 ##  Namespace
 
 Namespace is used to isolate data between users. Unlike all the Redis databases can be visited by `requirepass`, we use one token per namespace. `requirepass` is regraded as admin token, and only admin token allows to access the namespace command, as well as some commands like `config`, `slaveof`, `bgsave`, etc..
