Pritesh Maker updated DRILL-6754:
---------------------------------
Description:
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.
