replayCallback
. The returned future must be completed
when all messages (matching the sequence number bounds) have been replayed.
The future must be completed with a failure if any of the persistent messages
could not be replayed.
The replayCallback
must also be called with messages that have been marked
as deleted. In this case a replayed message's deleted
method must return
true
.
The channel ids of delivery confirmations that are available for a replayed
message must be contained in that message's confirms
sequence.
persistenceId
- persistent actor id.fromSequenceNr
- sequence number where replay should start (inclusive).toSequenceNr
- sequence number where replay should end (inclusive).max
- maximum number of messages to be replayed.replayCallback
- called to replay a single message. Can be called from any
thread.

.
persistenceId
- persistent actor id.fromSequenceNr
- hint where to start searching for the highest sequence
number.
