Jason Dere commented on HIVE-18513: ----------------------------------- It is certainly doable, would need changes in HiveRelOpMaterializationValidator (which checks that the expression involves temporary or external tables, or non-deterministic functions, all of which currently disqualify the results from being cached). I might be able to do the patch sometime next week if you don't mind waiting. > Query results caching > --------------------- > > Key: HIVE-18513 > URL: https://issues.apache.org/jira/browse/HIVE-18513 > Project: Hive > Issue Type: Bug > Components: Query Planning > Reporter: Jason Dere > Assignee: Jason Dere > Priority: Major > Fix For: 3.0.0 > > Attachments: HIVE-18513.1.patch, HIVE-18513.2.patch, > HIVE-18513.3.patch, HIVE-18513.4.patch, HIVE-18513.5.patch, HIVE-18513.6.patch > > > 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. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
