It should be explained that the time complexity of these operations is O (1), that is, the constant time to complete the operation. The maximum number of elements a set can con

Similar to memcached, it supports storing more value types, including string (string), list (linked list), set (set), Zset (sorted set-ordered collection), and hash (hash type). These data types support Push/pop, Add/remove, and intersection-set and difference sets, and rich
