Overview of this book

In modern applications, efficiency in both operational and analytical aspects is paramount, demanding predictable performance across varied workloads. This book introduces you to Redis Stack, an extension of Redis and guides you through its broad data modeling capabilities. With practical examples of real-time queries and searches, you’ll explore Redis Stack’s new approach to providing a rich data modeling experience all within the same database server. You’ll learn how to model and search your data in the JSON and hash data types and work with features such as vector similarity search, which adds semantic search capabilities to your applications to search for similar texts, images, or audio files. The book also shows you how to use the probabilistic Bloom filters to efficiently resolve recurrent big data problems. As you uncover the strengths of Redis Stack as a data platform, you’ll explore use cases for managing database events and leveraging introduce stream processing features. Finally, you’ll see how Redis Stack seamlessly integrates into microservices architectures, completing the picture. By the end of this book, you’ll be equipped with best practices for administering and managing the server, ensuring scalability, high availability, data integrity, stored functions, and more.

Summary

Redis not only can be adopted safely as a primary database in many use cases, but it is also the best option in many terms. Secondary indexing of Hash and JSON documents together with the ability to perform complex and hybrid multi-field queries and with basic analytical processing capabilities makes Redis, Redis Stack, and the commercial Enterprise and Cloud versions full-fledged data management systems with full support for scalability and availability. While NoSQL databases don’t generally fulfill the ACID properties but privilege availability over consistency, we have gone through the assumptions that help maximize the consistency of Redis databases against crashes, either in the standalone or replicated deployments.

Compromising on data integrity, consistency, and durability may not be an option, and in this chapter, you have learned to achieve the most durable configuration in Redis with the safest (but much less performing) AOF persistence policy. You have...
