It's hard to calculate the cost of a shuffle and compare it with the benefit of skew join handling. We need some ways to tune it manually. But I don't understand why this patch is so complicated. Isn't it simply skip counting the shuffles at the end of `OptimizeSkewedJoin`? ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
