Subject [GitHub] flink pull request: [streaming] Allow force-enabling checkpoints f...

Github user aljoscha commented on the pull request:

    I would be against merging this in the current form. What I propose is to analyse the
topology to verify that there are no checkpointed operators inside iterations. Operators before
and after iterations can be checkpointed and we can safely allow the user to enable checkpointing.
    If we have the code to analyse which operators are inside iterations we could also disallow
windows inside iterations. I think windows inside iterations don't make sense since elements
in different "iterations" would end up in the same window. Maybe I'm wrong here though, then
please correct me. :smile:
