-----------------------------------

             Summary: [C++] Add unit tests and documentation for swiss-join 
                 Key: ARROW-17022
                 URL: https://issues.apache.org/jira/browse/ARROW-17022
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++
            Reporter: Weston Pace
            Assignee: Weston Pace


The swiss join utilities being added as part of ARROW-14182 are not adequately unit tested at the moment.  They have fairly decent coverage from end-to-end random hash join testing.  However, a set of basic unit tests will help future maintenance by demonstrating basic usage and allowing for more targeted fixes when a refactor breaks something.  I'm doing some of this work as I review ARROW-14182 anyways so that I can better understand it.  Rather than complicate the review I will open this as a separate follow-up PR.
