[jira] [Created] (HIVE-23559) Optimise Hive::moveAcidFiles for cloud storage

Rajesh Balamohan created HIVE-23559:
---------------------------------------

             Summary: Optimise Hive::moveAcidFiles for cloud storage
                 Key: HIVE-23559
                 URL: https://issues.apache.org/jira/browse/HIVE-23559
             Project: Hive
          Issue Type: Bug
            Reporter: Rajesh Balamohan


[https://github.com/apache/hive/blob/master/ql/src/java/org/apache/hadoop/hive/ql/metadata/Hive.java#L4752]

It ends up transferring DELTA, DELETE_DELTA, BASE prefixes sequentially from staging to final location.

This causes delays even with simple updates statements, which updates smaller number of records in cloud storage.
