Learning RabbitMQ

Overview of this book

RabbitMQ is Open Source Message Queuing software based on the Advanced Message Queue Protocol Standard written in the Erlang Language. RabbitMQ is an ideal candidate for large-scale projects ranging from e-commerce and finance to Big Data and social networking because of its ease of use and high performance. Managing RabbitMQ in such a dynamic environment can be a challenging task that requires a good understanding not only of how to work properly with the message broker but also of its best practices and pitfalls. Learning RabbitMQ starts with a concise description of messaging solutions and patterns, then moves on to concrete practical scenarios for publishing and subscribing to the broker along with basic administration. This knowledge is further expanded by exploring how to establish clustering and high availability at the level of the message broker and how to integrate RabbitMQ with a number of technologies such as Spring, and enterprise service bus solutions such as MuleESB and WSO2. We will look at advanced topics such as performance tuning, secure messaging, and the internals of RabbitMQ. Finally we will work through case-studies so that we can see RabbitMQ in action and, if something goes wrong, we'll learn to resolve it in the Troubleshooting section.

Overview of RabbitMQ components

Before we dive into more details on the separate components of the message broker and their implementation, you can refer to Appendix A, Contributing to RabbitMQ on how to get the RabbitMQ source code so that you can review it as we move through the components and also how to install useful tools that will aid in Erlang development and RabbitMQ plugin development, in particular.

Boot component

The RabbitMQ boot component provides one of the key mechanisms in the message broker that allows the plugins to require certain steps from the RabbitMQ server in order to ensure that the components that they depend on are already loaded and it also allows the plugins to be installed and enabled in the RabbitMQ message broker. For this reason, it is advisable to write plugins with caution as they can crash the message broker if they are not implemented properly. Before the RabbitMQ boot mechanism is triggered, the common rabbit_sup process supervisor (the root of the RabbitMQ...
