Class LocalSnapshotStore

  • All Implemented Interfaces:
    akka.actor.Actor, akka.actor.ActorLogging, akka.persistence.snapshot.SnapshotStore
    public class LocalSnapshotStore
extends akka.persistence.snapshot.japi.SnapshotStore
    Akka SnapshotStore implementation backed by the local file system. This class was patterned after akka's LocalSnapshotStore class and exists because akka's version serializes to a byte[] before persisting to the file which will fail if the data reaches or exceeds Integer.MAX_VALUE in size. This class avoids that issue by serializing the data directly to the file.
