Overview
This Snap is used to acknowledge the pubsub messages with ack ids read by a Pubsub Subscriber used in the upstream Snap. This snap can also be used with out the subscriber snap, by passing the ackIds directly from inputstream.
Note:
This snap supports acknowledging for a single ackId or for a batch of ackIds.
For single message , the ackId can be given directly in the property “Acknowledgment Id”.
For batch messages , the ackIds can be given in a json and mapped to the property “Acknowledgment Id”.
If batchsize > 1, and an acknowledgement in a batch fails means that batch will fail completely. The ackIds belongs to the failed batch will be sent to the error view.
