Introducing New Book, RabbitMQ Essentials

Learn more about the ultimate RabbitMQ guide written by the experts at CloudAMQP!

Managing the largest fleet of RabbitMQ clusters in the world, CloudAMQP regularly shares tips, advice, and expertise through blog articles like this one. Sometimes we create video training for beginners and for experts or host live webinars on the finer points of RabbitMQ. Over the years, we have shared quite a lot of knowledge on message queues, so as an expert it was time for us to gather all of it in one comprehensive, organized way. Introducing the book RabbitMQ Essentials!

An excerpt from RabbitMQ Essentials, Chapter 1: A Rabbit Springs to Life Messages are typically small requests, replies, status updates, or even just information. On the surface, a message queue could seem kind of ordinary, but the reality is that they significantly simplify coding while having a major positive impact on scalability, reliability, and system performance. A successful message queue architecture is all about knowing how to organize, and that’s where RabbitMQ comes in.

Why did we write a book on RabbitMQ?

Blogging about RabbitMQ and creating video tutorials is great for sharing information on the latest FAQs and questions we hear from our customers and the community. The team decided to write a comprehensive guide to message queuing, one that users of any level would find useful and interesting. To drive home the factual, instructive points in the book, we would create a fictional company using RabbitMQ as its main platform to illustrate the flexibility and scalability that makes message queuing so powerful.

An excerpt from RabbitMQ Essentials, Chapter 4.Tweaking Message Delivery: The developers look at what is offered in terms of message expiration in RabbitMQ and list the following possible options that can be implemented:

  • Standard AMQP message expiration property for published messages
  • Custom RabbitMQ extension that allows users to define a message TTL per queue
  • Custom RabbitMQ extension that allows users to define a TTL for the queue itself

Custom RabbitMQ extension that allows users to define a TTL for the queue itself The first option is interesting because it is a standard AMQP option; however, after reading more about how it is supported in RabbitMQ, it turns out that these messages are only discarded when the message reaches the head, or beginning, of a queue. Even if they have expired, the messages would still sit in the queue, which would defeat the purpose of what they're trying to achieve.

What is covered in the book?

Whether you are an experienced developer who regularly relies on enterprise messaging products or just someone who enjoys the challenge of developing open-source applications, RabbitMQ Essentials is written for you. Follow along as the case study company uses microservice architecture to provide exceptional customer service and an enhanced user experience.
