Hi, I was expecting the plans generated by standard_join_search to have lower costs than the plans from GEQO. But after the results I have from a join order benchmark show that GEQO produces plans with lower costs most of the time!
I wonder what is causing this observation? From my understanding, standard_join_search is doing a complete search. So I'm not sure how the GEQO managed to do better than that. Thank you, Donald Dong
