Redis 4.x Cookbook

Overview of this book

Redis is considered the world's most popular key-value store database. Its versatility and the wide variety of use cases it enables have made it a popular choice of database for many enterprises. Based on the latest version of Redis, this book provides both step-by-step recipes and relevant the background information required to utilize its features to the fullest. It covers everything from a basic understanding of Redis data types to advanced aspects of Redis high availability, clustering, administration, and troubleshooting. This book will be your great companion to master all aspects of Redis. The book starts off by installing and configuring Redis for you to get started with ease. Moving on, all the data types and features of Redis are introduced in detail. Next, you will learn how to develop applications with Redis in Java, Python, and the Spring Boot web framework. You will also learn replication tasks, which will help you to troubleshoot replication issues. Furthermore, you will learn the steps that need to be undertaken to ensure high availability on your cluster and during production deployment. Toward the end of the book, you will learn the topmost tasks that will help you to troubleshoot your ecosystem efficiently, along with extending Redis by using different modules.

Optimizing replication


In the previous recipe, we talked about the basic workflow of Redis replication and learned how to set up a master-slave replication in Redis. While setting up replication is quite simple, there are many critical configuration parameters for Redis replication which deserve your special attention. Moreover, some default values of these parameters may even cause performance issues under certain circumstances. In the following two recipes of this chapter, we are going to discuss these configurations for the optimization and troubleshooting of Redis replication.

In this recipe, we will delve into a key parameter called repl-backlog-size to see how to tweak it in order to achieve a better performance for Redis replication by taking advantage of the partial resynchronization. In addition, some other parameters that may have an impact on the replication performance are also discussed.
