[jira] [Created] (ARROW-16485) Improving Substrait-Join Integration

Vibhatha Lakmal Abeykoon created ARROW-16485:
------------------------------------------------

             Summary: Improving Substrait-Join Integration
                 Key: ARROW-16485
                 URL: https://issues.apache.org/jira/browse/ARROW-16485
             Project: Apache Arrow
          Issue Type: Improvement
            Reporter: Vibhatha Lakmal Abeykoon
            Assignee: Vibhatha Lakmal Abeykoon


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`
