      Description

      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
