I've been learning RabbitMQ various topologies, however, I couldn't find any reference to dynamic queue creation (aka Declare Queue) emitted from a producer. The idea would be to create queues dynamically depending on a particular event (e.g a HTTP request). The queue would be temporary with a TTL set and named after the event ID. A consumer could then, subscribe to the topic "event.*" and merge all the messages related to it.
Example:
Now, is this scenario feasible with RabbitMQ ?
Essentially, what you want to do is use RabbitMQ to buffer messages waiting in a set of queues (which is what a message queuing system does by definition). :)
Assuming you know what your queues are from the consuming side, you won't have any issues. There is no constraint that a producer can't create a queue. As a caveat, when queues expire, all messages in the queue are discarded (or optionally, they can be set to go to a dead-letter queue).
What code have you tried?
Upon further clarification (from your comment) - you are looking for "wildcard consuming" vs wildcard publishing. RabbitMQ does not support such a topology at the present time (this post asks for a similar feature).
What you would need to do is periodically enumerate the queues (using the RabbitMQ API); following that, your app could decide which ones to consume from. When a queue is deleted, the consumer is automatically closed.
Special Note It should be understood that what is being asked here is an anti-pattern. The typical behavior of a system using queues is to route messages to queues based upon content. Thus, a properly-orchestrated system would have a set of workers operating on one or more statically-defined queues. Different workers may take different queues, depending upon specialization. When a series of interactions results in messages being published to the queue, the workers assigned to the queues will handle the messages in a first-come-first-served fashion (but, as this post discusses, order cannot be guaranteed with multiple consumers). The desired system behavior then emerges as a composition of workers performing various functions operating on queues.
