This article shows you how many lines of redis source code, the code is concise and easy to understand, absolutely can make your eyes shine, through the detailed introduction of this article I hope you can gain something.

Redis is a high-performance key-value storage system written by Salvatore Sanfilippo, which is completely open source and free to comply with the BSD protocol. Redis and other key-value caching products (such as memcache) have several characteristics.

+ Redis supports persistence of data. It can save data in memory to disk and load it again for use when restarting.

+ Redis not only supports simple key-value data, but also provides storage for list, set, zset, hash and other data structures.

+ Redis supports data backup, namely master-slave mode data backup.

Redis has high performance and rich data types. At the same time, all operations in Redis are atomic, and it also supports atomic execution after several operations are merged. In addition, Redis has a wealth of extension features, it supports publish/subscribe, notifications,key expiration and so on.

Redis is more excellent place is that its code style is extremely concise, the entire source code is only 23000 lines, it is conducive to reading and appreciation! What are you waiting for? Start!

How to get Redis source code?

Redis is completely open source, and its source code is available directly on the website (the latest version is 3.2.5).

Git gets:

Source code Get git clone https://github.com/antirez/redis.git

Linux

cd ... //Open your redis folder here wget http://download.redis.io/releases/redis-3.2.5.tar.gztar zxvf redis-3.2.5.tar.gz

At this point, go to the src folder under the extracted redis directory, where all the source code of redis is stored.
