Redis is a key-value database; For redis, key is a string type, and value is only a binary string, redis does not care about its content; Using different commands, redis decides to store values in a specific data structure; For example, if you use

1. In master-slave replication, databases are divided into two types: master database and slave database for data synchronization ). The master database can perform read/write operations. When data changes due to write operations, the data is

RedisIs a key-value storage system. Similar to memcached, But it solves the problem that data is completely lost after power-off, and she supports more undefined value types. Besides string, it also supports lists (linked list), sets, and zsets.

Problems with traditional MySQL + memcached Architecture MySQL is suitable for storing massive data. Many companies have used this architecture to load hotspot data to the cache through memcached to accelerate access. However, as the business data
