[jira] [Created] (ARROW-13764) [C++] Implement ScalarAggregateOptions for count_distinct (grouped)

Nic Crane created ARROW-13764:
---------------------------------

             Summary: [C++] Implement ScalarAggregateOptions for count_distinct (grouped) 
                 Key: ARROW-13764
                 URL: https://issues.apache.org/jira/browse/ARROW-13764
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++
            Reporter: Nic Crane


I'm writing the R bindings for the grouped {{count_distinct}} kernel, but the current implementation counts nulls as their own group.  To match the R behaviour,  I need to be able to specify whether or not to remove NA/NULL values.

Please could we have ScalarAggregateOptions implemented for {{count_distinct}}?
