class SharedLeveldbStore extends LeveldbStore
A LevelDB store that can be shared by multiple actor systems. The shared store must be
set for each actor system that uses the store via SharedLeveldbJournal.setStore
. The
shared LevelDB store is for testing only.

- def asyncReplayMessages(persistenceId: String, fromSequenceNr: Long, toSequenceNr: Long, max: Long)(replayCallback: (PersistentRepr) => Unit): Future[Unit]
Plugin API: asynchronously replays persistent messages.
Plugin API: asynchronously replays persistent messages. Implementations replay a message by calling
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'sdeleted
method must returntrue
.The
toSequenceNr
is the lowest of what was returned by #asyncReadHighestSequenceNr and what the user specified as recovery akka.persistence.Recovery parameter. This does imply that this call is always preceded by reading the highest sequence number for the givenpersistenceId
.This call is NOT protected with a circuit-breaker because it may take long time to replay all events. The plugin implementation itself must protect against an unresponsive backend store and make sure that the returned Future is completed with success or failure within reasonable time. It is not allowed to ignore completing the future.
- 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.
