　　Redis's set is an unordered collection of type string. The set element can contain a maximum of (2 of 32 square-1) elements. The set is implemented by hash table, so the complexity of adding, deleting, and finding is O (1). The hash table is

Introduction to the NoSQL Redis:Remote Rerictionry Server is a persistent database storage system based on Key-value key-value pairs, and the Redis and memcached caching services are similar.However, Redis supports a richer variety of data storage
