-----------------------------------
Hey [~thai.bui], sorry didn't get around to working on this one.
How about going with the approach outlined
[here|https://issues.apache.org/jira/browse/HIVE-20250?focusedCommentId=16565715&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-16565715].
That would enable your case with the timeout approach. Feel free to try to
take up, or I will eventually get around to it when I get a chance.
Regarding the ability to receive notifications to invalidate the cache, there
is also HIVE-19154, where HS2 is able to listen on metastore notification
events to invalidate result cache entries. If you are able to generate a basic
ALTER TABLE or ALTER PARTITION statement on the table which results in the
metastore generating the notification event, this could suit your purposes.
