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.

Types of integrations

Let's take a look at the standard setup that we have been discussing so far (including a producer, consumer, and three-node RabbitMQ cluster):

If we consider the client domain (publisher/subscriber), we can perform the following:

  • We can use a client AMQP library written in any programming language (thus integrating RabbitMQ with a particular programming language). We are already using the out-of-the-box RabbitMQ Java client. As RabbitMQ supports a multitude of AMQP clients, you can use one that best suits your application or write your own AMQP client in your programming language of choice, if one is missing.

  • We can use a wrapper library written on top of a client library. Many applications that use RabbitMQ as a message broker are deployed as part of a web or dependency injection container. For this reason, there are wrappers around the client libraries for different containers, such as the ones provided by the Spring framework and implemented on top of the RabbitMQ Java...
