Q:

RabbitMQ naming convention for queues and exchanges? 

I came across a statement in a tutorial on Udemy, that it is "good practice" to prefix queues with q. and exchanges with x. 
Unfortunately, I could not really verify that anywhere... Is there any convention like this, or a resource that pointed this out? 

A:

Don't know about prefixing queues with q. and exchanges with x.. But, it is considered a good practice to prefixing or suffixing your mirrored queues or exchanges with the keyword mirror.  
In a cluster system, you will be needing policies which will help you mirror your queues and exchanges.  In order to identify which queues are to be mirrored, the keyword, mirror will help.  And the queues which you don't want to mirror, you can add a keyword no_mirror.  In case of exclusive queues, you can prefix or suffix with ex. 
Also adding the word q or queue to the queues and x to exchange will enhance readability.
