+1， but why including root, i think the user could ignore the "root" when we change sg to database. And we could ignore the root in the file path. And, the sql select from root.dbname and select from dbname all are ok to keep compatible.

Currently, the maximum length of database name, including "root.", is *64* and it is immutable. Such constraint can help avoid some bugs of database and region management, since we use database names in the directory name, which shall not exceed the max name length defined by file system. best regards ------------------------ Yukun Zhou, Tsinghua University
