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 to automatically transfer in the event of a failure is a problem that needs to be solved.Through the search for some information on the Internet, it is recommende

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 may p
Redis is a memory database that supports richer value types than memcache, and Sina Weibo uses Redis for caching.

A major system fault occurred on Weibo a few days ago, and many technical friends are concerned about it. The reason for this is no more than James Hamilton's onThe first experience of James, design for failure, is the key to the success of all Internet architectures. The engineering theory of Internet systems is actually very simple. James paper's content is almost not a theory, but a number of practical experiences are shared. Each company's understanding and execution of these experiences det

The ' $ ' logo is followed by the bulk reply protocol, to be resolved in bulk reply format;
' 3 ' represents the bulk reply length of 3 bytes;
"Set" is the bulk reply agreement content;
Repeat 2-4 until the protocol resolution is complete.
It can be seen that the generation and resolution of the protocol can be simplified as a two-paragraph text handler.
