public virtual Task<Empty> DeleteTopic(DeleteTopicRequest request, ServerCallContext context)
Deletes the topic with the given name. Returns NOT_FOUND if the topic
does not exist. After a topic is deleted, a new topic may be created with
the same name; this is an entirely new topic with none of the old
configuration or subscriptions. Existing subscriptions to this topic are
not deleted, but their topic field is set to _deleted-topic_.
public virtual Task<DetachSubscriptionResponse> DetachSubscription(DetachSubscriptionRequest request, ServerCallContext context)
Detaches a subscription from this topic. All messages retained in the
subscription are dropped. Subsequent Pull and StreamingPull requests
will return FAILED_PRECONDITION. If the subscription is a push
subscription, pushes to the endpoint will stop.
public virtual Task<ListTopicSnapshotsResponse> ListTopicSnapshots(ListTopicSnapshotsRequest request, ServerCallContext context)
Lists the names of the snapshots on this topic. Snapshots are used in
Seek 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.
