What kind of server is redis?

The most common use scenario of Redis is to cache data as a cache server, and one of the major characteristics of cached data is that the data is timed. After the data is loaded into Redis for caching, the data will expire after a certain period of time or according to a specific policy, and then be deleted.

There are two ways to automatically delete expired keys in Redis to keep the cached data timely:

1. Set the expiration time of the key

2. Set the Redis memory size. (after the key value in Redis reaches the maximum memory, find the invalid key waiting to be deleted according to the key elimination policy configured in the configuration file, and then delete it.)

The above is what redis refers to all the content of the server, thank you for reading! I believe we all have a certain understanding, hope to share the content to help you, if you want to learn more knowledge, welcome to follow the industry information channel!
