Supports bulk acknowledging or un-acknowledging of messages to given snapshot or point of time based on the seekTarget provided.

Seeking to a time marks every message received by Pub/Sub before the time as acknowledged, and all messages received after the time as unacknowledged. That means that you can replay and reprocess previously acknowledged messages when seeking to a time in past or purge messages by seeking to a time in the future. NOTE: If you seek to a timestamp using a subscription with a filter, the Pub/Sub service only redelivers the messages that match the filter

The snapshot feature allows you to capture the message acknowledgment state of a subscription. Once a snapshot is created, it retains:

• All messages that were unacknowledged in the source subscription at the time of the snapshot's creation.
• Any messages published to the topic thereafter.

You can replay these unacknowledged messages by using a snapshot to seek to any of the topic's subscriptions. NOTE: If you seek to a snapshot using a subscription with a filter, the Pub/Sub service only redelivers the messages in the snapshot that match the filter of the subscription making the seek request.

Parameters:

config - configuration

connection - connection

subscriptionIdentifier - Identifier of the subscription containing subscriptionName and projectId

seekTarget - Target of the seek operation either a snapshot or specific time
