Class AsyncPublisherClient (1.11.1)

See more code actions.
AsyncPublisherClient(
    *,
    per_partition_batching_settings: typing.Optional[
        google.cloud.pubsub_v1.types.BatchSettings
    ] = None,
    credentials: typing.Optional[google.auth.credentials.Credentials] = None,
    transport: str = "grpc_asyncio",
    client_options: typing.Optional[
        google.api_core.client_options.ClientOptions
    ] = None,
    enable_idempotence: bool = False
)

An AsyncPublisherClient publishes messages similar to Google Pub/Sub, but must be used in an async context. Any publish failures are unlikely to succeed if retried.

Must be used in an async with block or have aenter() awaited before use.
