[jira] [Created] (ARROW-10964) [Rust] [DataFusion] Optimize nested joins

Andy Grove created ARROW-10964:
----------------------------------

             Summary: [Rust] [DataFusion] Optimize nested joins
                 Key: ARROW-10964
                 URL: https://issues.apache.org/jira/browse/ARROW-10964
             Project: Apache Arrow
          Issue Type: Improvement
          Components: Rust - DataFusion
            Reporter: Andy Grove


Once [https://github.com/apache/arrow/pull/8961] is merged, we have an optimization for a JOIN that operates on two tables.

The next step is to extend this optimization to work with nested joins, and this is not trivial. See discussion in [https://github.com/apache/arrow/pull/8961] for context.
