Why do we store queue contents in a single node in the RabbitMQ cluster rather than replicating it over all nodes?
What types of cluster nodes does RabbitMQ support? What is the purpose of each of them?
What type of data is being sent between the nodes of a cluster?
How do nodes in a RabbitMQ cluster communicate?
How can you add a node to a cluster?
How can you remove a node from a cluster?
How can you check the cluster status?
What happens to the subscribers of a queue if its node goes down?
What considerations should be taken into account when deploying RabbitMQ cluster nodes on different machines in the network?
What drawbacks can you mention in the clustering mechanism provided by 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.
