Class LocalSnapshotStore

java.lang.Object

akka.persistence.snapshot.japi.SnapshotStore

org.opendaylight.controller.cluster.persistence.LocalSnapshotStore

All Implemented Interfaces:

Actor, ActorLogging, SnapshotStore

public class LocalSnapshotStore
extends 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.
