Dandandan opened a new issue #636:
URL: https://github.com/apache/arrow-rs/issues/636


   **Is your feature request related to a problem or challenge? Please describe what you are trying to do.**
   Some optimization possible in the kernel seems to avoid materializing (start, end) and pre-building the filter when there is only a single input array.
   
   **Describe the solution you'd like**
   Don't pre-build the filter but use the normal `filter` for a single array instead
   
   **Describe alternatives you've considered**
   
   **Additional context**
   Same as https://github.com/jorgecarleitao/arrow2/pull/235
