Github user gyfora commented on the pull request: https://github.com/apache/flink/pull/802#issuecomment-120276079 I am currently preparing a new PR with a rework of how the iterations are constructed in the StreamGraph it will be ready today. It will solve many issues that we currently have and will make the iterations much more robust. I am also adding a bunch of new tests. I think this is still a good addition because some of my tests will depend on the maxWaitTime. I propose to add your changes afterwards. I volunteer to port your commits to my changes :)
