Thanks for the update @ldadima . I have fixed up a couple of things in https://github.com/apache/flink/pull/24857 so let me close this PR in favour of that one. Could you take a look at my version?

I checked the MR. I agree with changes about ITCase. In my case I forget about uid, that's why map vertex doesn't work for me in rescale case. Thanks for changes
