Description:A Web service, the original business logic is to cache the results of the MySQL query in Redis for one hours, speeding up the response of the request. One problem now is that the response of the corresponding encoding is returned based

Application ScenariosWe want to reduce the database pressure by reducing the number of queries to the relational database through caching. In the execution of the DAO class select***() , the query***() method, the first Redis query from the cache

Redis is a key-value type of in-memory database, and Redis is more powerful than memcached. 1. Redis supports two methods of data persistence: snapshotting (snapshot) and Append-only file (append) 2, Redis not only supports simple key-value, but

Background introduction:Currently, Redis does not have an official HA scenario similar to MySQL proxy or Oracle RAC.The master-slave switching scheme named Sentinel has been formally provided #Redis version 2.8 (attached, not tested)Therefore, how

As a server program, Redis is the key to network IO processing. Unlike memcached, Redis uses libevent, which implements its own IO event framework and is simple and compact. You can choose Select, Epoll, Kqueue, and so on.As an IO event framework,
