[jira] [Created] (CALCITE-2343) PushProjector with OVER expression causing infinite loop

Laurent Goujon created CALCITE-2343:
---------------------------------------

             Summary: PushProjector with OVER expression causing infinite loop
                 Key: CALCITE-2343
                 URL: https://issues.apache.org/jira/browse/CALCITE-2343
             Project: Calcite
          Issue Type: Bug
            Reporter: Laurent Goujon
            Assignee: Laurent Goujon


When applying the {{ProjectJoinTransposeRule}} on a project with a Rex expression containing a RexOver call (using HepPlanner), this might cause an infinite loop (and ultimately a StackOverflowError exception) as PushProjector identify the RexOver call as to be push down under the join, but doesn't not rewrite correctly the top Project expression.
