Thomas Weise commented on APEXCORE-595:
---------------------------------------
I don't think there is anything that needs to be done regarding bufferserver.
The master should only send a valid committed windowId to the containers.
> Master incorrectly updates committedWindowId when all partitions are
> terminated.
