This sounds ilke a cost model based decision -- I agree the fixed heuristics we have now aren't ideal but I think CBO based decisions suffer from similar challenges It would be sweet if there was some sort of API / framework that allowed downstream users to make this type of determiniation on their own (maybe a trait for heuristics / decisions made by the optimizer that people could customize 🤔 ) -- This is an automated message from the Apache Git Service.
