@xiedeyantu In the real production enviroment, we faced plan with massive CTE / unnest / join / aggreagte operations with large amount of nested fields in struct type. And different optimization stages(with different rule set) cannot use HepSubProgram. Because there is somes global variable need to set between diffierent stages. UnionTree with filter/projects with filter/project simplifiy rule is the simplest way to simulate a large plan. I think it is a simple benchmark to address the plan scalabiliy problem. Maybe we can create more complex plan generator to resolve different problem(e.g. test large armount of parents for same CTE) later. -- This is an automated message from the Apache Git Service.
