This article introduces the relevant knowledge of "what is the difference between redis and memcached". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

For redis and memcached, I summarized the following four points. Now companies generally use redis to implement caching, and redis itself is becoming more and more powerful!

Redis supports richer data types (supporting more complex application scenarios): Redis not only supports simple KBH data, but also provides storage of data structures such as list,set,zset,hash. Memcache supports a simple data type, String.

Redis supports data persistence, which can keep the data in memory on disk and can be loaded and used again when rebooting, while Memecache stores all the data in memory.

Cluster mode: memcached has no native cluster mode and needs to rely on the client to write data to the cluster, but redis currently natively supports cluster mode.

Memcached is a multithreaded, non-blocking IO multiplexing network model; Redis uses a single-threaded multiplex IO multiplexing model.
