> lgtm thanks @viirya I think we can let it move, Im thinking of abother thing: Spark most likely can figure out optimal join order, does that mean if DF has a fixed order than the same joined query run in Spark and Comet can have drastical performance downside? If so we probably may want to document is somewhere? Hmm, I don't understand the question. You mean if DataFusion has a different join order other than Spark, then Comet can have much better performance? We don't rely on DataFusion query optimizer but use Spark optimization. Comet's join order should be same as Spark. -- This is an automated message from the Apache Git Service.
