[jira] [Created] (ARROW-10727) [Rust] [DataFusion] Add SQL support for NATURAL JOIN

Andy Grove created ARROW-10727:
----------------------------------

             Summary: [Rust] [DataFusion] Add SQL support for NATURAL JOIN
                 Key: ARROW-10727
                 URL: https://issues.apache.org/jira/browse/ARROW-10727
             Project: Apache Arrow
          Issue Type: New Feature
          Components: Rust - DataFusion
            Reporter: Andy Grove


(We cannot do this until we have basic SQL JOIN working)

A *NATURAL JOIN* is a *JOIN* operation that creates an implicit *join* clause for you based on the common columns in the two tables being *joined*. Common columns are columns that have the same name in both tables. A *NATURAL JOIN* can be an INNER *join*, a LEFT OUTER *join*, or a RIGHT OUTER *join*. The default is INNER *join*.
