I encountered the similar issue before when we were implementing `PartitionGraph` pass in BYOC. We then had a group merging mechanism as you mentioned. I didn't quite get the point of using preorder to solve this problem. Is this because the first/input nodes of a pattern are impossible to be optional? ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
