[GitHub] [arrow] a-reich opened a new issue, #37087: Missing kernels for ordering with struct types

a-reich opened a new issue, #37087:
URL: https://github.com/apache/arrow/issues/37087

   ### Describe the enhancement requested
   
   Currently, using order-related pyarrow compute functions like `min_max`, `array_sort_indices` on a StructArray raises due to missing kernel.
   Since a struct type is an ordered sequence of values with a fixed number of fields, whenever all the field types are orderable there is a natural way to order struct values lexicographically. I think this would be useful functionality, and is not easy for users to do themselves.
   
   ### Component(s)
   
   Python

   The issue is still valid since this functionality remains missing.
   
   FWIW, I think the implementation might need https://github.com/apache/arrow/issues/17211, but PRs for that have gone through a couple versions and waited in limbo over the years. (Current is #45001)
