[jira] [Created] (HIVE-20234) Add an option to disable stats computation from Compactor

Eugene Koifman created HIVE-20234:
-------------------------------------

             Summary: Add an option to disable stats computation from Compactor
                 Key: HIVE-20234
                 URL: https://issues.apache.org/jira/browse/HIVE-20234
             Project: Hive
          Issue Type: Improvement
          Components: Transactions
    Affects Versions: 1.0.0
            Reporter: Eugene Koifman


Currently \{{Woker.StatsUpdater}} will run \{{analyze table ... compute statistics for columns ...}} at the end of each Major compaction to update stats on columns that already have stats.

 

It would be useful to add a config option that allows better control over this.  I could have 3 values: don't update col stats, update existing col stats, update all col stats.

Should this have ability to update table level stats?  Is that needed given HIVE-19532?
