Mastering Redis

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.

Summary


This chapter started with a detailed examination of the Redis server scripting language called Lua before going into some examples of using Lua scripts with the EVAL command. This was followed by loading and then executing Lua scripts with the SCRIPT LOAD and EVALSHA commands. Next, we went back and saw how using Lua scripts can simplify the application logic in the earlier examples of the previous chapters, such the MARC21 ingestion, online stationery store, the linked data fragments server, and various node.js applications. The next section showed how in different Redis operational modes, such as Master-Slave replication and transactions, impact the Redis application design.

The final section was on how the role of Redis in the increasingly popular enterprise organizational structure called DevOps is flexible enough and well-suited for data storage and manipulation needs of both developers and operational staff.

In our next Chapter 6, Scaling with Redis Cluster and Sentinel, we will...
