   Linking https://github.com/apache/arrow-datafusion/issues/416 and https://github.com/apache/arrow-datafusion/issues/1572 as at least historically `MutableArrayData` was one of the bottlenecks in `SortPreservingMerge`. In particular the code used to reconstruct a record batch https://github.com/apache/arrow-datafusion/blob/master/datafusion/src/physical_plan/sorts/sort_preserving_merge.rs#L452
