Package Classes (2.21.2)

Summary of entries of Classes for pubsub.

Classes

Client

A publisher client for Google Cloud Pub/Sub.

This creates an object that is capable of publishing messages. Generally, you can instantiate this client with no arguments, and you get sensible defaults.

Future

This future object is returned from asychronous Pub/Sub publishing calls.

Calling result will resolve the future by returning the message ID, unless an error occurs.

Client

A subscriber client for Google Cloud Pub/Sub.

This creates an object that is capable of subscribing to messages. Generally, you can instantiate this client with no arguments, and you get sensible defaults.

Future

This future object is for subscribe-side calls.

Calling result will resolve the future by returning the message ID, unless an error occurs.

StreamingPullFuture

Represents a process that asynchronously performs streaming pull and schedules messages to be processed.

This future is resolved when the process is stopped (via cancel) or if it encounters an unrecoverable error. Calling .result() will cause the calling thread to block indefinitely.

Message

A representation of a single Pub/Sub message.

The common way to interact with .pubsub_v1.subscriber.message.Message objects is to receive them in callbacks on subscriptions; most users should never have a need to instantiate them by hand. (The exception to this is if you are implementing a custom subclass to .pubsub_v1.subscriber._consumer.Consumer.)

Scheduler

Abstract base class for schedulers.

Schedulers are used to schedule callbacks asynchronously.

ThreadScheduler

A thread pool-based scheduler. It must not be shared across SubscriberClients.

This scheduler is useful in typical I/O-bound message processing.

AcknowledgeRequest

Request for the Acknowledge method.

BigQueryConfig

Configuration for a BigQuery subscription.

State

Possible states for a BigQuery subscription.

    -  Pub/Sub SA has not been granted the `appropriate BigQuery
       IAM
       permissions <https://cloud.google.com/pubsub/docs/create-subscription#assign_bigquery_service_account>`__
    -  bigquery.googleapis.com API is not enabled for the
       project
       (`instructions <https://cloud.google.com/service-usage/docs/enable-disable>`__)
NOT_FOUND (3):
    Cannot write to the BigQuery table because it
    does not exist.
SCHEMA_MISMATCH (4):
    Cannot write to the BigQuery table due to a
    schema mismatch.

    is set to true and the destination locations are not in the
    allowed regions.

API documentation for pubsub_v1.types.BindingDelta class.

CloudStorageConfig

Configuration for a Cloud Storage subscription.

This message has oneof_ fields (mutually exclusive fields). For each oneof, at most one member field can be set at the same time. Setting any member of the oneof automatically clears all other members.
