[jira] [Created] (ARROW-13877) [C++] Added support for fixed sized list to compute functions that process lists

Weston Pace created ARROW-13877:
-----------------------------------

             Summary: [C++] Added support for fixed sized list to compute functions that process lists
                 Key: ARROW-13877
                 URL: https://issues.apache.org/jira/browse/ARROW-13877
             Project: Apache Arrow
          Issue Type: Bug
          Components: C++
            Reporter: Weston Pace


The following functions do not support fixed size list (and should):

 - list_flatten
 - list_parent_indices (one could argue this doesn't need to be supported since this should be obvious and fixed_size_list doesn't have an indices array)
 - list_value_length (should be easy)

For reference, the following functions do correctly consume fixed_size_list (there may be more, this isn't an exhaustive list):

 - count
 - drop_null
 - is_null
 - is_valid
