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.

Chapter 4. Programming Redis Part One – Redis Core, Clients, and Languages

In this chapter, Programming Redis Part One – Redis Core, Clients, and Languages, we'll start with a tour of the Redis C source code, examining how the major Redis C header and code files interrelate and work with each other, followed by a high-level code execution flow so that we can implement our own new Redis command. Then, to prepare for the next section on using Redis clients of two different programming languages, we'll do a detailed breakdown of the Redis Dump Binary (RDB) format, the binary format Redis uses in persisting snapshots of its database on disk. We will also cover the Redis protocol specification, the low-level communication format that clients use to communicate with the Redis server. Finally, we'll use these Redis clients and programming approaches in different use cases.
