1. In Redis, not all data is stored in memory, which is the biggest difference compared to memcached.2. Redis not only supports simple k/v types of data, but also provides storage of data structures such as List,set,hash.3. Redis supports backup of data, that is, Master-slave mode of data backup.4.

Memcached's distributedAs described in the 1th time, memcached is called a "distributed" cache server, but there is no "distributed" functionality on the server side. The server-side only includes the memory storage features introduced in the 2nd and 3rd times, and its implementation is very simple. As for the distribution of memcached, it is fully implemented by the client library. This distribution is the

about RedisRedis is one of the NoSQL (no only SQL, non-relational) databases that NoSQL stores data in the form of Key-value. The current mainstream distributed cache technology has REDIS,MEMCACHED,SSDB,MONGODB and so on. Redis can be understood as a caching technique, because its data is cached from it, and it can be understood as a database, because

Redis has created a new way of storing data. When using redis, we don't have to focus on how to put elephants in the refrigerator in the face of monotonous databases, instead, redis uses flexible data structures and data operations to build different refrigerators for different elephants. Common redis Data Types
