Yuepeng Pan commented on FLINK-24489:
-------------------------------------
We cannot control the size of time interval in users' production environment.
If we set those thresholds for the cache containers, it could reduce the
probability of such problems. This is one of the reasons why the cache has
threshold number of entry or memory capacity.
> The size of entryCache & eventsBufferCache in the SharedBuffer should be
> defined with a threshold to limit the number of the elements in the cache
