   > Can we have different physical optimizers list for the plans with/without unbounded sources?
   
   This would make sense to me if there are different query plans / decisions that would be made in the two modes.  It seems like the decision can be made locally at the moment by inspecting the plans / plan nodes, as suggested by @metesynnada 
   
   @mingmwang  do you have some ideas about when a global mode would be more beneficial?
