Hi Devs, Does anyone know what's the difference between the OptimizedHybridHashJoinOperatorDescriptor and the HybridHashJoinOperatorDescriptor?
I was going over part of the join codes and found both of these classes there. It seems the only difference between the two is when there is a hashFunctionFamily is null, we will use the HybridHashJoinOperatorDescriptor. However, it seems this would not happen... In fact, I changed to code to always use the optimized one and no test cases fail (could be test cases bias though). Thanks ahead! Best, Xikui
