CreateSubscription

Creates a subscription to a given topic. See the [resource name rules] (https://cloud.google.com/pubsub/docs/pubsub-basics#resource_names). If the subscription already exists, returns `ALREADY_EXISTS`. If the corresponding topic doesn't exist, returns `NOT_FOUND`. + *

If the name is not provided in the request, the server will assign a random name for this subscription on the same project as the topic, conforming to the [resource name format] (https://cloud.google.com/pubsub/docs/pubsub-basics#resource_names). The generated name is populated in the returned Subscription object. Note that for REST API requests, you must specify a name in the request.

 + *

Request object method variants only take one parameter, a request object, which must be constructed before the call.

"Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method.

ModifyAckDeadline

Modifies the ack deadline for a specific message.

StreamingPull

Establishes a stream with the server, which sends messages down to the client. The client streams acknowledgments and ack deadline modifications back to the server. The server will close the stream and return the status on any error. The server may close the stream with status `UNAVAILABLE` to reassign server-side resources, in which case, the client should re-establish the stream. Flow control can be achieved by configuring the underlying RPC channel.

Modifies the `PushConfig` for a specified subscription. + *

This may be used to change a push subscription to a pull one (signified by an empty `PushConfig`) or vice versa, or change the endpoint URL and other attributes of a push subscription. Messages will accumulate for delivery continuously through the call regardless of changes to the `PushConfig`.

Creates a snapshot from the requested subscription. Snapshots are used in [Seek](https://cloud.google.com/pubsub/docs/replay-overview) operations, which allow you to manage message acknowledgments in bulk. That is, you can set the acknowledgment state of messages in an existing subscription to the state captured by a snapshot. If the snapshot already exists, returns `ALREADY_EXISTS`. If the requested subscription doesn't exist, returns `NOT_FOUND`. If the backlog in the subscription is too old -- and the resulting snapshot would expire in less than 1 hour -- then `FAILED_PRECONDITION` is returned. See also the `Snapshot.expire_time` field. If the name is not provided in the request, the server will assign a random name for this snapshot on the same project as the subscription, conforming to the [resource name format] (https://cloud.google.com/pubsub/docs/pubsub-basics#resource_names). The generated name is populated in the returned Snapshot object. Note that for REST API requests, you must specify a name in the request.
