    Description

      Compactions should trigger stats recalculation for columns which already have sats.

      https://reviews.apache.org/r/25201/

      Major compactions will cause the Compactor to see which columns already have stats and run analyze command for those columns. If compacting a partition then stats for that partition will be computed. If table is not partitioned, then the whole table.
