Class AsyncSubscriberClient (1.11.0) 

AsyncSubscriberClient(

    nack_handler: typing.Optional[
        google.cloud.pubsublite.cloudpubsub.nack_handler.NackHandler
    ] = None,
    reassignment_handler: typing.Optional[

    client_options: typing.Optional[google.api_core.client_options.ClientOptions] = None
)

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

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

subscribe

subscribe(
    subscription: typing.Union[
        google.cloud.pubsublite.types.paths.SubscriptionPath, str
    ],
    per_partition_flow_control_settings: google.cloud.pubsublite.types.flow_control_settings.FlowControlSettings,
    fixed_partitions: typing.Optional[
        typing.Set[google.cloud.pubsublite.types.partition.Partition]
    ] = None,
) -> typing.AsyncIterator[google.cloud.pubsub_v1.subscriber.message.Message]

Read messages from a subscription.

Parameters
Name Description
subscription typing.Union[google.cloud.pubsublite.types.paths.SubscriptionPath, str]

The subscription to subscribe to.
per_partition_flow_control_settings FlowControlSettings

The flow control settings for each partition subscribed to. Note that these settings apply to each partition individually, not in aggregate.
fixed_partitions typing.Optional[typing.Set[google.cloud.pubsublite.types.partition.Partition]]

A fixed set of partitions to subscribe to. If not present, will instead use auto-assignment.
