I do not plan to merge it like this, since it duplicating a lot of code from arrow, but I'm doing it as a POC ## Which issue does this PR close? N/A ## Rationale for this change I wanna see if there is a perf benefit of avoiding concat and sort/sort_to_indecies + take and replacing it with modified sort to indices + interleave ## What changes are included in this PR? copied arrow sort and modified it to work on slice of input array and make it return `Vec<(array_index, index_in_array)>` for `lexort_to_indices` or return Vec<Array> for `sort` ## What is the testing strategy for this PR? Unit tests and existing tests ## Are there any user-facing changes? No -- This is an automated message from the Apache Git Service.
