Events that are of no interest to any started EPL statement are simply dropped. There is no internal queue they are retained in. There is also no concept of time-to-live for unmatched events. Your application can use the UnmatchedEventListener interface to catch an event that is dropped because no EPL statement needs to see it. Your application would need to retain and retry such unmatched events to achieve a time-to-live for unmatched events.
