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.

Task management with Redis and Celery

Celery, an asynchronous task queue project available at, is based on distributed message passing and allows execution of individual tasks. With Celery, you can specify different message broker backends, with Redis being one of the supported message brokers. In a basic use case for Celery, a Celery application or instance is created for handling such operations as creating tasks and managing workers that respond to those tasks.

To show how Celery can be used in a simple application, we'll implement an application based on the following scenario: a small school district with a single high school wants a class room reservation system for after-school activities. While there are many approaches you could take to create a simple room reservation system, we'll go ahead and build a Python-based system that uses Celery and Redis to manage the room reservations in this high school. Each room that is available for reservation will switch...
