# Which issue does this PR close? Closes #5230 . # Rationale for this change Modifying SortExec to use arrow row format should increase performance when sorting by multiple columns. # What changes are included in this PR? This is a draft PR and currently only the first iteration is implemented: > A first iteration could simply modify sort_batch to use the row format for multi-column sorts, as demonstrated [here](https://docs.rs/arrow-row/latest/arrow_row/#lexsort), falling back to sort_to_indices if only a single column. # Are these changes tested? Existing unit tests for SortExec cover this. # Are there any user-facing changes? no -- This is an automated message from the Apache Git Service.
