Dawid Wysakowicz commented on FLINK-24489:
------------------------------------------
Moreover I am not sure how severe the problem is. I think it's not easy to
deplete the memory. The cache is valid just for the time of processing a single
record. One would need rather a really long pattern.
If it is a problem, maybe a better idea would be to add a flag to disable
caching whatsoever.
