In Spark, `sort time total` only includes time of memory sorting, where there are spills, it is significantly sorter than the real computation time. In Auron, `Native.elapsed_time` means the summarized time cost for computation in this operator (excluding time of waiting for inputs and blocking for outputs). note this is different from original Spark because Spark uses row-based computation and whole-stage codegen, it is hard to count time for computation. -- This is an automated message from the Apache Git Service.
