The approach discussed today was that the GroupBy or HashJoin operator would inject an additional projection with the expression to compute the partition. This would then be computed all the way down into the scan potentially and be available for both the shuffle step and the operator itself without recomputing. The operator needs to then internally strip that additional column off before passing to its parent. -- This is an automated message from the Apache Git Service.
