This article focuses on "Why to use redis cache", interested friends may wish to take a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn "Why use redis cache"!

This problem is mainly viewed from two aspects: "high performance" and "high concurrency".

High performance:

If the user accesses some data in the database for the first time. This process will be slow because it is read from the hard drive. The data accessed by the user is stored in the cache so that the next time the data is accessed, it can be obtained directly from the cache. Operation caching is the direct manipulation of memory, so the speed is quite fast. If the corresponding data in the database changes, the corresponding data in the cache can be changed synchronously!

High concurrency:

Direct operation of the cache can withstand far more requests than direct access to the database, so we can consider transferring some of the data in the database to the cache, so that part of the user's requests will go directly to the cache without going through the database.

At this point, I believe that everyone has a deeper understanding of "Why to use redis cache", might as well come to the actual operation! Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
