Guide ​

Redis is the most widely used middleware in storage systems within internet technology architecture. It is also one of the most favored engineering skills questioned by interviewers during technical interviews for mid-level and senior backend engineers, especially at competitive large internet companies (such as Twitter, Sina Weibo, Alibaba Cloud, Tencent Cloud, Taobao, Zhihu, etc.). These companies often require candidates not only to grasp the basics of Redis but also to have a deep understanding of its internal implementation details. It is no exaggeration to say that if you fully master all the knowledge points of Redis, you will have one foot firmly in the door of your desired company’s technical research and development department.

The knowledge points related to Redis are numerous. This tutorial will primarily explain the most common core principles and practical experiences of Redis, allowing readers to quickly equip themselves for everyday Redis project development after reading. Additionally, it will delve into some crucial foundational principles of computer science and the thought processes behind technical applications, as this foundational knowledge and skill will ultimately determine how fast and far you can go in your technical career.

Content Structure ​

The content is divided into five sections: Redis Basic Applications, Principles, Clusters, Advanced Learning, and Source Code Analysis:

1. Redis Basic Applications: This section occupies the longest length and provides the most valuable content for readers, which can be directly applied to practical work.

2. Principles and Clusters: This section is suitable for developers with a strong pursuit of technology who wish to see the exquisite underlying world beyond simple technical surfaces.

3. Advanced Learning: As a supplementary part beyond the core content, this section mainly aims to further expand technical horizons or solidify fundamentals, facilitating advanced learning. The author will continuously add more knowledge points in the expansion sections.

4. Source Code Analysis: This section primarily satisfies the strong desire of advanced users to deeply explore Redis's internal implementations. These readers believe that understanding the source code is the true reflection of technical strength.

5. Visual and Animated Demonstrations: The tutorial will include rich visuals and animations to enhance understanding.
