Value Members

  1. val disabled: RetentionCriteria

    Snapshots are not saved and deleted automatically, events are not deleted.

  2. def snapshotEvery(numberOfEvents: Int): SnapshotCountRetentionCriteria

    Save snapshots automatically every numberOfEvents.

    Save snapshots automatically every numberOfEvents.

    Use SnapshotCountRetentionCriteria.withDeleteEventsOnSnapshot to delete old events. Events are not deleted by default.

    If multiple events are persisted with a single Effect, the snapshot will happen after all of the events are persisted rather than precisely every numberOfEvents.

  3. def snapshotEvery(numberOfEvents: Int, keepNSnapshots: Int): SnapshotCountRetentionCriteria

    Save snapshots automatically every numberOfEvents.

    Save snapshots automatically every numberOfEvents. Snapshots that have sequence number less than the sequence number of the saved snapshot minus keepNSnapshots * numberOfEvents are automatically deleted.

    Use SnapshotCountRetentionCriteria.withDeleteEventsOnSnapshot to delete old events. Events are not deleted by default.

    If multiple events are persisted with a single Effect, the snapshot will happen after all of the events are persisted rather than precisely every numberOfEvents.
