Hi Moiz, You are on Flink 1.2 or 1.3? In Flink 1.2 (latest stable) there are no known issues, so this will work correctly. Keep in mind that without any conditions (where-clauses), you will only get all possible 2-tuples of incoming elements, which could also be done with a simple process function I would say.
In Flink 1.3 (unreleased) there is this issue: https://issues.apache.org/jira/browse/FLINK-6445 <https://issues.apache.org/jira/browse/FLINK-6445> Thanks, Kostas > On May 4, 2017, at 1:45 PM, Moiz S Jinia <moiz.ji...@gmail.com> wrote: > > Does Flink (with a persistent State backend such as RocksDB) work well with > long running Patterns of this type?
