      labels:
          Cloud Labels are a flexible and lightweight mechanism for
          organizing cloud resources into groups that reflect a
          customer's organizational needs and deployment strategies.
          Cloud Labels can be used to filter collections of resources.
          They can be used to control how resource metrics are
          aggregated. And they can be used as arguments to policy
          management rules (e.g. route, firewall, load balancing, etc.).
          -  Label keys must be between 1 and 63 characters long and
          must conform    to the following regular expression:
          ``[a-z]([-a-z0-9]*[a-z0-9])?``. -  Label values must be
          between 0 and 63 characters long and must    conform to the
          regular expression ``([a-z]([-a-z0-9]*[a-z0-9])?)?``. -  No
          more than 64 labels can be associated with a given resource.
          See https://goo.gl/xmQnxf for more information on and examples
          of labels.  If you plan to use labels in your own code, please
          note that additional characters may be allowed in the future.
          And so you are advised to use an internal label
          representation, such as JSON, which doesn't rely upon specific
          characters being disallowed. For example, representing labels
          as the string: name + "*" + value would prove problematic if
          we were to allow "*" in a future release.

          "howl". -  ``name:HOWL`` --> Equivalent to above. -
          ``NAME:howl`` --> Equivalent to above. -  ``labels.env:*`` -->
          The instance has the label "env". -  ``labels.env:dev`` -->
          The instance has the label "env" and the value    of the label
          contains the string "dev". -  ``name:howl labels.env:dev`` -->
          The instance's name contains "howl"    and it has the label

    """Cloud Spanner Instance Admin API

    The Cloud Spanner Instance Admin API can be used to create, delete,
    modify and list instances. Instances are dedicated Cloud Spanner serving
    and storage resources to be used by Cloud Spanner databases.

    Each instance has a "configuration", which dictates where the
    serving resources for the Cloud Spanner instance are located (e.g.,
    US-central, Europe). Configurations are created by Google based on
    resource availability.

    Cloud Spanner billing is based on the instances that exist and their
    sizes. After an instance exists, there are no additional
    per-database or per-operation charges for use of the instance
    (though there may be additional network bandwidth charges).
    Instances offer isolation: problems with databases in one instance
    will not affect other instances. However, within an instance
    databases can affect each other. For example, if one database in an
    instance receives a lot of requests and consumes most of the
    instance resources, fewer resources are available for other
    databases in that instance, and their performance may suffer.
