"How much memory is my queue using?" That's an easy question to ask, and a somewhat more complicated one to answer. RabbitMQ 3.4 gives you a clearer view of how queues use memory. This blog post talks a bit about that, and also explains queue memory use in general.

One of the goals for RabbitMQ 3.3 was that you should be able to find bottlenecks in running systems more easily. Older versions of RabbitMQ let you see that you were rate-limited but didn't easily let you see why. In this blog post we'll talk through some of the new performance indicators in version 3.3.

Preventing Unbounded Buffers with RabbitMQ

Different services in our architecture will require a certain amount of resources for operation, whether these resources are CPUs, RAM or disk space, we need to make sure we have enough of them. If we don't put limits on how many resources our servers are going to use, at some point we will be in trouble. This happens with your database if it runs out of file system space, your media storage if you fill it with images and never move them somewhere else, or your JVM if it runs out of RAM. Even your back up solution will be a problem if you don't have a policy for expiring/deleting old backups. Well, queues are no exception. We have to make sure that our application won't allow the queues to grow for ever. We need to have some strategy in place to delete/evict/migrate old messages.

This provides us with a bit of control over how RabbitMQ will deliver messages to consumers in order to obtain a different kind of scheduling that might be beneficial for our application.

When would you want to use Consumer Priorities in your code?
