[GitHub] [arrow-datafusion] mingmwang commented on issue #4267: [EPIC]: reimplement all rules which contains global-state

   I think it depends on what the global-state is. If the global states are predicates or something related to Column/Exprs, then we should remove such kind of global states..   But for some optimization rules, it might be better to keep a global state so that it is easily to figure out a best plan.
