Piotr Nowojski commented on FLINK-24098:
----------------------------------------
A couple of comments from my side
* UnionList
* General remark/recommendation that the state after `finish()` should be
empty, apart of committing side effects. There should be no buffered records,
as it won't be possible to emit them in anyway
* Remark that recovery with partially finished tasks is very similar to scaling
up, so your operators must support rescaling. And mention for example potential
pitfalls, like using non-keyed ListState
> Document FLIP-147 capabiliites and limitations
