Class Recovery

  • All Implemented Interfaces:, scala.Equals, scala.Product

    public final class Recovery
    extends java.lang.Object
    implements scala.Product,
    Recovery mode configuration object to be returned in PersistenceRecovery.recovery().

    By default recovers from latest snapshot replays through to the last available event (last sequenceId).

    Recovery will start from a snapshot if the persistent actor has previously saved one or more snapshots and at least one of these snapshots matches the specified fromSnapshot criteria. Otherwise, recovery will start from scratch by replaying all stored events.

    If recovery starts from a snapshot, the persistent actor is offered that snapshot with a SnapshotOffer message, followed by replayed messages, if any, that are younger than the snapshot, up to the specified upper sequence number bound (toSequenceNr).

    param: fromSnapshot criteria for selecting a saved snapshot from which recovery should start. Default is latest (= youngest) snapshot. param: toSequenceNr upper sequence number bound (inclusive) for recovery. Default is no upper bound. param: replayMax maximum number of messages to replay. Default is no limit.

        public static Recovery none()
        Convenience method for skipping recovery in PersistentActor.

        It will still retrieve previously highest sequence number so that new events are persisted with higher sequence numbers rather than starting from 1 and assuming that there are no previous event with that sequence number.
