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.

The Programmability of Redis Stack

In this chapter, we’ll explore Redis Stack’s programmability features and show you how they can be used in different situations. For quite a while, software engineers and database administrators have been making the most of stored procedures in relational databases. There are several good reasons for that: managing SQL procedures all in one place, easily troubleshooting procedure flows, staying separate from the chosen client library, and, most importantly, getting things done quickly.

Redis started off by allowing users to write Lua scripts and run them locally, giving them a taste of this capability. But with Redis Stack, server-side programming has been taken to a whole new level. You can now write intricate business logic in either Lua or JavaScript and execute it as close to your data as possible. There is no need for back-and-forth trips to a distant server.

In this chapter, we’ll show you how to implement complex...
