Steve Yeom commented on HIVE-18395: ----------------------------------- Another viewpoint/reason why not using stats on a ACID/MM table is that a reader/select statement can not have a snapshot isolation regarding "actual data" and "stats on the Metastore". Since update on the data and the stats on the Metastore is not single transaction based. > Using stats for aggregates on Acid/MM is off even with > "hive.compute.query.using.stats" is true. > ------------------------------------------------------------------------------------------------ > > Key: HIVE-18395 > URL: https://issues.apache.org/jira/browse/HIVE-18395 > Project: Hive > Issue Type: Bug > Affects Versions: 3.0.0 > Reporter: Steve Yeom > Priority: Minor > -- This message was sent by Atlassian JIRA (v6.4.14#64029)
