             Summary: Update stats of table/partition after minor compaction using noscan operation
                 Key: HIVE-26788
                 URL: https://issues.apache.org/jira/browse/HIVE-26788
             Project: Hive
          Issue Type: Improvement
            Reporter: Sourabh Badhya
            Assignee: Sourabh Badhya


Currently, statistics are not updated for minor compaction since minor compaction performs little updates on the statistics (such as number of files in table/partition & total size of the table/partition). It is better to utilize NOSCAN operation  for minor compaction since NOSCAN operations performs faster update of statistics and updates the relevant fields such as number of files & total sizes of the table/partitions.
