[jira] [Created] (HIVE-21953) Enable CLUSTERED ON/DISTRIBUTED ON+SORTED ON in incremental rebuild of materialized views

Jesus Camacho Rodriguez created HIVE-21953:
----------------------------------------------

             Summary: Enable CLUSTERED ON/DISTRIBUTED ON+SORTED ON in incremental rebuild of materialized views
                 Key: HIVE-21953
                 URL: https://issues.apache.org/jira/browse/HIVE-21953
             Project: Hive
          Issue Type: Bug
          Components: Materialized views
            Reporter: Jesus Camacho Rodriguez
            Assignee: Jesus Camacho Rodriguez


Follow-up of HIVE-18842. For insert and insert branch in merge, we can introduce a RS to enforce these properties, as we do when we create the materialized view or execute a full rebuild. This will make delta files created for the insert to obey the same organization. If the increments are large enough, this may improve query execution performance.
