Redis的隐藏技能你可能不知道的秘密（redis隐藏功能）

Nowadays,Redis，an in-memory data structure store that can be used as a database, cache, and message broker，has gned great popularity with its blazing-fast performance。

Redis does much more than what you may assume by just looking at its name. Here I will introduce some hidden skills of Redis.

**1) Cross-platform:** Redis is based on win32, Linux, Mac and FreeBSD and is used without the need for any configuration. It is the most preferred database for deploying quickly on most used platforms.

**2) High Avlablity:** With Redis Sentinel, you can set up a highly avlable Redis service, which allows replication of multiple copies of the same data set. Even when the master server fls, Sentinel will ensure that the slave automatically takes over as the new master and keeps the service running.

**3) 6 data types :** Redis support six data types, such as strings, lists, sets, hashes, sorted sets, and bitmaps.

**4) Lua support :** Lua script support is an important feature of redis. With Lua, it’s possible to change a number of keys in a single atomic operation. It helps to perform sophisticated tasks such as recognition work.

**5) Pub/Sub :** Redis provides support for publish/subscribe (pub/sub) which is commonly used for communication between clients in a distributed system.

**6) Data persistence :** Redis can use data persistence to provide a variety of strategies: snapshots and append-only files, which can help when the server needs to recover from flure.

To sum up, Redis is a powerful data structure store with many hidden skills. With the above six hidden skills, Redis can improve user experience and development efficiency.
