.Query events for a specific

.You can retrieve a subset of all events by specifying
fromSequenceNr

or use0L
andLong.MaxValue
respectively to retrieve all events.The returned event stream should be ordered by sequence number.
The stream is not completed when it reaches the end of the currently stored events, but it continues to push new events when new events are persisted. Corresponding query that is completed when it reaches the end of the currently stored events is provided by CurrentEventsByPersistenceIdQuery#currentEventsByPersistenceId.
