[jira] [Created] (HIVE-14667) Eliminate OrcRecordUpdate.OPERATION

Eugene Koifman created HIVE-14667:
-------------------------------------

             Summary: Eliminate OrcRecordUpdate.OPERATION
                 Key: HIVE-14667
                 URL: https://issues.apache.org/jira/browse/HIVE-14667
             Project: Hive
          Issue Type: Bug
          Components: Transactions
    Affects Versions: 2.2.0
            Reporter: Eugene Koifman


With HIVE-14035, for acid tables with 'transactional_properties'='default', it should be possible to eliminate the type of event property (at least on disk) since each type of delta file contains exactly 1 type events.

Also, for insert deltas as well as base files, all rows have originalTxnId=currentTxnId.

Not sure if it's worth the effort given RLE in ORC
