Subject [jira] [Updated] (HIVE-15069) Optimize MetaStoreDirectSql:: aggrColStatsForPartitions during query compilation
Date Wed, 26 Oct 2016 07:39:58 GMT

     [ https://issues.apache.org/jira/browse/HIVE-15069?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Rajesh Balamohan updated HIVE-15069:
------------------------------------
    Attachment: HIVE-15069.1.patch

With patch, compilation time comes down to "2.62" seconds vs 4-5 seconds earlier (1 node LLAP
in my environment).  Also tried with Q-55 in single node LLAP. Without patch, it took ~1.3-1.5
seconds for query compilation. With the patch it takes 0.80 seconds.
