[GitHub] [arrow] felipecrv opened a new issue, #35058: [C++] Fix handling of logical nulls by compute kernels processing run-end encoded arrays or arrays of unions

["felipecrv (via GitHub)" <gi...@apache.org>]

felipecrv opened a new issue, #35058:
URL: https://github.com/apache/arrow/issues/35058

   ### Describe the bug, including details regarding any error messages, version, and platform.
   
   Since #34361 and the introduction of special validity checks in #34408, we are aware that parts of the codebase handle nulls the wrong way when the input is a run-end encoded array (NEW) or an union array.
   
   This issue aims to be a list of compute kernels that have to be changed regarding nulls in these special array types by using specialized ways of determining a valid is a logical null instead of relying on validity bitmaps that are absent in these types of arrays:
   
   - [ ] `is_null` #34315
   - [ ] `count`
   - [ ] ...
   
   ### Component(s)
   
   C++
