The book is good about the theory about the RabbitMQ. It goes into details of the several concepts; however, it lack a bit about practical use of RabbitMQ.
Do not recommend. Poorly written, confusing and superficial. The book doesn't go deep into concepts and in later chapter says "as we explained before...".
A great read about RabbitMQ presented with comprehensive examples in multiple languages. I was slightly disappointed with the amount of theoretical knowledge the book contained. At times the book suggested that it would go into a lot of detail about a certain subject and it would later go into a bit more detail, but still not as in depth as I would have liked. The online resources for RabbitMQ on the official site are still far more useful to gain any knowledge about the product. I was surprised by how many typos and grammar errors had got through the editing process with this book, but luckily these did not make the book any less readable. It was still a useful book for my recent research into various message brokers.
