Mastering Redis

By: Jeremy Nelson

Overview of this book

Redis is the most popular, open-source, key value data structure server that provides a wide range of capabilities on which multiple platforms can be be built. Its fast and flexible data structures give your existing applications an edge in the development environment. This book is a practical guide which aims to help you deep dive into the world of Redis data structure to exploit its excellent features. We start our journey by understanding the need of Redis in brief, followed by an explanation of Advanced key management. Next, you will learn about design patterns, best practices for using Redis in DevOps environment and Docker containerization paradigm in detail. After this, you will understand the concept of scaling with Redis cluster and Redis Sentinel , followed by a through explanation of incorporating Redis with NoSQL technologies such as Elasticsearch and MongoDB. At the end of this section, you will be able to develop competent applications using these technologies. You will then explore the message queuing and task management features of Redis and will be able to implement them in your applications. Finally, you will learn how Redis can be used to build real-time data analytic dashboards, for different disparate data streams.

This chapter started with an in-depth exploration of how Redis handles and responds to client requests defined in multiple C header and code files. Then, we took a detailed look at the source code. We examined the processCommand function that works in relation to other functions and operations in Redis. We then went through an exercise where we added two new Redis commands by coping and retrofitting existing C code into our own development Redis branch.

The next sections were on the Redis Serialization Protocol and thewith a detailed byte-level examination of the Redis binary persistence format. We then looked at two different projects that use different Redis client implementations in Python and Node.js.

Now that you have a better understanding of what is under the hood of Redis, in Chapter 5, Programming Redis Part 2 – Lua Scripting, Design Patterns, and DevOps, we will show how to add complex server-side Lua programs to Redis instead of creating custom Redis commands. Chapter 5...
