Kostas Kloudas commented on FLINK-5853:
---------------------------------------

Hi [~dawidwys]! Isn't the same functionality offered also by the recently added {{IterativeConditions}}? If this is the case, then I would suggest to move the discussion to the issue https://issues.apache.org/jira/browse/FLINK-6420 where the discussion is on the more general API constructs we offer.

What do you think?
