Jianhui Dong updated CALCITE-4747:
----------------------------------
Description:
!image-2021-08-19-12-12-41-534.png!
After we use HepPlanner to optimize the RelNode, we need to replace old RelNode with the optimized RelNode, and update the graph in HepPlanner, but calcite only remove the outdated RelNode(HepRelVertex) in line 970. I think maybe we should also remove the outdated edge.
