Hello Till <trohrm...@apache.org>, >From your prompt reply:
'... the CountTrigger *always* works together with the CountEvictor which will make sure that only .. ' - that explains it. Thanks. I missed it. A related question I have is this: Between the PURGE facility of Trigger and REMOVAL facility of Evictor, is there really a difference? Who *uses* the value that an Evictor.evict(Iterable<StreamRecord<Object>> elements, int size, W window) { ..... } returns? A trigger doesn't seem to do it. -- Nirmalya -- Software Technologist http://www.linkedin.com/in/nirmalyasengupta "If you have built castles in the air, your work need not be lost.
