Eventsourced | CEP |

The Eventsourced library adds scalable actor state persistence and at-least-once message delivery guarantees to Akka. With Eventsourced, stateful actors persist received messages by appending them to a log (journal)

project received messages to derive current stateusually hold current state in memory (memory image)recover current (or past) state by replaying received messages (during normal application start or after crashes)never persist current state directly (except optional state snapshots for recovery time optimization)
