redis was released in 2009. The developer Salvatore Sanfilippo wanted to develop a product to replace MySQL for his company. Unexpectedly, he made Redis open source and became very popular. In just a few years, Redis has become very popular. Large user base.
Redis is widely used in environments with high concurrency and low latency requirements. , currently redis has always been relatively reliable in the DB-Engine monthly ranking list https://db-engi nes.com/en/ranking Previously, and has always been the first of key-value storage class .
Zhihu.com , Sina Weibo , GitHub and more and more companies are using Redis, and it has also become one of the skills questions that big companies must ask in interviews.
Today I will share with you "Redis Actual Combat Learning Manual" and "80 Redis Interview Questions" , which have been compiled into PDF and available for download. If you need it, see the way to get it at the end of the article!

Redis practical learning manual
1. The concept of cache
cache is to adjust the speed of two or more different substances with inconsistent speedIn the middle, the faster side plays a role in accelerating the slower side. For example, the CPU's primary and secondary caches store the data that the CPU frequently accesses recently, and the memory stores the data that the CPU frequently accesses the hard disk. Moreover, hard disks also have caches of different sizes, even the raid cards of physical servers have caches, all for the purpose of accelerating the CPU to access hard disk data, because the CPU speed is too fast, the data required by the CPU is often not available in the hard disk. Meet the needs of the CPU in a short time, so the PCU cache, memory, Raid card cache, and hard disk cache meet the data requirements of the CPU to a certain extent, that is, the CPU reads data from the cache can greatly improve the work efficiency of the CPU.
