---------------------------------
Summary: Poll notification events to invalidate the results cache
Key: HIVE-19154
URL: https://issues.apache.org/jira/browse/HIVE-19154
Project: Hive
Issue Type: Sub-task
Reporter: Jason Dere
Assignee: Jason Dere
Related to the work for HIVE-18609. HIVE-18609 will only invalidate entries in
the cache if that query looked up again, which could potentially leave a lot of
undetected invalid entries in the cache taking up space which could cause other
entries to be evicted. To remove these entries in a more timely fashion, have a
background thread to periodically check the notification events for updates to
the tables used in the results cache.
