Description
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.
