-------------------------------
Resolution: Invalid
> [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
> 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.
