Snapshot(mapping=None, *, ignore_unknown_fields=False, **kwargs)

A snapshot resource. 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.

Attributes
Name	Description
name	str The name of the snapshot.
topic	str The name of the topic from which this snapshot is retaining messages.
expire_time	.timestamp.Timestamp The snapshot is guaranteed to exist up until this time. A newly-created snapshot expires no later than 7 days from the time of its creation. Its exact lifetime is determined at creation by the existing backlog in the source subscription. Specifically, the lifetime of the snapshot is 7 days - (age of oldest unacked message in the subscription). For example, consider a subscription whose oldest unacked message is 3 days old. If a snapshot is created from this subscription, the snapshot -- which will always capture this 3-day-old backlog as long as the snapshot exists -- will expire in 4 days. The service will refuse to create a snapshot that would expire in less than 1 hour after creation.
labels	Sequence[.pubsub.Snapshot.LabelsEntry] See [Creating and managing labels] (https://cloud.google.com/pubsub/docs/labels).
