[jira] [Created] (ARROW-13931) [C++] Coalesce kernel missing support for list/struct types

Weston Pace created ARROW-13931:
-----------------------------------

             Summary: [C++] Coalesce kernel missing support for list/struct types
                 Key: ARROW-13931
                 URL: https://issues.apache.org/jira/browse/ARROW-13931
             Project: Apache Arrow
          Issue Type: Bug
          Components: C++
            Reporter: Weston Pace


List and struct types aren't sortable and one could debate whether they should be equatable or not but coalesce should only require nullable and all data types should be nullable.  So I would expect coalesce to work on any data type.  At the moment it does not support list/struct data types even when all arguments are the same type.
