Method Detail

disabled

public RetentionCriteria disabled()

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

snapshotEvery

public SnapshotCountRetentionCriteria snapshotEvery(int numberOfEvents,
                                                    int keepNSnapshots)

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.

snapshotEvery

public SnapshotCountRetentionCriteria snapshotEvery(int 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.
