final class NoSnapshotStore extends SnapshotStore

Used as default snapshot-store in case no other store was configured.

If a akka.persistence.PersistentActor calls the akka.persistence.PersistentActor#saveSnapshot method, and at the same time does not configure a specific snapshot-store to be used *and* no default snapshot-store is available, then the NoSnapshotStore will be used to signal a snapshot store failure.

    If the future Option is None then all events will be replayed, i.e. there was no snapshot. If snapshot could not be loaded the Future should be completed with failure. That is important because events may have been deleted and just replaying the events might not result in a valid state.
