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

             Summary: Rewrite MergeJoinBatch using record batch iterator.
                 Key: DRILL-3793
                 URL: https://issues.apache.org/jira/browse/DRILL-3793
             Project: Apache Drill
          Issue Type: Improvement
          Components: Execution - Relational Operators
            Reporter: amit hadke
            Assignee: amit hadke


Current implementation of merge join operator is convoluted as it has to handle duplicates
between record batches. MergeJoin rewrite should use record batch iterator which hides the
complexity of managing multiple record batches and iterating through them.
