Today, the editor shares with you about the more common application scenarios of redis, which many people do not know. Today, in order to let you know more about the more common application scenarios of redis, I have summarized the following contents for you. Let's look down together. I'm sure you'll get something.

Redis is a powerful memory storage with rich data structures, which can be used in many aspects, including database, cache, message queue and so on.

If you have the impression that Redis is just a key-value store, you're missing out on many of the powerful features of Redis. Here are five of the most common examples of real-world applications.

1. Full page cache

If you are using server-side content rendering, and you do not want to re-render each page for each request, you can use Redis to cache frequently requested content, which can greatly reduce the delay of page requests. There are many frameworks that use Redis to cache pages, which is a way of page static.

2. Ranking list

Redis is memory-based and can handle add and decrease operations very quickly and efficiently, and the performance improvement is huge compared to the way SQL requests are processed.

The ordered collection of Redis makes it easy to "get the highest ranked N elements from a large list", millisecond, and very simple.

3. Session storage

This is probably the most widely used point. Compared with session storage like memcache, Redis has the ability to persist cached data. When the cache is restarted due to problems, the previously cached data is still there, which is more practical and avoids the user experience problems caused by the sudden disappearance of session.

4. Queue

For example, email send queues, data queues waiting to be consumed by other applications, Redis can easily and naturally create an efficient queue.

5. Publish / subscribe

Pub/sub is a very powerful feature built into Redis, such as the ability to create a real-time chat system, notification triggers in social networks, and so on.

This is the end of the more common application scenarios of redis, of course, not only the above and everyone's analysis methods, but the editor can ensure its accuracy is absolutely no problem. I hope that the above content can have a certain reference value for everyone, and can be put into practice. If you like this article, you might as well share it for more people to see.
