Wei Zheng updated HIVE-13354: ----------------------------- Attachment: (was: HIVE-13354.2.patch) > Add ability to specify Compaction options per table and per request > ------------------------------------------------------------------- > > Key: HIVE-13354 > URL: https://issues.apache.org/jira/browse/HIVE-13354 > Project: Hive > Issue Type: Improvement > Affects Versions: 1.3.0, 2.0.0 > Reporter: Eugene Koifman > Assignee: Wei Zheng > Labels: TODOC2.1 > Attachments: HIVE-13354.1.patch, > HIVE-13354.1.withoutSchemaChange.patch, HIVE-13354.2.patch > > > Currently the are a few options that determine when automatic compaction is > triggered. They are specified once for the warehouse. > This doesn't make sense - some table may be more important and need to be > compacted more often. > We should allow specifying these on per table basis. > Also, compaction is an MR job launched from within the metastore. There is > currently no way to control job parameters (like memory, for example) except > to specify it in hive-site.xml for metastore which means they are site wide. > Should add a way to specify these per table (perhaps even per compaction if > launched via ALTER TABLE) -- This message was sent by Atlassian JIRA (v6.3.4#6332)
