[jira] [Created] (ARROW-13295) [C++] Implement hash_aggregate mean/stdev/variance kernels

David Li created ARROW-13295:
--------------------------------

             Summary: [C++] Implement hash_aggregate mean/stdev/variance kernels
                 Key: ARROW-13295
                 URL: https://issues.apache.org/jira/browse/ARROW-13295
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++
            Reporter: David Li
            Assignee: David Li


We have scalar aggregate kernels for these already that can serve as the basis for a hash aggregate implementation.

Depends on ARROW-12759 as that refactors  how hash aggregate kernels are implemented.
