Subject [jira] [Created] (FLINK-2802) Watermark triggered operators cannot progress with cyclic flows
Date Fri, 02 Oct 2015 08:24:27 GMT
Gyula Fora created FLINK-2802:
---------------------------------

             Summary: Watermark triggered operators cannot progress with cyclic flows
                 Key: FLINK-2802
                 URL: https://issues.apache.org/jira/browse/FLINK-2802
             Project: Flink
          Issue Type: Bug
          Components: Streaming
            Reporter: Gyula Fora
            Priority: Blocker


The problem is that we can easily create a cyclic watermark (time) dependency in the stream
graph which will result in a deadlock for watermark triggered operators such as  the `WindowOperator`.

A solution to this could be to emit a Long.MAX_VALUE watermark from the iteration sources.
