Arvid Heise commented on FLINK-25920:
-------------------------------------
Hi folks, I tried to repro the issue to no avail. Can someone please share
their logs (ideally trace, at least debug), so I can proceed?
If you can't share them publicly, I can confidentially handle them (find me on
Flink slack or mail me [email protected]). I can sign NDAs etc.
My only hypothesis is that this is connected to rescaling but I can't find the
exact pattern since the code in theory accounts for upscaling and downscaling.
