Matthias Pohl commented on FLINK-27133:
---------------------------------------
Thanks for clarification. Hence, the jump around March 10, 2022 is not
reasonable based on the commits. Same goes for the drop which is part of that
issue based on the experiments I did. The test itself is quite flaky.
FLINK-27165 is created as a follow-up to fix (or at least understand) the
flakiness. I'm gonna close this issue as not-reproducible because current state
is back to the levels we had before March 10, 2022.
