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.

Chapter 2. Advanced Key Management and Data Structures

Using Redis as data storage in your application starts by considering two sides of the solution: the keys and the data structures used as the key values in Redis. Coming up with a good Redis key schema, syntax, and naming convention can mean the difference between an effective and sustainable solution and a technological mess. Because of the flexibility that Redis gives you by allowing most string serialization as keys, much more intentional thought and design should be given to this important step in designing a Redis-based project. Likewise, using an appropriate data structure for any particular key also directly impacts the usability and functionality of any application built with Redis. This chapter covers the following:

  • Designing and managing a Redis key schema and the associated data structures

  • Using Redis client object mappers that use different strategies that hide the specific key schemas and data structures

  • Creating a simple application...
