Subject [GitHub] flink issue #2305: [FLINK-4271] [DataStreamAPI] Enable CoGroupedStreams and ...

Github user StephanEwen commented on the issue:

    We should not change the checker sensitivity. It is very important that it checks for
binary compatibility - that was the promise of Flink 1.0.
    If we want to break compatibility, we can define an exception rule to the checker.
    I think we should explore other options before. We can specify the parallelism between
`window(...)` and `apply(...)` without breaking the compatibility. It would be a bit less
nice, because it is different from how the other functions do it, but it allows us to maintain
the promise of compatibility.
    What do you think about that?
