[GitHub] [arrow-rs] bjchambers opened a new issue #650: Comparison kernel documentation is incorrect

bjchambers opened a new issue #650:
URL: https://github.com/apache/arrow-rs/issues/650


   **Describe the bug**
   
   The documentation on the comparison kernels is incorrect. They use `combine_option_bitmap` to combine the null bitmaps, meaning the result is `null` if either of the inputs is `null`. This corresponds to the SQL treatment of `null` as unknown. This seems to be supported by the tests.
   
   The rustdoc comments however indicate that `Null values are less than non-null values.`.
   
   **To Reproduce**
   Run the comparison tests.
   
   **Expected behavior**
   Documentation matches the behavior.
   
   **Additional context**
