Jason Dere created HIVE-19154: --------------------------------- 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. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
