The query with "SELECT *" with "ORDER BY" clause and `planner.slice_tâ¦
â¦arget`=1 doesn't preserve column order
Issue: Columns ordering doesn't preserve for the star query with sorting
when this is planned into multiple fragments.
Solution: The commit for DRILL-847 is oudated. There is no need to
canonicalize the batch or container since RecordBatchLoader swallows the
"schema change" for now if two batches have different column ordering.
