Yannis Sismanis updated SPARK-36745:
------------------------------------
Description:
The join condition returned from ExtractEquiJoinKeys does not correspond to the
equi-join on the extracted left and right keys. 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.

The join condition returned from ExtractEquiJoinKeys corresponds to the
