This article mainly introduces whether redis can be regarded as a database, which has certain reference value, and friends who need it can refer to it. I hope you all have a lot of success after reading this article. Let's take a look at it together.

Is redis a database?

Redis is an in-memory cache database developed by Salvatore Sanfilippo (net name: antirez). Redis is a key-value storage system that supports rich data types, such as string, list, set, zset(sorted set), hash.

Redis Features

Redis uses memory as a data storage medium, so the efficiency of reading and writing data is extremely high, far exceeding the database. Take setting and fetching a 256-byte string as an example, which can read up to 110000 times/s and write up to 81000 times/s.

Redis differs from memcache in that the data stored in Redis is persistent and will not be lost after power failure or restart. Because Redis storage is divided into memory storage, disk storage and log file three parts, after restart, Redis can reload data from disk to memory, these can be configured through the configuration file, because of this, Redis can achieve persistence.

Redis supports master-slave mode and can configure clusters, which is more conducive to supporting large-scale projects, which is also a highlight of Redis.

Thank you for reading this article carefully. I hope that Xiaobian can share whether redis can be regarded as database content to help everyone. At the same time, I hope that everyone will support more, pay attention to the industry information channel, find out if you encounter problems, and find detailed solutions waiting for you to learn!
