[jira] [Created] (SPARK-36745) Cleanup pattern ExtractEquiJoinKeys

Yannis Sismanis created SPARK-36745:
---------------------------------------

             Summary: Cleanup pattern ExtractEquiJoinKeys
                 Key: SPARK-36745
                 URL: https://issues.apache.org/jira/browse/SPARK-36745
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 3.1.2
            Reporter: Yannis Sismanis


The join condition returned from ExtractEquiJoinKeys corresponds to the equi-join on the extracted keys only. A call site can be risky if it is not aware of that.

The pattern extractor should extract the rest of original join condition as well.
