> ----------------------------------------------------------------------------

> Project: Apache Arrow
> Issue Type: Improvement
> Components: Rust - DataFusion
> Reporter: Andy Grove

> https://issues.apache.org/jira/browse/ARROW-10781 to build an optimizer rule
> to determine the smaller side of a join and use that as the build/hash side.
