Daniel Dai commented on HIVE-19251:
-----------------------------------
That's true we'd better provide batch API for potentially large results. That
involves metastore api and rawstore api changes of multiple calls. I'd like to
limit the scope of this ticket as this is mainly a specific bug fix and we can
open new ticket for batch improvement if needed.
> ObjectStore.getNextNotification with LIMIT should use less memory
