[jira] [Commented] (HIVE-18513) Query results caching

    [ https://issues.apache.org/jira/browse/HIVE-18513?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16484084#comment-16484084 ] 

Thai Bui commented on HIVE-18513:
---------------------------------

Hi [~jdere], this new feature is awesome. I'm glad we are implementing it in the next generation of Hive. I'm currently using Hive 3.1.0-SNAPSHOT but haven't seen this working yet, perhaps there's a couple of configurations parameters that I am missing. Also, does it work with EXTERNAL tables or just managed / ACID tables?

> Add a query results cache that can save the results of an executed Hive query for reuse on subsequent queries. This may be useful in cases where the same query is issued many times, since Hive can return back the results of a cached query rather than having to execute the full query on the cluster.
