Jason Dere commented on HIVE-18513: ----------------------------------- Created a simple patch for this at HIVE-20250, but had some pushback from [~hagleitn] over concern that customers would misunderstand some of the settings. Will leave more comments at HIVE-20250. Will try to add some docs when I get a chance. There aren't any memory management settings (the results are kept in HDFS in the results cache directory), but are settings related to size of the results kept by a single Hive instance (hive.query.results.cache.max.size, hive.query.results.cache.max.entry.size). > 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)
