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

> Experience OOM when Hive metastore try to retrieve huge amount of 
> notification logs even there's limit clause. Hive shall only retrieve 
> necessary rows.
