## Description With the introduction of the authorization module, traversal of the MTree may no longer be a search of the whole tree. Fortunately, the PathPatternTree for authorization must consist of either a prefix or a fullPath. For example, `root.db.d1.s1` or `root.db.d2.**`. Therefore, we only need access to the subtree identified by the authorized PathPatternTree. The PathPatternTree of authorization can be easily converted to a deterministic automaton (DFA). In the MTree visitor framework, we can introduce a new member variable `scopeDFA` to restrict the search scope. Pruning will be done early when the search exceeds the `scopeDFA`. -- This is an automated message from the Apache Git Service.
