Redis's excellent performance is because it stores all the data in memory, the same memcached do, but why Redis can stand out, largely because Redis has excellent persistence mechanism to ensure that the server restart, the data will not be lost.

Redis master Copy This chapter describes a powerful feature of Redis – Master-slave replication. A master host can have multiple slave from the computer. And a slave from the machine can also have multiple slave from the machine. This continues to

Redis is a key-value storage system that is now used more and more in a variety of systems, mostly because of its high-performance features, and is used as a cache. Redis can also be applied to other scenarios because of its rich data structure.

For the second time today, I encountered the issue of Redis "Misconf Redis is configured to save RDB snapshots, but are currently not able to persist on disk." This error message is the exception information that the Redis client tool throws when it
