> -----------------------------------------
>
>                 Key: ARROW-10964
>                 URL: https://issues.apache.org/jira/browse/ARROW-10964
>             Project: Apache Arrow
>          Issue Type: Improvement
>          Components: Rust - DataFusion
>            Reporter: Andy Grove
>            Priority: Major
>
> 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.
