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.

In this chapter, we covered in detail Redis support for the Publish/Subscribe messaging model with Redis's special Pub/Sub mode that clients enter when issuing either a SUBSCRIBE or with glob-style pattern matching variant PSUBSCRIBE Redis commands. When in Pub/Sub mode, other Redis commands cannot be used with the client and the client will monitor one or more channels for any incoming messages. Other clients can push messages to a channel using the PUBLISH Redis command, and all clients subscribing to that channel, either directly or through pattern matching, will receive those messages. To illustrate how to use Redis Pub/Sub with three different programming languages and clients, we constructed a simplified Kanban manufacturing process for constructing Jack-in-the-Box toys for a fictional North Pole company. We then examined two task and messaging frameworks – Celery and RestMQ – that use Redis to implement richer and more robust messaging for client applications, in this case...
