In longer term, we may introduce a common > representation for the column statistics stored by different engines. > For this issue, we will add a new column 'engine' to TAB_COL_STATS HMS table > (unpartitioned tables) and to PART_COL_STATS HMS table (partitioned tables). > This will prevent conflicts at the column level stats. -- This message was sent by Atlassian JIRA (v7.6.14#76016)
