('[[0, 1, 2]]', execution_profile=EXEC_PROFILE_GRAPH_SYSTEM_DEFAULT)[0]
-    result  # cassandra.datastax.graph.Result([0, 1, 2])
-    result.value  # [0, 1, 2] (list)
-    result[1]  # 1 (list[1])
-
-You can use a different row factory by setting :attr:`.cluster.ExecutionProfile.row_factory` or passing it to
-:meth:`cluster.Session.execute_graph`. For example, :func:`.datastax.graph.single_object_row_factory` returns the JSON result string,
-unparsed. :func:`.datastax.graph.graph_result_row_factory` returns parsed, but unmodified results (such that all metadata is retained,
-unlike :func:`.datastax.graph.graph_object_row_factory`, which sheds some as attributes and properties are unpacked). These results
-also provide convenience methods for converting to known types (:meth:`.datastax.graph.Result.as_vertex`, :meth:`.datastax.graph.Result.as_edge`,
- :meth:`.datastax.graph.Result.as_path`).
-
-Vertex and Edge properties are never unpacked since their types are unknown. If you know your graph schema and want to
-deserialize properties, use the :class:`.datastax.graph.GraphSON1Deserializer`. It provides convenient methods to deserialize by types (e.g.
-deserialize_date, deserialize_uuid, deserialize_polygon etc.) Example::
-
-    # ...
-    from cassandra.datastax.graph import GraphSON1Deserializer
-
-    row = session.execute_graph("g.V().toList()")[0]
-    value = row.properties['my_property_key'][0].value  # accessing the VertexProperty value
-    value = GraphSON1Deserializer.deserialize_timestamp(value)
-
-    print value  # 2017-06-26 08:27:05
-    print type(value)  # <type 'datetime.datetime'>

-Using GraphSON2 Protocol
-~~~~~~~~~~~~~~~~~~~~~~~~
+CQL collections, Tuple and UDT
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
-The default graph protocol used is GraphSON1. However GraphSON1 may

-of the query to the DSE Graph server, or the deserialization of the
-responses back from a string Gremlin query. GraphSON2 offers better
-support for the complex data types handled by DSE Graph.

+list, map, set, tuple and udt. Here is an example using all these types::

+    )
+
+    # error: [Invalid query] message="Value component 1 is of type int, not bigint"
+
+This is because the server requires the client to include a GraphSON schema definition
+with every UDT or tuple query. In the general case, the driver can't determine what Graph type
+is meant by, e.g., an int value, and so it can't serialize the value with the correct type in the schema.
+The driver provides some numerical type-wrapper factories that you can use to specify types:
+
+* :func:`~.to_int`
+* :func:`~.to_bigint`
+* :func:`~.to_smallint`
+* :func:`~.to_float`
+* :func:`~.to_double`
+
+Here's the working example of the case above::
+
+    from cassandra.graph import to_bigint
+
+     session.execute_graph("""
+        g.addV('test_tuple').property('id', 0).property('t', t)
+          """, 
+          {'t': ('Test', to_bigint(99))}
+    )
 
-It is generally recommended to switch to GraphSON2 as it brings more
-consistent support for complex data types in the Graph driver and will
-be activated by default in the next major version (Python dse-driver
-driver 3.0).
+Continuous Paging
+~~~~~~~~~~~~~~~~~
+
+This is another nice feature that comes with the core engine: continuous paging with
+graph queries. If all nodes of the cluster are >= DSE 6.8.0, it is automatically
+enabled under the hood to get the best performance. If you want to explicitly
+enable/disable it, you can do it through the execution profile::
+
+    # Disable it
+    ep = GraphExecutionProfile(..., continuous_paging_options=None))
+    cluster = Cluster(execution_profiles={EXEC_PROFILE_GRAPH_DEFAULT: ep})
+
+    # Enable with a custom max_pages option
+    ep = GraphExecutionProfile(...,
+        continuous_paging_options=ContinuousPagingOptions(max_pages=10)))
+    cluster = Cluster(execution_profiles={EXEC_PROFILE_GRAPH_DEFAULT: ep})

+Upgrading from dse-driver
+-------------------------
+
+Since 3.21.0, cassandra-driver fully supports DataStax products. dse-driver and
+dse-graph users should now migrate to cassandra-driver to benefit from latest bug fixes
+and new features. The upgrade to this new unified driver version is straightforward
+with no major API changes.
+
+Installation
+^^^^^^^^^^^^
+
+Only the `cassandra-driver` package should be installed. `dse-driver` and `dse-graph`
+are not required anymore::
+
+    pip install cassandra-driver
+
+If you need the Graph *Fluent* API (features provided by dse-graph)::
+
+    pip install cassandra-driver[graph]
+
+See :doc:`installation` for more details.
+
+Import from the cassandra module
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+There is no `dse` module, so you should import from the `cassandra` module. You
+need to change only the first module of your import statements, not the submodules.
+
+.. code-block:: python
+
+    from dse.cluster import Cluster, EXEC_PROFILE_GRAPH_DEFAULT
+    from dse.auth import PlainTextAuthProvider
+    from dse.policies import WhiteListRoundRobinPolicy
+
+    # becomes
+
+    from cassandra.cluster import Cluster, EXEC_PROFILE_GRAPH_DEFAULT
+    from cassandra.auth import PlainTextAuthProvider
+    from cassandra.policies import WhiteListRoundRobinPolicy
+
+dse-graph
+^^^^^^^^^
+
+dse-graph features are now built-in in cassandra-driver. The only change you need
+to do is your import statements:
+
+.. code-block:: python
+
+    from dse_graph import ..
+    from dse_graph.query import ..
+
+    # becomes
+
+    from cassandra.datastax.graph.fluent import ..
+    from cassandra.datastax.graph.fluent.query import ..
+
+See :mod:`~.datastax.graph.fluent`.
+
+Session.execute and Session.execute_async API
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Although it is not common to use this API with positional arguments, it is
+important to be aware that the `host` and `execute_as` parameters have had
+their positional order swapped. This is only because `execute_as` was added
+in dse-driver before `host`.
+
+See :meth:`.Session.execute`.
+
+Deprecations
+^^^^^^^^^^^^
+
+These changes are optional, but recommended:
+
+* Importing from `cassandra.graph` is deprecated. Consider importing from `cassandra.datastax.graph`.
+* Use :class:`~.policies.DefaultLoadBalancingPolicy` instead of DSELoadBalancingPolicy.

+If you create your SSLContext using `ssl.create_default_context <https://docs.python.org/3/library/ssl.html#ssl.create_default_context>`_,

+Speculative Execution
+^^^^^^^^^^^^^^^^^^^^^
+
+Speculative execution is a way to minimize latency by preemptively executing several
+instances of the same query against different nodes. For more details about this
+technique, see `Speculative Execution with DataStax Drivers <https://docs.datastax.com/en/devapp/doc/devapp/driversSpeculativeRetry.html>`_.
+
+To enable speculative execution:
+
+* Configure a :class:`~.policies.SpeculativeExecutionPolicy` with the ExecutionProfile
+* Mark your query as idempotent, which mean it can be applied multiple
+  times without changing the result of the initial application.
+  See `Query Idempotence <https://docs.datastax.com/en/devapp/doc/devapp/driversQueryIdempotence.html>`_ for more details.
+
+
+Example:
+
+.. code-block:: python
+
+    from cassandra.cluster import Cluster, ExecutionProfile, EXEC_PROFILE_DEFAULT
+    from cassandra.policies import ConstantSpeculativeExecutionPolicy
+    from cassandra.query import SimpleStatement
+
+    # Configure the speculative execution policy

+        speculative_execution_policy=ConstantSpeculativeExecutionPolicy(delay=.5, max_attempts=10)
+    )
+    cluster = Cluster(..., execution_profiles={EXEC_PROFILE_DEFAULT: ep})

+    # Mark the query idempotent
+    query = SimpleStatement(
+        "UPDATE my_table SET list_col = [1] WHERE pk = 1",
+        is_idempotent=True
+    )
+
+    # Execute. A new query will be sent to the server every 0.5 second
+    # until we receive a response, for a max number attempts of 10.

+As mentioned in our `Drivers Best Practices Guide <https://docs.datastax.com/en/devapp/doc/devapp/driversBestPractices.html#driversBestPractices__usePreparedStatements>`_,

+Prepared Statements
+-------------------
+Prepared statements are queries that are parsed by Cassandra and then saved
+for later use.  When the driver uses a prepared statement, it only needs to
+send the values of parameters to bind.  This lowers network traffic
+and CPU utilization within Cassandra because Cassandra does not have to
+re-parse the query each time.
+
+To prepare a query, use :meth:`.Session.prepare()`:
+
+.. code-block:: python
+
+    user_lookup_stmt = session.prepare("SELECT * FROM users WHERE user_id=?")
+
+    users = []
+    for user_id in user_ids_to_query:
+        user = session.execute(user_lookup_stmt, [user_id])
+        users.append(user)
+
+:meth:`~.Session.prepare()` returns a :class:`~.PreparedStatement` instance
+which can be used in place of :class:`~.SimpleStatement` instances or literal
+string queries.  It is automatically prepared against all nodes, and the driver
+handles re-preparing against new nodes and restarted nodes when necessary.
+
+Note that the placeholders for prepared statements are ``?`` characters.  This
+is different than for simple, non-prepared statements (although future versions
+of the driver may use the same placeholders for both).
 
 Passing Parameters to CQL Queries
 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-When executing non-prepared statements, the driver supports two forms of
-parameter place-holders: positional and named.
+Althought it is not recommended, you can also pass parameters to non-prepared

-.. code-block:: python
-
-    user_lookup_stmt = session.prepare("SELECT * FROM users WHERE user_id=?")
-
-    users = []
-    for user_id in user_ids_to_query:
-        user = session.execute(user_lookup_stmt, [user_id])
-        users.append(user)
-
-:meth:`~.Session.prepare()` returns a :class:`~.PreparedStatement` instance
-which can be used in place of :class:`~.SimpleStatement` instances or literal
-string queries.  It is automatically prepared against all nodes, and the driver
-handles re-preparing against new nodes and restarted nodes when necessary.
-
-Note that the placeholders for prepared statements are ``?`` characters.  This
-is different than for simple, non-prepared statements (although future versions
-of the driver may use the same placeholders for both).
-
 Setting a Consistency Level with Prepared Statements
 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
 To specify a consistency level for prepared statements, you have two options.

+===========================================
+A Python client driver for `Apache Cassandra <http://cassandra.apache.org>`_.
+This driver works exclusively with the Cassandra Query Language v3 (CQL3)
 and Cassandra's native protocol.  Cassandra 2.1+ is supported, including DSE 4.7+.
 
 The driver supports Python 2.7, 3.4, 3.5, 3.6, 3.7 and 3.8.

 ***Note**: if intending to use optional extensions, install the `dependencies <#optional-non-python-dependencies>`_ first. The driver may need to be reinstalled if dependencies are added after the initial installation.
 
+Verifying your Installation

+---------------------------
+The driver provides an optional fluent graph API that depends on Apache TinkerPop (gremlinpython). It is
+not installed by default. To be able to build Gremlin traversals, you need to install
+the `graph` requirements::
+
+    pip install cassandra-driver[graph]

+
+(*Optional*) Compression Support
+--------------------------------
+Compression can optionally be used for communication between the driver and
+Cassandra.  There are currently two supported compression algorithms:
+snappy (in Cassandra 1.2+) and LZ4 (only in Cassandra 2.0+).  If either is
+available for the driver and Cassandra also supports it, it will

+For lz4 support::

+    pip install lz4

+
+(If using a Debian Linux derivative such as Ubuntu, it may be easier to
+just run ``apt-get install python-snappy``.)

Subject: [PATCH 4260/4528] Changes from test failures.

Move session id creation before insights reporter starts. When the insights reporter retrieves the startup data, it captures the session id. Since this runs in a separate thread, the session id is usually created by the time this capture actually runs. But it's a race, and sessionId can occassionally be captured as None.

Fix tests/integration/cqlengine/model/test_model.py:TestDeprecationWarning.test_deprecation_warnings: Asyncio throws warnings on python 2.7+ that aren't relevant to the test, so ignore them.

Subject: [PATCH 4262/4528] Test 68 (#1066)

6.8 test changes
* Materialized view tests: You now can't create a MV with clustering order by unless you specify ALL of the clustering columns. So tests are updated to do that.
* DuplicateRpcTest: We used to be able to update system.peers, but that's not allowed anymore, so converted it to a simulacron test. Updated another test to use mocks for the same reason.
* Updated virtual keyspace test to not verify exact structure since that will change between versions. Rather, verify a few known values that should exist in all versions to verify we parsed the structure correctly.
* Tombstone settings have moved under guardrails, and delete entire row instead of just cells in tombstone tests due to DB-2426.
* Added a few optional env vars to allow management of an external cluster
* DSE version checks

-DataStax Classic Graph Queries
-==============================
-
-Getting Started
-~~~~~~~~~~~~~~~
-
-First, we need to create a graph in the system. To access the system API, we 
-use the system execution profile ::
-
-    from cassandra.cluster import Cluster, EXEC_PROFILE_GRAPH_SYSTEM_DEFAULT
-
-    cluster = Cluster()
-    session = cluster.connect()
-
-    graph_name = 'movies'
-    session.execute_graph("system.graph(name).ifNotExists().engine(Classic).create()", {'name': graph_name},
-                          execution_profile=EXEC_PROFILE_GRAPH_SYSTEM_DEFAULT)
-
-
-To execute requests on our newly created graph, we need to setup an execution
-profile. Additionally, we also need to set the schema_mode to `development` 
-for the schema creation::
-
-
-    from cassandra.cluster import Cluster, GraphExecutionProfile, EXEC_PROFILE_GRAPH_DEFAULT
-    from cassandra.graph import GraphOptions
-
-    graph_name = 'movies'
-    ep = GraphExecutionProfile(graph_options=GraphOptions(graph_name=graph_name))
-
-    cluster = Cluster(execution_profiles={EXEC_PROFILE_GRAPH_DEFAULT: ep})
-    session = cluster.connect()
-    
-    session.execute_graph("schema.config().option('graph.schema_mode').set('development')")
-
-
-We are ready to configure our graph schema. We will create a simple one for movies::
-
-    # properties are used to define a vertex
-    properties = """
-    schema.propertyKey("genreId").Text().create();
-    schema.propertyKey("personId").Text().create();
-    schema.propertyKey("movieId").Text().create();
-    schema.propertyKey("name").Text().create();
-    schema.propertyKey("title").Text().create();
-    schema.propertyKey("year").Int().create();
-    schema.propertyKey("country").Text().create();
-    """
-
-    session.execute_graph(properties)  # we can execute multiple statements in a single request
-
-    # A Vertex represents a "thing" in the world.
-    vertices = """
-    schema.vertexLabel("genre").properties("genreId","name").create();
-    schema.vertexLabel("person").properties("personId","name").create();
-    schema.vertexLabel("movie").properties("movieId","title","year","country").create();
-    """
-
-    session.execute_graph(vertices)
-
-    # An edge represents a relationship between two vertices
-    edges = """
-    schema.edgeLabel("belongsTo").single().connection("movie","genre").create();
-    schema.edgeLabel("actor").connection("movie","person").create();
-    """
-
-    session.execute_graph(edges)
-
-    # Indexes to execute graph requests efficiently
-    indexes = """
-    schema.vertexLabel("genre").index("genresById").materialized().by("genreId").add();
-    schema.vertexLabel("genre").index("genresByName").materialized().by("name").add();
-    schema.vertexLabel("person").index("personsById").materialized().by("personId").add();
-    schema.vertexLabel("person").index("personsByName").materialized().by("name").add();

-    schema.vertexLabel("movie").index("moviesByTitle").materialized().by("title").add();
-    schema.vertexLabel("movie").index("moviesByYear").secondary().by("year").add();
-    """
-
-Next, we'll add some data::
-
-    session.execute_graph("""
-    g.addV('genre').property('genreId', 1).property('name', 'Action').next();
-    g.addV('genre').property('genreId', 2).property('name', 'Drama').next();
-    g.addV('genre').property('genreId', 3).property('name', 'Comedy').next();
-    g.addV('genre').property('genreId', 4).property('name', 'Horror').next();
-    """)
-
-    session.execute_graph("""
-    g.addV('person').property('personId', 1).property('name', 'Mark Wahlberg').next();
-    g.addV('person').property('personId', 2).property('name', 'Leonardo DiCaprio').next();
-    g.addV('person').property('personId', 3).property('name', 'Iggy Pop').next();
-    """)
-
-    session.execute_graph("""
-    g.addV('movie').property('movieId', 1).property('title', 'The Happening').
-        property('year', 2008).property('country', 'United States').next();
-    g.addV('movie').property('movieId', 2).property('title', 'The Italian Job').
-        property('year', 2003).property('country', 'United States').next();
-
-    g.addV('movie').property('movieId', 3).property('title', 'Revolutionary Road').
-        property('year', 2008).property('country', 'United States').next();
-    g.addV('movie').property('movieId', 4).property('title', 'The Man in the Iron Mask').
-        property('year', 1998).property('country', 'United States').next();

-        property('year', 1995).property('country', 'United States').next();
-    """)
-
-Now that our genre, actor and movie vertices are added, we'll create the relationships (edges) between them::
-
-    session.execute_graph("""
-    genre_horror = g.V().hasLabel('genre').has('name', 'Horror').next();
-    genre_drama = g.V().hasLabel('genre').has('name', 'Drama').next();

-    mark = g.V().hasLabel('person').has('name', 'Mark Wahlberg').next();
-    iggy = g.V().hasLabel('person').has('name', 'Iggy Pop').next();
-
-    the_happening = g.V().hasLabel('movie').has('title', 'The Happening').next();
-    the_italian_job = g.V().hasLabel('movie').has('title', 'The Italian Job').next();
-    rev_road = g.V().hasLabel('movie').has('title', 'Revolutionary Road').next();
-    man_mask = g.V().hasLabel('movie').has('title', 'The Man in the Iron Mask').next();
-    dead_man = g.V().hasLabel('movie').has('title', 'Dead Man').next();
-
-    the_happening.addEdge('belongsTo', genre_horror);
-    the_italian_job.addEdge('belongsTo', genre_action);
-    rev_road.addEdge('belongsTo', genre_drama);
-    man_mask.addEdge('belongsTo', genre_drama);

-    rev_road.addEdge('actor', leo);
-    man_mask.addEdge('actor', leo);
-    dead_man.addEdge('actor', iggy);
-    """)
-
-We are all set. You can now query your graph. Here are some examples::
-
-    # Find all movies of the genre Drama
-    for r in session.execute_graph("""
-      g.V().has('genre', 'name', 'Drama').in('belongsTo').valueMap();"""):
-        print(r)
-    
-    # Find all movies of the same genre than the movie 'Dead Man'
-    for r in session.execute_graph("""
-      g.V().has('movie', 'title', 'Dead Man').out('belongsTo').in('belongsTo').valueMap();"""):
-        print(r)

-    for r in session.execute_graph("""

-        print(r)

-
-Graph Types
-~~~~~~~~~~~
-
-Here are the supported graph types with their python representations:
-
-==========   ================
-DSE Graph    Python
-==========   ================
-boolean      bool
-bigint       long, int (PY3)
-int          int
-smallint     int
-varint       int
-float        float
-double       double
-uuid         uuid.UUID
-Decimal      Decimal
-inet         str
-timestamp    datetime.datetime
-date         datetime.date
-time         datetime.time
-duration     datetime.timedelta
-point        Point
-linestring   LineString
-polygon      Polygon
-blob         bytearray, buffer (PY2), memoryview (PY3), bytes (PY3)
-==========   ================
-
-Graph Row Factory
-~~~~~~~~~~~~~~~~~
-
-By default (with :class:`.GraphExecutionProfile.row_factory` set to :func:`.graph.graph_object_row_factory`), known graph result
-types are unpacked and returned as specialized types (:class:`.Vertex`, :class:`.Edge`). If the result is not one of these
-types, a :class:`.graph.Result` is returned, containing the graph result parsed from JSON and removed from its outer dict.
-The class has some accessor convenience methods for accessing top-level properties by name (`type`, `properties` above),
-or lists by index::
-
-    # dicts with `__getattr__` or `__getitem__`
-    result = session.execute_graph("[[key_str: 'value', key_int: 3]]", execution_profile=EXEC_PROFILE_GRAPH_SYSTEM_DEFAULT)[0]  # Using system exec just because there is no graph defined
-    result  # dse.graph.Result({u'key_str': u'value', u'key_int': 3})
-    result.value  # {u'key_int': 3, u'key_str': u'value'} (dict)
-    result.key_str  # u'value'
-    result.key_int  # 3
-    result['key_str']  # u'value'
-    result['key_int']  # 3
-
-    # lists with `__getitem__`
-    result = session.execute_graph('[[0, 1, 2]]', execution_profile=EXEC_PROFILE_GRAPH_SYSTEM_DEFAULT)[0]
-    result  # dse.graph.Result([0, 1, 2])
-    result.value  # [0, 1, 2] (list)
-    result[1]  # 1 (list[1])
-
-You can use a different row factory by setting :attr:`.Session.default_graph_row_factory` or passing it to
-:meth:`.Session.execute_graph`. For example, :func:`.graph.single_object_row_factory` returns the JSON result string`,
-unparsed. :func:`.graph.graph_result_row_factory` returns parsed, but unmodified results (such that all metadata is retained,
-unlike :func:`.graph.graph_object_row_factory`, which sheds some as attributes and properties are unpacked). These results
-also provide convenience methods for converting to known types (:meth:`~.Result.as_vertex`, :meth:`~.Result.as_edge`, :meth:`~.Result.as_path`).
-
-Vertex and Edge properties are never unpacked since their types are unknown. If you know your graph schema and want to
-deserialize properties, use the :class:`.GraphSON1Deserializer`. It provides convenient methods to deserialize by types (e.g.
-deserialize_date, deserialize_uuid, deserialize_polygon etc.) Example::
-
-    # ...
-    from cassandra.graph import GraphSON1Deserializer
-
-    row = session.execute_graph("g.V().toList()")[0]
-    value = row.properties['my_property_key'][0].value  # accessing the VertexProperty value
-    value = GraphSON1Deserializer.deserialize_timestamp(value)
-
-    print(value)  # 2017-06-26 08:27:05
-    print(type(value))  # <type 'datetime.datetime'>
-
-
-Named Parameters
-~~~~~~~~~~~~~~~~
-
-Named parameters are passed in a dict to :meth:`.cluster.Session.execute_graph`::
-
-    result_set = session.execute_graph('[a, b]', {'a': 1, 'b': 2}, execution_profile=EXEC_PROFILE_GRAPH_SYSTEM_DEFAULT)
-    [r.value for r in result_set]  # [1, 2]
-
-All python types listed in `Graph Types`_ can be passed as named parameters and will be serialized
-automatically to their graph representation:
-
-Example::
-
-    session.execute_graph("""
-      g.addV('person').
-      property('name', text_value).
-      property('age', integer_value).
-      property('birthday', timestamp_value).
-      property('house_yard', polygon_value).toList()
-    """, {
-      'text_value': 'Mike Smith',
-      'integer_value': 34,
-      'timestamp_value': datetime.datetime(1967, 12, 30),
-      'polygon_value': Polygon(((30, 10), (40, 40), (20, 40), (10, 20), (30, 10)))
-    })
-
-
-As with all Execution Profile parameters, graph options can be set in the cluster default (as shown in the first example)
-or specified per execution::
-
-    ep = session.execution_profile_clone_update(EXEC_PROFILE_GRAPH_DEFAULT,
-                                                graph_options=GraphOptions(graph_name='something-else'))
-    session.execute_graph(statement, execution_profile=ep)
-
-Using GraphSON2 Protocol
-~~~~~~~~~~~~~~~~~~~~~~~~
-
-The default graph protocol used is GraphSON1. However GraphSON1 may
-cause problems of type conversion happening during the serialization
-of the query to the DSE Graph server, or the deserialization of the
-responses back from a string Gremlin query. GraphSON2 offers better
-support for the complex data types handled by DSE Graph.
-
-DSE >=5.0.4 now offers the possibility to use the GraphSON2 protocol
-for graph queries. Enabling GraphSON2 can be done by `changing the
-graph protocol of the execution profile` and `setting the graphson2 row factory`::
-
-    from cassandra.cluster import Cluster, GraphExecutionProfile, EXEC_PROFILE_GRAPH_DEFAULT
-    from cassandra.graph import GraphOptions, GraphProtocol, graph_graphson2_row_factory
-
-    # Create a GraphSON2 execution profile
-    ep = GraphExecutionProfile(graph_options=GraphOptions(graph_name='types',
-                                                          graph_protocol=GraphProtocol.GRAPHSON_2_0),
-                               row_factory=graph_graphson2_row_factory)
-
-    cluster = Cluster(execution_profiles={EXEC_PROFILE_GRAPH_DEFAULT: ep})
-    session = cluster.connect()
-    session.execute_graph(...)
-
-Using GraphSON2, all properties will be automatically deserialized to
-its Python representation. Note that it may bring significant
-behavioral change at runtime.
-
-It is generally recommended to switch to GraphSON2 as it brings more
-consistent support for complex data types in the Graph driver and will
-be activated by default in the next major version (Python dse-driver
-driver 3.0).

+DataStax Graph Queries
+======================
+
+The driver executes graph queries over the Cassandra native protocol. Use
+:meth:`.Session.execute_graph` or :meth:`.Session.execute_graph_async` for 
+executing gremlin queries in DataStax Graph.
+
+The driver defines three Execution Profiles suitable for graph execution:
+
+* :data:`~.cluster.EXEC_PROFILE_GRAPH_DEFAULT`
+* :data:`~.cluster.EXEC_PROFILE_GRAPH_SYSTEM_DEFAULT`
+* :data:`~.cluster.EXEC_PROFILE_GRAPH_ANALYTICS_DEFAULT`
+
+See :doc:`getting_started` and :doc:`execution_profiles`
+for more detail on working with profiles.
+
+In DSE 6.8.0, the Core graph engine has been introduced and is now the default. It
+provides a better unified multi-model, performance and scale. This guide
+is for graphs that use the core engine. If you work with previous versions of 
+DSE or existing graphs, see :doc:`classic_graph`.
+
+Getting Started with Graph and the Core Engine
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+First, we need to create a graph in the system. To access the system API, we 
+use the system execution profile ::
+
+    from cassandra.cluster import Cluster, EXEC_PROFILE_GRAPH_SYSTEM_DEFAULT
+
+    cluster = Cluster()
+    session = cluster.connect()
+
+    graph_name = 'movies'
+    session.execute_graph("system.graph(name).create()", {'name': graph_name},
+                          execution_profile=EXEC_PROFILE_GRAPH_SYSTEM_DEFAULT)
+
+
+Graphs that use the core engine only support GraphSON3. Since they are Cassandra tables under
+the hood, we can automatically configure the execution profile with the proper options
+(row_factory and graph_protocol) when executing queries. You only need to make sure that
+the `graph_name` is set and GraphSON3 will be automatically used::
+
+    from cassandra.cluster import Cluster, GraphExecutionProfile, EXEC_PROFILE_GRAPH_DEFAULT
+
+    graph_name = 'movies'
+    ep = GraphExecutionProfile(graph_options=GraphOptions(graph_name=graph_name))
+    cluster = Cluster(execution_profiles={EXEC_PROFILE_GRAPH_DEFAULT: ep})
+    session = cluster.connect()
+    session.execute_graph("g.addV(...)")
+
+
+Note that this graph engine detection is based on the metadata. You might experience
+some query errors if the graph has been newly created and is not yet in the metadata. This
+would result to a badly configured execution profile. If you really want to avoid that,
+configure your execution profile explicitly::
+
+    from cassandra.cluster import Cluster, GraphExecutionProfile, EXEC_PROFILE_GRAPH_DEFAULT
+    from cassandra.graph import GraphOptions, GraphProtocol, graph_graphson3_row_factory
+
+    graph_name = 'movies'
+    ep_graphson3 = GraphExecutionProfile(
+        row_factory=graph_graphson3_row_factory,
+        graph_options=GraphOptions(
+            graph_protocol=GraphProtocol.GRAPHSON_3_0,
+            graph_name=graph_name))
+
+    cluster = Cluster(execution_profiles={'core': ep_graphson3})
+    session = cluster.connect()
+    session.execute_graph("g.addV(...)", execution_profile='core')
+
+
+We are ready to configure our graph schema. We will create a simple one for movies::
+
+    # A Vertex represents a "thing" in the world.
+    # Create the genre vertex
+    query = """
+        schema.vertexLabel('genre')
+            .partitionBy('genreId', Int)

+
+Now that our genre, actor and movie vertices are added, we'll create the relationships (edges) between them::

+
+We are all set. You can now query your graph. Here are some examples::

+    # Find all movies of the genre Drama
+    for r in session.execute_graph("""

+
+Graph Types for the Core Engine
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Here are the supported graph types with their python representations:
+
+============   =================
+DSE Graph      Python Driver
+============   =================
+text           str
+boolean        bool
+bigint         long

+uuid           UUID
+bigdecimal     Decimal
+duration       Duration (cassandra.util)
+inet           str or IPV4Address/IPV6Address (if available)
+timestamp      datetime.datetime
+date           datetime.date
+time           datetime.time
+polygon        Polygon
+point          Point
+linestring     LineString
+blob           bytearray, buffer (PY2), memoryview (PY3), bytes (PY3)
+list           list
+map            dict
+set            set or list
+               (Can return a list due to numerical values returned by Java)
+tuple          tuple
+udt            class or namedtuple
+============   =================
+
+Named Parameters
+~~~~~~~~~~~~~~~~
+
+Named parameters are passed in a dict to :meth:`.cluster.Session.execute_graph`::
+
+    result_set = session.execute_graph('[a, b]', {'a': 1, 'b': 2}, execution_profile=EXEC_PROFILE_GRAPH_SYSTEM_DEFAULT)
+    [r.value for r in result_set]  # [1, 2]
+
+All python types listed in `Graph Types for the Core Engine`_ can be passed as named parameters and will be serialized
+automatically to their graph representation:
+
+Example::
+
+    session.execute_graph("""
+      g.addV('person').
+      property('name', text_value).
+      property('age', integer_value).
+      property('birthday', timestamp_value).
+      property('house_yard', polygon_value).next()
+    """, {
+      'text_value': 'Mike Smith',
+      'integer_value': 34,
+      'timestamp_value': datetime.datetime(1967, 12, 30),
+      'polygon_value': Polygon(((30, 10), (40, 40), (20, 40), (10, 20), (30, 10)))
+    })
+
+
+As with all Execution Profile parameters, graph options can be set in the cluster default (as shown in the first example)
+or specified per execution::
+
+    ep = session.execution_profile_clone_update(EXEC_PROFILE_GRAPH_DEFAULT,
+                                                graph_options=GraphOptions(graph_name='something-else'))
+    session.execute_graph(statement, execution_profile=ep)
+
+CQL collections, Tuple and UDT
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This is a very interesting feature of the core engine: we can use all CQL data types, including
+list, map, set, tuple and udt. Here is an example using all these types::
+
+    query = """
+        schema.type('address')
+            .property('address', Text)
+            .property('city', Text)
+            .property('state', Text)
+            .create();
+    """
+    session.execute_graph(query)
+
+    # It works the same way than normal CQL UDT, so we
+    # can create an udt class and register it
+    class Address(object):
+        def __init__(self, address, city, state):
+            self.address = address
+            self.city = city
+            self.state = state
+
+    session.cluster.register_user_type(graph_name, 'address', Address)
+
+    query = """
+        schema.vertexLabel('person')
+            .partitionBy('personId', Int)
+            .property('address', typeOf('address'))
+            .property('friends', listOf(Text))
+            .property('skills', setOf(Text))
+            .property('scores', mapOf(Text, Int))
+            .property('last_workout', tupleOf(Text, Date))
+            .create()
+    """
+    session.execute_graph(query)
+
+    # insertion example
+    query = """
+         g.addV('person')
+            .property('personId', pid)
+            .property('address', address)
+            .property('friends', friends)
+            .property('skills', skills)
+            .property('scores', scores)
+            .property('last_workout', last_workout)
+            .next()
+    """
+
+    session.execute_graph(query, {
+        'pid': 3,
+        'address': Address('42 Smith St', 'Quebec', 'QC'),
+        'friends': ['Al', 'Mike', 'Cathy'],
+        'skills': {'food', 'fight', 'chess'},
+        'scores': {'math': 98, 'french': 3},
+        'last_workout': ('CrossFit', datetime.date(2018, 11, 20))
+    })
+
+Limitations
+-----------
+
+Since Python is not a strongly-typed language and the UDT/Tuple graphson representation is, you might 
+get schema errors when trying to write numerical data. Example::
+
+    session.execute_graph("""
+        schema.vertexLabel('test_tuple').partitionBy('id', Int).property('t', tupleOf(Text, Bigint)).create()
+    """)
+
+    session.execute_graph("""
+        g.addV('test_tuple').property('id', 0).property('t', t)
+          """, 
+          {'t': ('Test', 99))}
+    )
+
+    # error: [Invalid query] message="Value component 1 is of type int, not bigint"
+
+This is because the server requires the client to include a GraphSON schema definition
+with every UDT or tuple query. In the general case, the driver can't determine what Graph type
+is meant by, e.g., an int value, and so it can't serialize the value with the correct type in the schema.
+The driver provides some numerical type-wrapper factories that you can use to specify types:
+
+* :func:`~.to_int`
+* :func:`~.to_bigint`
+* :func:`~.to_smallint`
+* :func:`~.to_float`
+* :func:`~.to_double`
+
+Here's the working example of the case above::
+
+    from cassandra.graph import to_bigint
+
+     session.execute_graph("""
+        g.addV('test_tuple').property('id', 0).property('t', t)
+          """, 
+          {'t': ('Test', to_bigint(99))}
+    )
+
+Continuous Paging
+~~~~~~~~~~~~~~~~~
+
+This is another nice feature that comes with the core engine: continuous paging with
+graph queries. If all nodes of the cluster are >= DSE 6.8.0, it is automatically
+enabled under the hood to get the best performance. If you want to explicitly
+enable/disable it, you can do it through the execution profile::
+
+    # Disable it
+    ep = GraphExecutionProfile(..., continuous_paging_options=None))
+    cluster = Cluster(execution_profiles={EXEC_PROFILE_GRAPH_DEFAULT: ep})
+
+    # Enable with a custom max_pages option
+    ep = GraphExecutionProfile(...,
+        continuous_paging_options=ContinuousPagingOptions(max_pages=10)))
+    cluster = Cluster(execution_profiles={EXEC_PROFILE_GRAPH_DEFAULT: ep})

 DataStax Graph Queries
 ======================
 
-The driver executes graph queries over the Cassandra native protocol. Use
-:meth:`.Session.execute_graph` or :meth:`.Session.execute_graph_async` for 
-executing gremlin queries in DataStax Graph.
-
-The driver defines three Execution Profiles suitable for graph execution:
-
-* :data:`~.cluster.EXEC_PROFILE_GRAPH_DEFAULT`
-* :data:`~.cluster.EXEC_PROFILE_GRAPH_SYSTEM_DEFAULT`
-* :data:`~.cluster.EXEC_PROFILE_GRAPH_ANALYTICS_DEFAULT`

-In DSE 6.8.0, the Core graph engine has been introduced and is now the default. It
-provides a better unified multi-model, performance and scale. This guide
-is for graphs that use the core engine. If you work with previous versions of 
-DSE or existing graphs, see :doc:`classic_graph`.

-Getting Started with Graph and the Core Engine
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Getting Started
+~~~~~~~~~~~~~~~
 
 First, we need to create a graph in the system. To access the system API, we 
 use the system execution profile ::

     session = cluster.connect()
 
     graph_name = 'movies'

                           execution_profile=EXEC_PROFILE_GRAPH_SYSTEM_DEFAULT)
 
 
-Graphs that use the core engine only support GraphSON3. Since they are Cassandra tables under
-the hood, we can automatically configure the execution profile with the proper options
-(row_factory and graph_protocol) when executing queries. You only need to make sure that
-the `graph_name` is set and GraphSON3 will be automatically used::
-
-    from cassandra.cluster import Cluster, GraphExecutionProfile, EXEC_PROFILE_GRAPH_DEFAULT
-
-    graph_name = 'movies'
-    ep = GraphExecutionProfile(graph_options=GraphOptions(graph_name=graph_name))
-    cluster = Cluster(execution_profiles={EXEC_PROFILE_GRAPH_DEFAULT: ep})
-    session = cluster.connect()
-    session.execute_graph("g.addV(...)")
-
+To execute requests on our newly created graph, we need to setup an execution
+profile. Additionally, we also need to set the schema_mode to `development` 
+for the schema creation::
 
-Note that this graph engine detection is based on the metadata. You might experience
-some query errors if the graph has been newly created and is not yet in the metadata. This
-would result to a badly configured execution profile. If you really want to avoid that,
-configure your execution profile explicitly::
 
     from cassandra.cluster import Cluster, GraphExecutionProfile, EXEC_PROFILE_GRAPH_DEFAULT
-    from cassandra.graph import GraphOptions, GraphProtocol, graph_graphson3_row_factory
+    from cassandra.graph import GraphOptions
 
     graph_name = 'movies'
-    ep_graphson3 = GraphExecutionProfile(
-        row_factory=graph_graphson3_row_factory,
-        graph_options=GraphOptions(
-            graph_protocol=GraphProtocol.GRAPHSON_3_0,
-            graph_name=graph_name))

+Graph Row Factory
+~~~~~~~~~~~~~~~~~
+
+By default (with :class:`.GraphExecutionProfile.row_factory` set to :func:`.graph.graph_object_row_factory`), known graph result
+types are unpacked and returned as specialized types (:class:`.Vertex`, :class:`.Edge`). If the result is not one of these
+types, a :class:`.graph.Result` is returned, containing the graph result parsed from JSON and removed from its outer dict.
+The class has some accessor convenience methods for accessing top-level properties by name (`type`, `properties` above),
+or lists by index::
+
+    # dicts with `__getattr__` or `__getitem__`
+    result = session.execute_graph("[[key_str: 'value', key_int: 3]]", execution_profile=EXEC_PROFILE_GRAPH_SYSTEM_DEFAULT)[0]  # Using system exec just because there is no graph defined
+    result  # dse.graph.Result({u'key_str': u'value', u'key_int': 3})
+    result.value  # {u'key_int': 3, u'key_str': u'value'} (dict)
+    result.key_str  # u'value'
+    result.key_int  # 3
+    result['key_str']  # u'value'
+    result['key_int']  # 3
+
+    # lists with `__getitem__`
+    result = session.execute_graph('[[0, 1, 2]]', execution_profile=EXEC_PROFILE_GRAPH_SYSTEM_DEFAULT)[0]
+    result  # dse.graph.Result([0, 1, 2])
+    result.value  # [0, 1, 2] (list)
+    result[1]  # 1 (list[1])
+
+You can use a different row factory by setting :attr:`.Session.default_graph_row_factory` or passing it to
+:meth:`.Session.execute_graph`. For example, :func:`.graph.single_object_row_factory` returns the JSON result string`,
+unparsed. :func:`.graph.graph_result_row_factory` returns parsed, but unmodified results (such that all metadata is retained,
+unlike :func:`.graph.graph_object_row_factory`, which sheds some as attributes and properties are unpacked). These results
+also provide convenience methods for converting to known types (:meth:`~.Result.as_vertex`, :meth:`~.Result.as_edge`, :meth:`~.Result.as_path`).
+
+Vertex and Edge properties are never unpacked since their types are unknown. If you know your graph schema and want to
+deserialize properties, use the :class:`.GraphSON1Deserializer`. It provides convenient methods to deserialize by types (e.g.
+deserialize_date, deserialize_uuid, deserialize_polygon etc.) Example::
+
+    # ...
+    from cassandra.graph import GraphSON1Deserializer
+
+    row = session.execute_graph("g.V().toList()")[0]
+    value = row.properties['my_property_key'][0].value  # accessing the VertexProperty value
+    value = GraphSON1Deserializer.deserialize_timestamp(value)
+
+    print(value)  # 2017-06-26 08:27:05
+    print(type(value))  # <type 'datetime.datetime'>

-list, map, set, tuple and udt. Here is an example using all these types::
+The default graph protocol used is GraphSON1. However GraphSON1 may
+cause problems of type conversion happening during the serialization
+of the query to the DSE Graph server, or the deserialization of the
+responses back from a string Gremlin query. GraphSON2 offers better
+support for the complex data types handled by DSE Graph.

-Limitations
------------
+DSE >=5.0.4 now offers the possibility to use the GraphSON2 protocol
+for graph queries. Enabling GraphSON2 can be done by `changing the
+graph protocol of the execution profile` and `setting the graphson2 row factory`::
 
-Since Python is not a strongly-typed language and the UDT/Tuple graphson representation is, you might 
-get schema errors when trying to write numerical data. Example::
-
-    session.execute_graph("""
-        schema.vertexLabel('test_tuple').partitionBy('id', Int).property('t', tupleOf(Text, Bigint)).create()
-    """)
-
-    session.execute_graph("""
-        g.addV('test_tuple').property('id', 0).property('t', t)
-          """, 
-          {'t': ('Test', 99))}
-    )
-
-    # error: [Invalid query] message="Value component 1 is of type int, not bigint"
-
-This is because the server requires the client to include a GraphSON schema definition
-with every UDT or tuple query. In the general case, the driver can't determine what Graph type
-is meant by, e.g., an int value, and so it can't serialize the value with the correct type in the schema.
-The driver provides some numerical type-wrapper factories that you can use to specify types:
-
-* :func:`~.to_int`
-* :func:`~.to_bigint`
-* :func:`~.to_smallint`
-* :func:`~.to_float`
-* :func:`~.to_double`
-
-Here's the working example of the case above::
-
-    from cassandra.graph import to_bigint
-
-     session.execute_graph("""
-        g.addV('test_tuple').property('id', 0).property('t', t)
-          """, 
-          {'t': ('Test', to_bigint(99))}
-    )
-
-Continuous Paging
-~~~~~~~~~~~~~~~~~
+    from cassandra.cluster import Cluster, GraphExecutionProfile, EXEC_PROFILE_GRAPH_DEFAULT
+    from cassandra.graph import GraphOptions, GraphProtocol, graph_graphson2_row_factory
 
-This is another nice feature that comes with the core engine: continuous paging with
-graph queries. If all nodes of the cluster are >= DSE 6.8.0, it is automatically
-enabled under the hood to get the best performance. If you want to explicitly
-enable/disable it, you can do it through the execution profile::
+    # Create a GraphSON2 execution profile
+    ep = GraphExecutionProfile(graph_options=GraphOptions(graph_name='types',
+                                                          graph_protocol=GraphProtocol.GRAPHSON_2_0),
+                               row_factory=graph_graphson2_row_factory)
 
-    # Disable it
-    ep = GraphExecutionProfile(..., continuous_paging_options=None))
     cluster = Cluster(execution_profiles={EXEC_PROFILE_GRAPH_DEFAULT: ep})
+    session = cluster.connect()
+    session.execute_graph(...)
 
-    # Enable with a custom max_pages option
-    ep = GraphExecutionProfile(...,
-        continuous_paging_options=ContinuousPagingOptions(max_pages=10)))
-    cluster = Cluster(execution_profiles={EXEC_PROFILE_GRAPH_DEFAULT: ep})
+Using GraphSON2, all properties will be automatically deserialized to
+its Python representation. Note that it may bring significant
+behavioral change at runtime.
+
+It is generally recommended to switch to GraphSON2 as it brings more
+consistent support for complex data types in the Graph driver and will
+be activated by default in the next major version (Python dse-driver
+driver 3.0).

Subject: [PATCH 4292/4528] 4.0 test changes:  - Add TestCluster class to
 integration tests to allow easier setting of default options and updated all
 call points  - Removed setting __defaults__ on stuff  - Changed a bunch of
 '4.0' checks to be '4.0-a'  - Enabled materialized views, sasi, and transient
 replication in standard test startup options  - Updated materialized views to
 specify not null for primary keys as required in 4.0  - Added new protocol
 error message received from 4.0 in test_no_connection_refused_on_timeout

+DataStax Classic Graph Queries
+==============================
+
+Getting Started
+~~~~~~~~~~~~~~~
+
+First, we need to create a graph in the system. To access the system API, we 
+use the system execution profile ::
+
+    from cassandra.cluster import Cluster, EXEC_PROFILE_GRAPH_SYSTEM_DEFAULT
+
+    cluster = Cluster()
+    session = cluster.connect()
+
+    graph_name = 'movies'
+    session.execute_graph("system.graph(name).ifNotExists().engine(Classic).create()", {'name': graph_name},
+                          execution_profile=EXEC_PROFILE_GRAPH_SYSTEM_DEFAULT)
+
+
+To execute requests on our newly created graph, we need to setup an execution
+profile. Additionally, we also need to set the schema_mode to `development` 
+for the schema creation::
+
+
+    from cassandra.cluster import Cluster, GraphExecutionProfile, EXEC_PROFILE_GRAPH_DEFAULT
+    from cassandra.graph import GraphOptions
+
+    graph_name = 'movies'
+    ep = GraphExecutionProfile(graph_options=GraphOptions(graph_name=graph_name))
+
+    cluster = Cluster(execution_profiles={EXEC_PROFILE_GRAPH_DEFAULT: ep})
+    session = cluster.connect()
+    
+    session.execute_graph("schema.config().option('graph.schema_mode').set('development')")
+
+
+We are ready to configure our graph schema. We will create a simple one for movies::
+
+    # properties are used to define a vertex
+    properties = """
+    schema.propertyKey("genreId").Text().create();
+    schema.propertyKey("personId").Text().create();
+    schema.propertyKey("movieId").Text().create();
+    schema.propertyKey("name").Text().create();
+    schema.propertyKey("title").Text().create();
+    schema.propertyKey("year").Int().create();
+    schema.propertyKey("country").Text().create();
+    """
+
+    session.execute_graph(properties)  # we can execute multiple statements in a single request
+
+    # A Vertex represents a "thing" in the world.
+    vertices = """
+    schema.vertexLabel("genre").properties("genreId","name").create();
+    schema.vertexLabel("person").properties("personId","name").create();
+    schema.vertexLabel("movie").properties("movieId","title","year","country").create();
+    """
+
+    session.execute_graph(vertices)
+
+    # An edge represents a relationship between two vertices
+    edges = """
+    schema.edgeLabel("belongsTo").single().connection("movie","genre").create();
+    schema.edgeLabel("actor").connection("movie","person").create();
+    """
+
+    session.execute_graph(edges)
+
+    # Indexes to execute graph requests efficiently
+    indexes = """
+    schema.vertexLabel("genre").index("genresById").materialized().by("genreId").add();
+    schema.vertexLabel("genre").index("genresByName").materialized().by("name").add();

+
+Graph Types
+~~~~~~~~~~~
+
+Here are the supported graph types with their python representations:
+
+==========   ================
+DSE Graph    Python
+==========   ================
+boolean      bool
+bigint       long, int (PY3)
+int          int
+smallint     int
+varint       int
+float        float
+double       double
+uuid         uuid.UUID
+Decimal      Decimal
+inet         str
+timestamp    datetime.datetime
+date         datetime.date
+time         datetime.time
+duration     datetime.timedelta
+point        Point
+linestring   LineString
+polygon      Polygon
+blob         bytearray, buffer (PY2), memoryview (PY3), bytes (PY3)
+==========   ================
+
+Graph Row Factory
+~~~~~~~~~~~~~~~~~
+
+By default (with :class:`.GraphExecutionProfile.row_factory` set to :func:`.graph.graph_object_row_factory`), known graph result
+types are unpacked and returned as specialized types (:class:`.Vertex`, :class:`.Edge`). If the result is not one of these
+types, a :class:`.graph.Result` is returned, containing the graph result parsed from JSON and removed from its outer dict.
+The class has some accessor convenience methods for accessing top-level properties by name (`type`, `properties` above),
+or lists by index::
+
+    # dicts with `__getattr__` or `__getitem__`
+    result = session.execute_graph("[[key_str: 'value', key_int: 3]]", execution_profile=EXEC_PROFILE_GRAPH_SYSTEM_DEFAULT)[0]  # Using system exec just because there is no graph defined
+    result  # dse.graph.Result({u'key_str': u'value', u'key_int': 3})
+    result.value  # {u'key_int': 3, u'key_str': u'value'} (dict)
+    result.key_str  # u'value'
+    result.key_int  # 3
+    result['key_str']  # u'value'
+    result['key_int']  # 3
+
+    # lists with `__getitem__`
+    result = session.execute_graph('[[0, 1, 2]]', execution_profile=EXEC_PROFILE_GRAPH_SYSTEM_DEFAULT)[0]
+    result  # dse.graph.Result([0, 1, 2])
+    result.value  # [0, 1, 2] (list)
+    result[1]  # 1 (list[1])
+
+You can use a different row factory by setting :attr:`.Session.default_graph_row_factory` or passing it to
+:meth:`.Session.execute_graph`. For example, :func:`.graph.single_object_row_factory` returns the JSON result string`,
+unparsed. :func:`.graph.graph_result_row_factory` returns parsed, but unmodified results (such that all metadata is retained,
+unlike :func:`.graph.graph_object_row_factory`, which sheds some as attributes and properties are unpacked). These results
+also provide convenience methods for converting to known types (:meth:`~.Result.as_vertex`, :meth:`~.Result.as_edge`, :meth:`~.Result.as_path`).
+
+Vertex and Edge properties are never unpacked since their types are unknown. If you know your graph schema and want to
+deserialize properties, use the :class:`.GraphSON1Deserializer`. It provides convenient methods to deserialize by types (e.g.
+deserialize_date, deserialize_uuid, deserialize_polygon etc.) Example::
+
+    # ...
+    from cassandra.graph import GraphSON1Deserializer
+
+    row = session.execute_graph("g.V().toList()")[0]
+    value = row.properties['my_property_key'][0].value  # accessing the VertexProperty value
+    value = GraphSON1Deserializer.deserialize_timestamp(value)
+
+    print(value)  # 2017-06-26 08:27:05
+    print(type(value))  # <type 'datetime.datetime'>
+
+
+Named Parameters
+~~~~~~~~~~~~~~~~
+
+Named parameters are passed in a dict to :meth:`.cluster.Session.execute_graph`::
+
+    result_set = session.execute_graph('[a, b]', {'a': 1, 'b': 2}, execution_profile=EXEC_PROFILE_GRAPH_SYSTEM_DEFAULT)
+    [r.value for r in result_set]  # [1, 2]
+
+All python types listed in `Graph Types`_ can be passed as named parameters and will be serialized
+automatically to their graph representation:
+
+Example::
+
+    session.execute_graph("""
+      g.addV('person').
+      property('name', text_value).
+      property('age', integer_value).
+      property('birthday', timestamp_value).
+      property('house_yard', polygon_value).toList()
+    """, {
+      'text_value': 'Mike Smith',
+      'integer_value': 34,
+      'timestamp_value': datetime.datetime(1967, 12, 30),
+      'polygon_value': Polygon(((30, 10), (40, 40), (20, 40), (10, 20), (30, 10)))
+    })
+
+
+As with all Execution Profile parameters, graph options can be set in the cluster default (as shown in the first example)
+or specified per execution::
+
+    ep = session.execution_profile_clone_update(EXEC_PROFILE_GRAPH_DEFAULT,
+                                                graph_options=GraphOptions(graph_name='something-else'))
+    session.execute_graph(statement, execution_profile=ep)
+
+Using GraphSON2 Protocol
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+The default graph protocol used is GraphSON1. However GraphSON1 may
+cause problems of type conversion happening during the serialization
+of the query to the DSE Graph server, or the deserialization of the
+responses back from a string Gremlin query. GraphSON2 offers better
+support for the complex data types handled by DSE Graph.
+
+DSE >=5.0.4 now offers the possibility to use the GraphSON2 protocol
+for graph queries. Enabling GraphSON2 can be done by `changing the
+graph protocol of the execution profile` and `setting the graphson2 row factory`::
+
+    from cassandra.cluster import Cluster, GraphExecutionProfile, EXEC_PROFILE_GRAPH_DEFAULT
+    from cassandra.graph import GraphOptions, GraphProtocol, graph_graphson2_row_factory
+
+    # Create a GraphSON2 execution profile
+    ep = GraphExecutionProfile(graph_options=GraphOptions(graph_name='types',
+                                                          graph_protocol=GraphProtocol.GRAPHSON_2_0),
+                               row_factory=graph_graphson2_row_factory)
+
+    cluster = Cluster(execution_profiles={EXEC_PROFILE_GRAPH_DEFAULT: ep})
+    session = cluster.connect()
+    session.execute_graph(...)
+
+Using GraphSON2, all properties will be automatically deserialized to
+its Python representation. Note that it may bring significant
+behavioral change at runtime.
+
+It is generally recommended to switch to GraphSON2 as it brings more
+consistent support for complex data types in the Graph driver and will
+be activated by default in the next major version (Python dse-driver
+driver 3.0).

-DataStax Graph Queries
-======================
-
-The driver executes graph queries over the Cassandra native protocol. Use
-:meth:`.Session.execute_graph` or :meth:`.Session.execute_graph_async` for 
-executing gremlin queries in DataStax Graph.
-
-The driver defines three Execution Profiles suitable for graph execution:
-
-* :data:`~.cluster.EXEC_PROFILE_GRAPH_DEFAULT`
-* :data:`~.cluster.EXEC_PROFILE_GRAPH_SYSTEM_DEFAULT`
-* :data:`~.cluster.EXEC_PROFILE_GRAPH_ANALYTICS_DEFAULT`
-
-See :doc:`getting_started` and :doc:`execution_profiles`
-for more detail on working with profiles.
-
-In DSE 6.8.0, the Core graph engine has been introduced and is now the default. It
-provides a better unified multi-model, performance and scale. This guide
-is for graphs that use the core engine. If you work with previous versions of 
-DSE or existing graphs, see :doc:`classic_graph`.
-
-Getting Started with Graph and the Core Engine
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-First, we need to create a graph in the system. To access the system API, we 
-use the system execution profile ::
-
-    from cassandra.cluster import Cluster, EXEC_PROFILE_GRAPH_SYSTEM_DEFAULT
-
-    cluster = Cluster()
-    session = cluster.connect()
-
-    graph_name = 'movies'
-    session.execute_graph("system.graph(name).create()", {'name': graph_name},
-                          execution_profile=EXEC_PROFILE_GRAPH_SYSTEM_DEFAULT)
-
-
-Graphs that use the core engine only support GraphSON3. Since they are Cassandra tables under
-the hood, we can automatically configure the execution profile with the proper options
-(row_factory and graph_protocol) when executing queries. You only need to make sure that
-the `graph_name` is set and GraphSON3 will be automatically used::
-
-    from cassandra.cluster import Cluster, GraphExecutionProfile, EXEC_PROFILE_GRAPH_DEFAULT
-
-    graph_name = 'movies'
-    ep = GraphExecutionProfile(graph_options=GraphOptions(graph_name=graph_name))
-    cluster = Cluster(execution_profiles={EXEC_PROFILE_GRAPH_DEFAULT: ep})
-    session = cluster.connect()
-    session.execute_graph("g.addV(...)")
-
-
-Note that this graph engine detection is based on the metadata. You might experience
-some query errors if the graph has been newly created and is not yet in the metadata. This
-would result to a badly configured execution profile. If you really want to avoid that,
-configure your execution profile explicitly::
-
-    from cassandra.cluster import Cluster, GraphExecutionProfile, EXEC_PROFILE_GRAPH_DEFAULT
-    from cassandra.graph import GraphOptions, GraphProtocol, graph_graphson3_row_factory
-
-    graph_name = 'movies'
-    ep_graphson3 = GraphExecutionProfile(
-        row_factory=graph_graphson3_row_factory,
-        graph_options=GraphOptions(
-            graph_protocol=GraphProtocol.GRAPHSON_3_0,
-            graph_name=graph_name))
-
-    cluster = Cluster(execution_profiles={'core': ep_graphson3})
-    session = cluster.connect()
-    session.execute_graph("g.addV(...)", execution_profile='core')
-
-
-We are ready to configure our graph schema. We will create a simple one for movies::
-
-    # A Vertex represents a "thing" in the world.
-    # Create the genre vertex
-    query = """
-        schema.vertexLabel('genre')

-============   =================
-
-Named Parameters
-~~~~~~~~~~~~~~~~
-
-Named parameters are passed in a dict to :meth:`.cluster.Session.execute_graph`::
-
-    result_set = session.execute_graph('[a, b]', {'a': 1, 'b': 2}, execution_profile=EXEC_PROFILE_GRAPH_SYSTEM_DEFAULT)
-    [r.value for r in result_set]  # [1, 2]
-
-All python types listed in `Graph Types for the Core Engine`_ can be passed as named parameters and will be serialized
-automatically to their graph representation:
-
-Example::
-
-    session.execute_graph("""
-      g.addV('person').
-      property('name', text_value).
-      property('age', integer_value).
-      property('birthday', timestamp_value).
-      property('house_yard', polygon_value).next()
-    """, {
-      'text_value': 'Mike Smith',
-      'integer_value': 34,
-      'timestamp_value': datetime.datetime(1967, 12, 30),
-      'polygon_value': Polygon(((30, 10), (40, 40), (20, 40), (10, 20), (30, 10)))
-    })
-
-
-As with all Execution Profile parameters, graph options can be set in the cluster default (as shown in the first example)
-or specified per execution::
-
-    ep = session.execution_profile_clone_update(EXEC_PROFILE_GRAPH_DEFAULT,
-                                                graph_options=GraphOptions(graph_name='something-else'))
-    session.execute_graph(statement, execution_profile=ep)
-
-CQL collections, Tuple and UDT
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-This is a very interesting feature of the core engine: we can use all CQL data types, including
-list, map, set, tuple and udt. Here is an example using all these types::
-
-    query = """
-        schema.type('address')
-            .property('address', Text)
-            .property('city', Text)
-            .property('state', Text)
-            .create();
-    """
-    session.execute_graph(query)
-
-    # It works the same way than normal CQL UDT, so we
-    # can create an udt class and register it
-    class Address(object):
-        def __init__(self, address, city, state):
-            self.address = address
-            self.city = city
-            self.state = state
-
-    session.cluster.register_user_type(graph_name, 'address', Address)
-
-    query = """
-        schema.vertexLabel('person')
-            .partitionBy('personId', Int)
-            .property('address', typeOf('address'))
-            .property('friends', listOf(Text))
-            .property('skills', setOf(Text))
-            .property('scores', mapOf(Text, Int))
-            .property('last_workout', tupleOf(Text, Date))
-            .create()
-    """
-    session.execute_graph(query)
-
-    # insertion example
-    query = """
-         g.addV('person')
-            .property('personId', pid)
-            .property('address', address)
-            .property('friends', friends)
-            .property('skills', skills)
-            .property('scores', scores)
-            .property('last_workout', last_workout)
-            .next()
-    """
-
-    session.execute_graph(query, {
-        'pid': 3,
-        'address': Address('42 Smith St', 'Quebec', 'QC'),
-        'friends': ['Al', 'Mike', 'Cathy'],
-        'skills': {'food', 'fight', 'chess'},
-        'scores': {'math': 98, 'french': 3},
-        'last_workout': ('CrossFit', datetime.date(2018, 11, 20))
-    })
-
-Limitations
------------
-
-Since Python is not a strongly-typed language and the UDT/Tuple graphson representation is, you might 
-get schema errors when trying to write numerical data. Example::
-
-    session.execute_graph("""
-        schema.vertexLabel('test_tuple').partitionBy('id', Int).property('t', tupleOf(Text, Bigint)).create()
-    """)
-
-    session.execute_graph("""
-        g.addV('test_tuple').property('id', 0).property('t', t)
-          """, 
-          {'t': ('Test', 99))}
-    )
-
-    # error: [Invalid query] message="Value component 1 is of type int, not bigint"
-
-This is because the server requires the client to include a GraphSON schema definition
-with every UDT or tuple query. In the general case, the driver can't determine what Graph type
-is meant by, e.g., an int value, and so it can't serialize the value with the correct type in the schema.
-The driver provides some numerical type-wrapper factories that you can use to specify types:
-
-* :func:`~.to_int`
-* :func:`~.to_bigint`
-* :func:`~.to_smallint`
-* :func:`~.to_float`
-* :func:`~.to_double`
-
-Here's the working example of the case above::
-
-    from cassandra.graph import to_bigint
-
-     session.execute_graph("""
-        g.addV('test_tuple').property('id', 0).property('t', t)
-          """, 
-          {'t': ('Test', to_bigint(99))}
-    )
-
-Continuous Paging
-~~~~~~~~~~~~~~~~~
-
-This is another nice feature that comes with the core engine: continuous paging with
-graph queries. If all nodes of the cluster are >= DSE 6.8.0, it is automatically
-enabled under the hood to get the best performance. If you want to explicitly
-enable/disable it, you can do it through the execution profile::
-
-    # Disable it
-    ep = GraphExecutionProfile(..., continuous_paging_options=None))
-    cluster = Cluster(execution_profiles={EXEC_PROFILE_GRAPH_DEFAULT: ep})
-
-    # Enable with a custom max_pages option
-    ep = GraphExecutionProfile(...,
-        continuous_paging_options=ContinuousPagingOptions(max_pages=10)))
-    cluster = Cluster(execution_profiles={EXEC_PROFILE_GRAPH_DEFAULT: ep})

 DataStax Graph Queries
 ======================
 
-Getting Started
-~~~~~~~~~~~~~~~
+The driver executes graph queries over the Cassandra native protocol. Use
+:meth:`.Session.execute_graph` or :meth:`.Session.execute_graph_async` for 
+executing gremlin queries in DataStax Graph.
+
+The driver defines three Execution Profiles suitable for graph execution:
+
+* :data:`~.cluster.EXEC_PROFILE_GRAPH_DEFAULT`
+* :data:`~.cluster.EXEC_PROFILE_GRAPH_SYSTEM_DEFAULT`
+* :data:`~.cluster.EXEC_PROFILE_GRAPH_ANALYTICS_DEFAULT`
+
+See :doc:`getting_started` and :doc:`execution_profiles`
+for more detail on working with profiles.
+
+In DSE 6.8.0, the Core graph engine has been introduced and is now the default. It
+provides a better unified multi-model, performance and scale. This guide
+is for graphs that use the core engine. If you work with previous versions of 
+DSE or existing graphs, see :doc:`classic_graph`.
+
+Getting Started with Graph and the Core Engine
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
 First, we need to create a graph in the system. To access the system API, we 
 use the system execution profile ::

                           execution_profile=EXEC_PROFILE_GRAPH_SYSTEM_DEFAULT)
 
 
-To execute requests on our newly created graph, we need to setup an execution
-profile. Additionally, we also need to set the schema_mode to `development` 
-for the schema creation::
-
+Graphs that use the core engine only support GraphSON3. Since they are Cassandra tables under
+the hood, we can automatically configure the execution profile with the proper options
+(row_factory and graph_protocol) when executing queries. You only need to make sure that
+the `graph_name` is set and GraphSON3 will be automatically used::
 
     from cassandra.cluster import Cluster, GraphExecutionProfile, EXEC_PROFILE_GRAPH_DEFAULT
-    from cassandra.graph import GraphOptions
 
     graph_name = 'movies'
     ep = GraphExecutionProfile(graph_options=GraphOptions(graph_name=graph_name))

+    session.execute_graph("g.addV(...)")
 
 
-We are ready to configure our graph schema. We will create a simple one for movies::
+Note that this graph engine detection is based on the metadata. You might experience
+some query errors if the graph has been newly created and is not yet in the metadata. This
+would result to a badly configured execution profile. If you really want to avoid that,
+configure your execution profile explicitly::

-==========   ================
-
-Graph Row Factory
-~~~~~~~~~~~~~~~~~
-
-By default (with :class:`.GraphExecutionProfile.row_factory` set to :func:`.graph.graph_object_row_factory`), known graph result
-types are unpacked and returned as specialized types (:class:`.Vertex`, :class:`.Edge`). If the result is not one of these
-types, a :class:`.graph.Result` is returned, containing the graph result parsed from JSON and removed from its outer dict.
-The class has some accessor convenience methods for accessing top-level properties by name (`type`, `properties` above),
-or lists by index::
-
-    # dicts with `__getattr__` or `__getitem__`
-    result = session.execute_graph("[[key_str: 'value', key_int: 3]]", execution_profile=EXEC_PROFILE_GRAPH_SYSTEM_DEFAULT)[0]  # Using system exec just because there is no graph defined
-    result  # dse.graph.Result({u'key_str': u'value', u'key_int': 3})
-    result.value  # {u'key_int': 3, u'key_str': u'value'} (dict)
-    result.key_str  # u'value'
-    result.key_int  # 3
-    result['key_str']  # u'value'
-    result['key_int']  # 3
-
-    # lists with `__getitem__`
-    result = session.execute_graph('[[0, 1, 2]]', execution_profile=EXEC_PROFILE_GRAPH_SYSTEM_DEFAULT)[0]
-    result  # dse.graph.Result([0, 1, 2])
-    result.value  # [0, 1, 2] (list)
-    result[1]  # 1 (list[1])
-
-You can use a different row factory by setting :attr:`.Session.default_graph_row_factory` or passing it to
-:meth:`.Session.execute_graph`. For example, :func:`.graph.single_object_row_factory` returns the JSON result string`,
-unparsed. :func:`.graph.graph_result_row_factory` returns parsed, but unmodified results (such that all metadata is retained,
-unlike :func:`.graph.graph_object_row_factory`, which sheds some as attributes and properties are unpacked). These results
-also provide convenience methods for converting to known types (:meth:`~.Result.as_vertex`, :meth:`~.Result.as_edge`, :meth:`~.Result.as_path`).
-
-Vertex and Edge properties are never unpacked since their types are unknown. If you know your graph schema and want to
-deserialize properties, use the :class:`.GraphSON1Deserializer`. It provides convenient methods to deserialize by types (e.g.
-deserialize_date, deserialize_uuid, deserialize_polygon etc.) Example::
-
-    # ...
-    from cassandra.graph import GraphSON1Deserializer
-
-    row = session.execute_graph("g.V().toList()")[0]
-    value = row.properties['my_property_key'][0].value  # accessing the VertexProperty value
-    value = GraphSON1Deserializer.deserialize_timestamp(value)
-
-    print(value)  # 2017-06-26 08:27:05
-    print(type(value))  # <type 'datetime.datetime'>

-The default graph protocol used is GraphSON1. However GraphSON1 may
-cause problems of type conversion happening during the serialization
-of the query to the DSE Graph server, or the deserialization of the
-responses back from a string Gremlin query. GraphSON2 offers better
-support for the complex data types handled by DSE Graph.
+This is a very interesting feature of the core engine: we can use all CQL data types, including
+list, map, set, tuple and udt. Here is an example using all these types::

+Limitations
+-----------
 
-    cluster = Cluster(execution_profiles={EXEC_PROFILE_GRAPH_DEFAULT: ep})
-    session = cluster.connect()
-    session.execute_graph(...)
+Since Python is not a strongly-typed language and the UDT/Tuple graphson representation is, you might 
+get schema errors when trying to write numerical data. Example::
 
-Using GraphSON2, all properties will be automatically deserialized to
-its Python representation. Note that it may bring significant
-behavioral change at runtime.
+    session.execute_graph("""
+        schema.vertexLabel('test_tuple').partitionBy('id', Int).property('t', tupleOf(Text, Bigint)).create()
+    """)
+
+    session.execute_graph("""
+        g.addV('test_tuple').property('id', 0).property('t', t)
+          """, 
+          {'t': ('Test', 99))}
+    )
+
+    # error: [Invalid query] message="Value component 1 is of type int, not bigint"
+
+This is because the server requires the client to include a GraphSON schema definition
+with every UDT or tuple query. In the general case, the driver can't determine what Graph type
+is meant by, e.g., an int value, and so it can't serialize the value with the correct type in the schema.
+The driver provides some numerical type-wrapper factories that you can use to specify types:
+
+* :func:`~.to_int`
+* :func:`~.to_bigint`
+* :func:`~.to_smallint`
+* :func:`~.to_float`
+* :func:`~.to_double`
+
+Here's the working example of the case above::
+
+    from cassandra.graph import to_bigint
 
-It is generally recommended to switch to GraphSON2 as it brings more
-consistent support for complex data types in the Graph driver and will
-be activated by default in the next major version (Python dse-driver
-driver 3.0).
+     session.execute_graph("""
+        g.addV('test_tuple').property('id', 0).property('t', t)
+          """, 
+          {'t': ('Test', to_bigint(99))}
+    )
+
+Continuous Paging
+~~~~~~~~~~~~~~~~~
+
+This is another nice feature that comes with the core engine: continuous paging with
+graph queries. If all nodes of the cluster are >= DSE 6.8.0, it is automatically
+enabled under the hood to get the best performance. If you want to explicitly
+enable/disable it, you can do it through the execution profile::
+
+    # Disable it
+    ep = GraphExecutionProfile(..., continuous_paging_options=None))
+    cluster = Cluster(execution_profiles={EXEC_PROFILE_GRAPH_DEFAULT: ep})
+
+    # Enable with a custom max_pages option
+    ep = GraphExecutionProfile(...,
+        continuous_paging_options=ContinuousPagingOptions(max_pages=10)))
+    cluster = Cluster(execution_profiles={EXEC_PROFILE_GRAPH_DEFAULT: ep})

Subject: [PATCH 4356/4528] Don't create Cluster with hosts if having cloud
 config

We set out to build a Flask app that talks to Astra.
The CQL plugin we used turned out to be crashing if we didn't give it hosts to connect to (https://github.com/thegeorgeous/flask-cqlalchemy/blob/master/flask_cqlalchemy/__init__.py#L48).
But we also had to use the `cloud` key to pass in Astra credentials (via `setup_kwargs` nearby the link above).
This exploded on us in cqlengine.connection#setup() where the hosts passed into Cluster() made that constructor blow up because:
`ValueError: contact_points, endpoint_factory, ssl_context, and ssl_options cannot be specified with a cloud configuration`

We're not sure this is the right place to patch, but it helped us at least. We figured coming out with a patch directly, instead of an issue, might save some time.

 ^^^^^^^^^^^
 Evenlet isn't yet supported for python 3.7+ due to an `issue in Eventlet <https://github.com/eventlet/eventlet/issues/526>`_.

+
+CqlEngine
+=========
+
+When using the object mapper, you can configure cqlengine with :func:`~.cqlengine.connection.set_session`:
+
+.. code:: python
+
+  from cassandra.cqlengine import connection
+  ...
+
+  c = Cluster(cloud={'secure_connect_bundle':'/path/to/secure-connect-test.zip'},
+              auth_provider=PlainTextAuthProvider('user', 'pass'))
+  s = c.connect('myastrakeyspace')
+  connection.set_session(s)
+  ...
+
+If you are using some third-party libraries (flask, django, etc.), you might not be able to change the
+configuration mechanism. For this reason, the `hosts` argument of the default
+:func:`~.cqlengine.connection.setup` function will be ignored if a `cloud` config is provided:
+
+.. code:: python
+
+  from cassandra.cqlengine import connection
+  ...
+
+  connection.setup(
+    None,  # or anything else
+    "myastrakeyspace", cloud={
+      'secure_connect_bundle':'/path/to/secure-connect-test.zip'
+    },

Subject: [PATCH 4373/4528] Fixes to the Travis build. (#1111)

These fixes were originally implemented by user tbbharaj in https://github.com/datastax/python-driver/pull/1108.
Extracting them into their own PR since 1108 is still being worked and I'd very much like to benefit from this
work across _all_ PRs against python-driver.

Major thanks to tbbharaj for the original work here.

 numberly/fix_empty_paging

This commit provides a fix to the situation when iterating on a
ResultSet, the driver aborts the iteration if the server returns
an empty page even if there are next pages available.

Python driver is affected by the same problem as JAVA-2934
This fix is similar to https://github.com/datastax/java-driver/pull/1544

Subject: [PATCH 4378/4528] Merge pull request #1114 from haaawk/stream_ids_fix

Stop reusing stream ids of requests that have timed out due to client-side timeout (#1114)

* ResponseFuture: do not return the stream ID on client timeout

When a timeout occurs, the ResponseFuture associated with the query
returns its stream ID to the associated connection's free stream ID pool
- so that the stream ID can be immediately reused by another query.

However, that it incorrect and dangerous. If query A times out before it
receives a response from the cluster, a different query B might be
issued on the same connection and stream. If response for query A
arrives earlier than the response for query B, the first one might be
misinterpreted as the response for query B.

This commit changes the logic so that stream IDs are not returned on
timeout - now, they are only returned after receiving a response.

* Connection: fix tracking of in_flight requests

This commit fixes tracking of in_flight requests. Before it, in case of
a client-side timeout, the response ID was not returned to the pool, but
the in_flight counter was decremented anyway. This counter is used to
determine if there is a need to wait for stream IDs to be freed -
without this patch, it could happen that the driver throught that it can
initiate another request due to in_flight counter being low, but there
weren't any free stream IDs to allocate, so an assertion was triggered
and the connection was defuncted and opened again.

Now, requests timed out on the client side are tracked in the
orphaned_request_ids field, and the in_flight counter is decremented
only after the response is received.

* Connection: notify owning pool about released orphaned streams

Before this patch, the following situation could occur:

1. On a single connection, multiple requests are spawned up to the
   maximum concurrency,
2. We want to issue more requests but we need to wait on a condition
   variable because requests spawned in 1. took all stream IDs and we
   need to wait until some of them are freed,
3. All requests from point 1. time out on the client side - we cannot
   free their stream IDs until the database node responds,
4. Responses for requests issued in point 1. arrive, but the Connection
   class has no access to the condition variable mentioned in point 2.,
   so no requests from point 2. are admitted,
5. Requests from point 2. waiting on the condition variable time out
   despite there are stream IDs available.

This commit adds an _on_orphaned_stream_released field to the Connection class, and now
it notifies the owning pool in case a timed out request receives a late
response and a stream ID is freed by calling _on_orphaned_stream_released
callback.

* HostConnection: implement replacing overloaded connections

In a situation of very high overload or poor networking conditions, it
might happen that there is a large number of outstanding requests on a
single connection. Each request reserves a stream ID which cannot be
reused until a response for it arrives, even if the request already
timed out on the client side. Because the pool of available stream IDs
for a single connection is limited, such situation might cause the set
of free stream IDs to shrink to a very small size (including zero),
which will drastically reduce the available concurrency on
the connection, or even render it unusable for some time.

In order to prevent this, the following strategy is adopted: when the
number of orphaned stream IDs reaches a certain threshold (e.g. 75% of
all available stream IDs), the connection becomes marked as overloaded.
Meanwhile, a new connection is opened - when it becomes available, it
replaces the old one, and the old connection is moved to "trash" where
it waits until all its outstanding requests either respond or time out.

This feature is implemented for HostConnection but not for
HostConnectionPool, which means that it will only work for clusters
which use protocol v3 or newer.

This fix is heavily inspired by the fix for JAVA-1519.

+Column Encryption
+=================
+
+Overview
+--------
+Support for client-side encryption of data was added in version 3.27.0 of the Python driver.  When using 
+this feature data will be encrypted on-the-fly according to a specified :class:`~.ColumnEncryptionPolicy`
+instance.  This policy is also used to decrypt data in returned rows.  If a prepared statement is used
+this decryption is transparent to the user; retrieved data will be decrypted and converted into the original
+type (according to definitions in the encryption policy).  Support for simple (i.e. non-prepared) queries is 
+also available, although in this case values must be manually encrypted and/or decrypted.  The 
+:class:`~.ColumnEncryptionPolicy` instance provides methods to assist with these operations.
+
+Client-side encryption and decryption should work against all versions of Cassandra and DSE.  It does not
+utilize any server-side functionality to do its work.
+
+Configuration
+-------------
+Client-side encryption is enabled by creating an instance of a subclass of :class:`~.ColumnEncryptionPolicy`
+and adding information about columns to be encrypted to it.  This policy is then supplied to :class:`~.Cluster`
+when it's created.
+
+.. code-block:: python
+    import os
+
+    from cassandra.policies import ColDesc, AES256ColumnEncryptionPolicy, AES256_KEY_SIZE_BYTES
+
+    key = os.urandom(AES256_KEY_SIZE_BYTES)
+    cl_policy = AES256ColumnEncryptionPolicy()
+    col_desc = ColDesc('ks1','table1','column1')
+    cql_type = "int"
+    cl_policy.add_column(col_desc, key, cql_type)
+    cluster = Cluster(column_encryption_policy=cl_policy)
+
+:class:`~.AES256ColumnEncryptionPolicy` is a subclass of :class:`~.ColumnEncryptionPolicy` which provides 
+encryption and decryption via AES-256.  This class is currently the only available column encryption policy 
+implementation, although users can certainly implement their own by subclassing :class:`~.ColumnEncryptionPolicy`.
+
+:class:`~.ColDesc` is a named tuple which uniquely identifies a column in a given keyspace and table.  When we
+have this tuple, the encryption key and the CQL type contained by this column we can add the column to the policy
+using :func:`~.ColumnEncryptionPolicy.add_column`.  Once we have added all column definitions to the policy we
+pass it along to the cluster.
+
+The CQL type for the column only has meaning at the client; it is never sent to Cassandra.  The encryption key 
+is also never sent to the server; all the server ever sees are random bytes reflecting the encrypted data.  As a
+result all columns containing client-side encrypted values should be declared with the CQL type "blob" at the 
+Cassandra server.
+
+Usage
+-----
+
+Encryption
+^^^^^^^^^^
+Client-side encryption shines most when used with prepared statements.  A prepared statement is aware of information 
+about the columns in the query it was built from and we can use this information to transparently encrypt any
+supplied parameters.  For example, we can create a prepared statement to insert a value into column1 (as defined above)
+by executing the following code after creating a :class:`~.Cluster` in the manner described above:
+
+.. code-block:: python
+    session = cluster.connect()
+    prepared = session.prepare("insert into ks1.table1 (column1) values (?)")
+    session.execute(prepared, (1000,))
+
+Our encryption policy will detect that "column1" is an encrypted column and take appropriate action.
+
+As mentioned above client-side encryption can also be used with simple queries, although such use cases are
+certainly not transparent.  :class:`~.ColumnEncryptionPolicy` provides a helper named
+:func:`~.ColumnEncryptionPolicy.encode_and_encrypt` which will convert an input value into bytes using the
+standard serialization methods employed by the driver.  The result is then encrypted according to the configuration
+of the policy.  Using this approach the example above could be implemented along the lines of the following:
+
+.. code-block:: python
+    session = cluster.connect()
+    session.execute("insert into ks1.table1 (column1) values (%s)",(cl_policy.encode_and_encrypt(col_desc, 1000),))
+
+Decryption
+^^^^^^^^^^
+Decryption of values returned from the server is always transparent.  Whether we're executing a simple or prepared
+statement encrypted columns will be decrypted automatically and made available via rows just like any other
+result.
+
+Limitations
+-----------
+:class:`~.AES256ColumnEncryptionPolicy` uses the implementation of AES-256 provided by the 
+`cryptography <https://cryptography.io/en/latest/>`_ module.  Any limitations of this module should be considered
+when deploying client-side encryption.  Note specifically that a Rust compiler is required for modern versions
+of the cryptography package, although wheels exist for many common platforms.
+
+Client-side encryption has been implemented for both the default Cython and pure Python row processing logic.
+This functionality has not yet been ported to the NumPy Cython implementation.  We have reason to believe the
+NumPy processing works reasonably well on Python 3.7 but fails for Python 3.8.  We hope to address this discrepancy
+in a future release.

+--------------------------------------------------
+The driver has built-in support for client-side encryption and
+decryption of data. For more, see :doc:`column_encryption`.  
+
+CLE depends on the Python `cryptography <https://cryptography.io/en/latest/>`_ module. 
+When installing Python driver 3.27.0. the `cryptography` module is 
+also downloaded and installed.
+If you are using Python driver 3.28.0 or later and want to use CLE, you must
+install the `cryptography <https://cryptography.io/en/latest/>`_ module.
+
+You can install this module along with the driver by specifying the `cle` extra::
+
+    pip install cassandra-driver[cle]
+
+Alternatively, you can also install the module directly via `pip`::
+
+    pip install cryptography
+
+Any version of cryptography >= 35.0 will work for the CLE feature.  You can find additional
+details at `PYTHON-1351 <https://datastax-oss.atlassian.net/browse/PYTHON-1351>`_

 Client-side encryption and decryption should work against all versions of Cassandra and DSE.  It does not
 utilize any server-side functionality to do its work.
 
+WARNING: Consider upgrading to 3.28.0 or later
+------------------------------------------------
+There is a significant issue with the column encryption functionality in Python driver 3.27.0.
+To be able to decrypt your data, you must preserve the cipher initialization vector (IV) used by 
+the :class:`~.AES256ColumnEncryptionPolicy` when your data was written.
+To decrypt your data, you must supply this IV when creating a policy to read this data.
+If you do not supply this IV in the policy to read this data, you will **NOT BE ABLE TO DECRYPT YOUR DATA**. 
+See 
+`PYTHON-1350 <https://datastax-oss.atlassian.net/browse/PYTHON-1350>`_ for more detail. 
+
+DataStax recommends upgrading to Python driver 3.28.0 or later to avoid this issue. 3.28.0 or later manages the IV automatically.  
+Because of this change in functionality, any encrypted data written in 3.27.0 will **NOT** be readable by 3.28.0 or later. 
+After upgrading to Python driver 3.28.0 or later, it is critical that you re-encrypt your data with the new driver version.
+
 Configuration
 -------------
 Client-side encryption is enabled by creating an instance of a subclass of :class:`~.ColumnEncryptionPolicy`

-WARNING: Consider upgrading to 3.28.0 or later
+WARNING: Encryption format changes in 3.28.0
 ------------------------------------------------
-There is a significant issue with the column encryption functionality in Python driver 3.27.0.
-To be able to decrypt your data, you must preserve the cipher initialization vector (IV) used by 
-the :class:`~.AES256ColumnEncryptionPolicy` when your data was written.
-To decrypt your data, you must supply this IV when creating a policy to read this data.
-If you do not supply this IV in the policy to read this data, you will **NOT BE ABLE TO DECRYPT YOUR DATA**. 
-See 
-`PYTHON-1350 <https://datastax-oss.atlassian.net/browse/PYTHON-1350>`_ for more detail. 
-
-DataStax recommends upgrading to Python driver 3.28.0 or later to avoid this issue. 3.28.0 or later manages the IV automatically.  
-Because of this change in functionality, any encrypted data written in 3.27.0 will **NOT** be readable by 3.28.0 or later. 
-After upgrading to Python driver 3.28.0 or later, it is critical that you re-encrypt your data with the new driver version.
+Python driver 3.28.0 introduces a new encryption format for data written by :class:`~.AES256ColumnEncryptionPolicy`.
+As a result, any encrypted data written by Python driver 3.27.0 will **NOT** be readable.
+If you upgraded from 3.27.0, you should re-encrypt your data with 3.28.0.

Subject: [PATCH 4443/4528] Jenkins using new python versions in the matrix
 (#1174)

* update Jenkins matrix to use available python versions in the latest runner image

* Use earliest and latest supported python runtimes for smoke test

* Remove C* and DSE versions that are EOL'ed

* make ccm-private work with python 3.10+

* use pynose to replace nosetests so that it can run under Python 3.10+, before PYTHON-1297 gets merged

 Design and Implementation Guidelines
 ------------------------------------
-- We support Python 2.7+, so any changes must work in any of these runtimes (we use ``six``, ``futures``, and some internal backports for compatability)
 - We have integrations (notably Cassandra cqlsh) that require pure Python and minimal external dependencies. We try to avoid new external dependencies. Where compiled extensions are concerned, there should always be a pure Python fallback implementation.
 - This project follows `semantic versioning <http://semver.org/>`_, so breaking API changes will only be introduced in major versions.
 - Legacy ``cqlengine`` has varying degrees of overreaching client-side validation. Going forward, we will avoid client validation where server feedback is adequate and not overly expensive.

Subject: [PATCH 4475/4528] use timezone-aware API to avoid deprecated warning
 (#1213)

before this change, when testing with cqlsh, we have warnings like:

```
  <frozen importlib._bootstrap>:488: DeprecationWarning: datetime.datetime.utcfromtimestamp() is deprecated and scheduled for removal in a future version. Use timezone-aware objects to represent datetimes in UTC: datetime.datetime.fromtimestamp(timestamp, datetime.UTC).
````

in this change, we replace the deprecated API with timezone-aware API,
to avoid this warning.

to keep the backward compatibility, `DateTime.to_python()` still
returns an offset-naive timestamp.

@@ -135,49 +135,38 @@ Running Unit Tests
 ------------------
 Unit tests can be run like so::
 
-    nosetests -w tests/unit/
+    pytest tests/unit/
 
 You can run a specific test method like so::
 
-    nosetests -w tests/unit/test_connection.py:ConnectionTest.test_bad_protocol_version
+    pytest tests/unit/test_connection.py::ConnectionTest::test_bad_protocol_version
 
 Running Integration Tests
 -------------------------
 In order to run integration tests, you must specify a version to run using the ``CASSANDRA_VERSION`` or ``DSE_VERSION`` environment variable::
 
-    CASSANDRA_VERSION=2.0.9 nosetests -w tests/integration/standard
+    CASSANDRA_VERSION=2.0.9 pytest tests/integration/standard
 
 Or you can specify a cassandra directory (to test unreleased versions)::
 
-    CASSANDRA_DIR=/home/thobbs/cassandra nosetests -w tests/integration/standard/
+    CASSANDRA_DIR=/path/to/cassandra pytest tests/integration/standard/
 
 Specifying the usage of an already running Cassandra cluster
 ------------------------------------------------------------
 The test will start the appropriate Cassandra clusters when necessary  but if you don't want this to happen because a Cassandra cluster is already running the flag ``USE_CASS_EXTERNAL`` can be used, for example::
 
-    USE_CASS_EXTERNAL=1 CASSANDRA_VERSION=2.0.9 nosetests -w tests/integration/standard
+    USE_CASS_EXTERNAL=1 CASSANDRA_VERSION=2.0.9 pytest tests/integration/standard
 
 Specify a Protocol Version for Tests
 ------------------------------------
 The protocol version defaults to 1 for cassandra 1.2 and 2 otherwise.  You can explicitly set
 it with the ``PROTOCOL_VERSION`` environment variable::
 
-    PROTOCOL_VERSION=3 nosetests -w tests/integration/standard
-
-Seeing Test Logs in Real Time
------------------------------
-Sometimes it's useful to output logs for the tests as they run::
-
-    nosetests -w tests/unit/ --nocapture --nologcapture
-
-Use tee to capture logs and see them on your terminal::
-
-    nosetests -w tests/unit/ --nocapture --nologcapture 2>&1 | tee test.log
+    PROTOCOL_VERSION=3 pytest tests/integration/standard
 
 Testing Multiple Python Versions
 --------------------------------
-Use tox to test all of Python 3.8 through 3.12 and pypy (this is what
-TravisCI runs)::

   Dse: All dse server versions.
+  Hcd: All hcd server versions.
   Smoke: CI-friendly configurations. Currently-supported Python version + modern Cassandra/DSE instances.
          We also avoid cython since it's tested as part of the nightlies

-Building the Docs
-=================
-Sphinx is required to build the docs. You probably want to install through apt,
-if possible::
-
-    sudo apt-get install python-sphinx
-
-pip may also work::
-
-    sudo pip install -U Sphinx
-
-To build the docs, run::
-
-    python setup.py doc
-
-Upload the Docs
-=================
-
-This is deprecated. The docs is now only published on https://docs.datastax.com.
-
-To upload the docs, checkout the ``gh-pages`` branch and copy the entire
-contents all of ``docs/_build/X.Y.Z/*`` into the root of the ``gh-pages`` branch
-and then push that branch to github.
-
-For example::
-
-    git checkout 1.0.0
-    python setup.py doc
-    git checkout gh-pages
-    cp -R docs/_build/1.0.0/* .
-    git add --update  # add modified files
-    # Also make sure to add any new documentation files!
-    git commit -m 'Update docs (version 1.0.0)'
-    git push origin gh-pages
-
-If docs build includes errors, those errors may not show up in the next build unless
-you have changed the files with errors.  It's good to occassionally clear the build
-directory and build from scratch::
-
-    rm -rf docs/_build/*
-
-Documentor
-==========
-We now also use another tool called Documentor with Sphinx source to build docs.
-This gives us versioned docs with nice integrated search. This is a private tool
-of DataStax.
-
-Dependencies
-------------
-Sphinx
-~~~~~~
-Installed as described above
-
-Documentor
-~~~~~~~~~~
-Clone and setup Documentor as specified in `the project <https://github.com/riptano/documentor#installation-and-quick-start>`_.
-This tool assumes Ruby, bundler, and npm are present.
-
-Building
---------
-The setup script expects documentor to be in the system path. You can either add it permanently or run with something
-like this::
-
-    PATH=$PATH:<documentor repo>/bin python setup.py doc
-
-The docs will not display properly just browsing the filesystem in a browser. To view the docs as they would be in most
-web servers, use the SimpleHTTPServer module::
-
-    cd docs/_build/
-    python -m SimpleHTTPServer
-
-Then, browse to `localhost:8000 <http://localhost:8000>`_.

Subject: [PATCH 4512/4528] PYTHON-1354 do not set timeout to None when calling
 execute_async in execute_concurrent

The default timeout=_NOT_SET will use the request_timeout specified in
the execution_profile. This is not the same as setting the timeout to
None. This will instead result in having no timeout which is not ideal.
If this behaviour really is wanted, the request_timeout can be set to
None in the execution_profile instead.

-
-    from ez_setup import use_setuptools

-
-If you want to require a specific version of setuptools, set a download
-mirror, or use an alternate download directory, you can do so by supplying

 Supported Event Loops
 ^^^^^^^^^^^^^^^^^^^^^
-For Python versions before 3.12 the driver uses the ``asyncore`` module for its default
-event loop.  Other event loops such as ``libev``, ``gevent`` and ``eventlet`` are also
-available via Python modules or C extensions.  Python 3.12 has removed ``asyncore`` entirely
-so for this platform one of these other event loops must be used.
+The ``asyncore`` and ``libev`` event loops are proven production-grade event loops.  Python 3.12 removed
+asyncore from the runtime but this event loop can still be used in newer versions of Python via the
+`pyasyncore <https://pypi.org/project/pyasyncore/>`_ package.
+
+The ``asyncio`` event loop is generally functional but still somewhat experimental and not recommended
+for production systems.  We anticipate significant improvements to this event loop (including hopefully
+making this event loop the default going forward) in 3.31.0.
+
+The ``gevent``, ``eventlet`` and ``Twisted`` event loops have been deprecated in 3.30.0 and will be removed
+completely in 3.31.0.

+Upgrading to 3.30.0
+-------------------
+Version 3.30.0 of the Python driver is the first release since the driver's donation
+to the Apache Software Foundation (ASF).
+
+Supported Python Versions
+^^^^^^^^^^^^^^^^^^^^^^^^^
+An individual version of the Python driver aims to officially support all Python runtimes
+that are not end-of-life (EOL) at the time of that version's release.  For 3.30.0 this policy
+entails support for Python 3.10 through Python 3.14.  The driver will likely continue to work
+reasonably well on older Python runtimes but only these versions are officially supported.
+
+Conversion to pyproject.toml
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+With this release we are moving away from the install and configuration process based on
+setup.py and towards the use of pyproject.toml.  As a result of this change (and in keeping
+with the typical use of pyproject.toml) configuration of a driver build is now declarative.  All
+build options should be specified in pyproject.toml and overrides via command-line flags or
+environment variables are no longer supported.  Please consult
+`CASSPYTHON-7 <https://issues.apache.org/jira/browse/CASSPYTHON-7>`_ for additional details.
+
+Event Loop Deprecation
+^^^^^^^^^^^^^^^^^^^^^^
+With this release the eventlet, gevent and Twisted event loops are considered deprecated.  Use
+of these event loops in this version will generate a warning to this effect.  We are planning on
+removing these event loops in their entirety in the next minor release.  Please consult
+`CASSPYTHON-12 <https://issues.apache.org/jira/browse/CASSPYTHON-12>`_ for additional details.
+
+Removal of Win32 Wheels
+^^^^^^^^^^^^^^^^^^^^^^^
+As of this release we will no longer be offering wheels for Win32 platforms.  Wheels for other
+Windows platforms will continue to be deployed to PyPI.  Please consult
+`CASSPYTHON-5 <https://issues.apache.org/jira/browse/CASSPYTHON-5>`_ for additional details.
+
+Change to DRIVER_NAME in STARTUP Messages
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+The DRIVER_NAME property in STARTUP messages has been changed in this release to allow
+administrators to clearly distinguish between uses of the previous DataStax Python drivers
+and this driver.  Any monitoring/management applications which were monitoring driver usage
+based on this string should be aware of this change and update accordingly.  Please consult
+`CASSPYTHON-17 <https://issues.apache.org/jira/browse/CASSPYTHON-17>`_ for additional details.
+
+
 Upgrading from dse-driver
 -------------------------
-
 Since 3.21.0, cassandra-driver fully supports DataStax products. dse-driver and
 dse-graph users should now migrate to cassandra-driver to benefit from latest bug fixes
 and new features. The upgrade to this new unified driver version is straightforward
