If it is unordered, use set to store the user's unique ID, for example, SADD users {id} and then use a hash map to store the user's various properties, such as HSET user_{id} name "Tom" . So you can see the number of users in set, and then add and subtract in the set, the synchronization operation of the corresponding user in the hash line
