**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** The `partition_validity` method looks like it could be more efficient, the current code does not pre-allocate the vectors with the correct capacity based on the known null counts. It also calls `Array::is_valid` via dynamic dispatch, instead of first getting the `NullBuffer` and calling `NullBuffer::is_valid`, which could be inlined. **Describe the solution you'd like** Try to improve it and run the `sort_kernels` microbenchmark. **Describe alternatives you've considered** <!-- A clear and concise description of any alternative solutions or features you've considered. --> **Additional context** <!-- Add any other context or screenshots about the feature request here. --> -- This is an automated message from the Apache Git Service.
