    Snapshots are not saved and deleted automatically, events are not deleted.
  - snapshotEvery
```
public static 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

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