Alexander Kolbasov commented on HIVE-19251:
-------------------------------------------
I think this patch is fine, but in the long term we should always limit the
number of returned events even if -1 is specified (or some big number)
Consumers can always ask for more.
> ObjectStore.getNextNotification with LIMIT should use less memory
