This PR addresses one particular simplification rewrite mentioned in ticket [SYSTEMDS-3921] - the pushdown of a selection before a join it is dependent of. After introducing relational operators in SystemDS, simplification rewrites for those operators are required. With this rewrite possibility, the selection will be executed first and the join will then take the selection's output instead of the original matrix. Testing was designed and executed similarly to builtIn raSelection and raJoin-Tests. -- This is an automated message from the Apache Git Service.
