> 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.
