[jira] [Created] (ARROW-16145) [C++] Vector kernels should implement or reject null_handling = INTERSECTION

David Li created ARROW-16145:
--------------------------------

             Summary: [C++] Vector kernels should implement or reject null_handling = INTERSECTION
                 Key: ARROW-16145
                 URL: https://issues.apache.org/jira/browse/ARROW-16145
             Project: Apache Arrow
          Issue Type: Bug
          Components: C++
            Reporter: David Li


As discovered in ARROW-13530, right now the framework will let you register a vector kernel with null_handling = INTERSECTION, but doesn't actually implement that (it'll preallocate but won't compute the result). We should either implement it, or decide it makes no sense and explicitly reject registering kernels with this null handling mode.
