Redis (How does MySQL and redis work together ?), Redismysql

Beginner:

Redis is also a server. It is mainly deployed on the server to relieve the pressure on the server. For high-traffic data, it can be cached to redis first. When users access redis directly, they no longer need to directly access the database, ease the pressure on the database. Mysql mainly stores data.

First, use MySQL to write data, and use redis to read data. Use Triggers between MySQL and redis to synchronize data.

Second, redis is used in some key areas. For example, if a result reads a large number of times, the result can be saved to redis, and redis will be read first.
Memcahe is mainly used for local cache file synchronization.
