-------------------------------------

             Summary: Enable Delete Event filtering in VectorizedOrcAcidRowBatchReader
                 Key: HIVE-20738
                 URL: https://issues.apache.org/jira/browse/HIVE-20738
             Project: Hive
          Issue Type: Improvement
          Components: Transactions
    Affects Versions: 3.0.0
            Reporter: Eugene Koifman
            Assignee: Eugene Koifman


Currently DeleteEventRegistry loads all delete events which can take time and use a lot of memory.  Should minimize the number of deletes loaded based on the insert events included in the Split.
This is an umbrella jira for several tasks that make up the work.  See individual tasks for details.
