Todd Farmer updated ARROW-16485:
--------------------------------
Component/s: C++
> [C++] Improving Substrait-Join Integration
> ------------------------------------------
>
> Key: ARROW-16485
> URL: https://issues.apache.org/jira/browse/ARROW-16485
> Project: Apache Arrow
> Issue Type: Improvement
> Components: C++
> Reporter: Vibhatha Lakmal Abeykoon
> Assignee: Vibhatha Lakmal Abeykoon
> Priority: Major
>
> This is an extension to the ARROW-15590. The main focus is to address the
> following issues.
> 1. Support set of equality expressions as the join expression
> 2. Output handling (user provides the left and right outputs)
> 3. Support other (except INNER) join types: This requires mapping of existing
> Substrait Join definitions to Arrow supported Join types
> 4. Filter support: This requires mapping Substrait `post_join_filter` to
> `filter` in `HashJoinNodeOptions`
