By: Luigi Fugaro, Mirko Ortensi

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.

Running health checks

Redis is a powerful, yet simple-to-use, open source data structure server that is designed for high performance and scalability. One of the core principles behind Redis is simplicity, which is reflected both in its design and its architecture. And the question “Is my Redis ready?” finds its answer in the redis-cli tool.

Verifying whether the installation has been completed correctly is as simple as running the following command in a terminal window:

redis-cli –h 127.0.0.1 -p 6379 PING
PONG

This is the most reliable and secure way to check whether Redis is up and running. If it is, a PONG response message will be given. Failing that, an alternative message will be reported, as follows:

redis-cli –h 127.0.0.1 -p 6379 PING
LOADING Redis is loading the dataset in memory

Automating the health check for Redis is possible using the redis-cli executable. This means that scripts can be written to interpret the output message from...
