Overview of this book

RabbitMQ is an open source message queuing software that acts as a message broker using the Advanced Message Queuing Protocol (AMQP). This book will help you to get to grips with RabbitMQ to build your own applications with a message queue architecture. You’ll learn from the experts from CloudAMQP as they share what they've learned while managing the largest fleet of RabbitMQ clusters in the world. Following the case study of Complete Car, you’ll discover how you can use RabbitMQ to provide exceptional customer service and user experience, and see how a message queue architecture makes it easy to upgrade the app and add features as the company grows. From implementing simple synchronous operations through to advanced message routing and tracking, you’ll explore how RabbitMQ streamlines scalable operations for fast distribution. This book will help you understand the advantages of message queue architecture, including application scalability, resource efficiency, and user reliability. Finally, you’ll learn best practices for working with RabbitMQ and be able to use this book as a reference guide for your future app development projects. By the end of this book, you’ll have learned how to use message queuing software to streamline the development of your distributed and scalable applications.

Keeping queues and brokers clean

A clean broker is an efficient broker. To keep power and space at an optimum level, making sure queues and brokers are clean is easy. RabbitMQ provides mechanisms for auto-deleting messages and queues to keep space free. These include setting the time to live (TTL) and auto-deletion of unused queues, which are detailed in the following sections.

Setting the TTL for messages or the max-length on queues

Queues providing messaging support for long-running processes may grow extremely large. A too large queue might affect the performance of the broker. Setting the TTL allows messages to be removed from the queue after a certain time. If specified, these messages enter the dead letter exchange. This saves more messages and even handles potential issues without losing data.

Set a reasonable TTL with the x-message-ttl property when declaring a queue. Make sure to provide x-dead-letter-exchange and x-dead-letter-routing-key to avoid losing messages entirely.
