> My suggestion is making the partition-aware optimization a configure option, but do not remove the code. > By default, we turn it off. So that the UnionExec just like a plain Union and do not keep the partition info. But that also means that if a user turns it on, DataFusion may produce incorrect results. I'm not sure this is a desired feature then. -- This is an automated message from the Apache Git Service.
