Yes, I saw performance issues on batch SDF. What is even worse is that this was not deterministic. We either have to (somehow) force redistribution on Reshuffle or use GBK-unGBK in the implementation of SDF. Prior to the change to hints, there was call to `rebalance`, which would be good enoughz although it was changed in order to not ignore chain of Reshuffles. I'm not sure why this matters, I will try to find more info. -- This is an automated message from the Apache Git Service.
