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.

Case study: introducing high availability in CSN

With the increase in utilization of the CSN, it was decided to establish additional mechanisms that would allow a more resilient day-to-day usage of the CSN. The system was performing well but with no guarantees in respect of information loss. Since event propagation is considered a highly important concept in the normal operation of the CSN, message loss in that area was established as a major risk. For that reason, the team decided to apply additional mechanisms for minimizing that risk. In particular, the innovations that were introduced were:

  • Support for automatic recovery in the CSN web and worker nodes and the browser plugin.

  • Support for publisher confirms when sending messages from the web node.

  • Additional remote RabbitMQ instance for the purpose of disaster recovery. The CSN web and worker nodes and the browser plugin were enhanced to take the remote instance into consideration upon automatic recovery (by extending those nodes with the...
