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

             Summary: Add a field to SV2 to indicate if the SV2 reorders the Record Batch
                 Key: DRILL-6754
                 URL: https://issues.apache.org/jira/browse/DRILL-6754
             Project: Apache Drill
          Issue Type: Improvement
         Environment: The optimization in DRILL-6687 is not correct if an SV2 is used to re-order rows in the record batch. Currently, this is not a problem because none of the reordering operators (SORT, TOPN) use an SV2. SORT has code for SV2 but it is disabled. 

Adding a field to SV2 to indicate if the SV2 reorders the Record Batch would allow the safe application of the DRILL-6687 optimization.
