    1.Join is Cross Product)
      1.1. Get Push Info
        1.1.1. Get Push Candidate Info
          1.1.1.1 Join has one side that has aggregate without
                  any cardinality augmenters above (Non push side)
          1.1.1.2 Join's other side has no agg or there is
                  a cardinality augmenter above it (Push Side)
        1.1.2. Max cardinality of Non Push Side is 1 and
               all of GB/AggFn keys are deterministic
        1.1.3. All of agg exprs come from push side
        1.1.4. None of GB exprs include attributes from both sides &
               there exists GB exprs from push side
        1.1.5. If pushside child is project then Translate AggFns, GB Keys below project
