Maximilian Michels commented on FLINK-34471:
--------------------------------------------
Thanks! That would be very helpful – I don’t mind at all. I realized point to
point connections might be a bit tricky when the parallelism between tasks
changes from being equal to changing because at runtime we then switch to a
different partitioner. So worst case we could run out of network buffers in
this scenario. I’m curious how you want to solve this. We probably need to add
extra buffers to account for this edge case.
