Hello Fabian, So could I assume the followings?
1. Neither PURGE nor clear() removes the States (so the States must be explicitly cleared by the user). 2. When an event for a window arrives after PURGE has been called, it is still be processed, and is treated as the first event of that window. And one related question: for keyed streams, if I know that some keys would never have new events anymore, should/could I remove those streams corresponding to those keys so that I can save some memory allocated to the metadata? Thanks and best regards, Averell -- Sent from: http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/
