[rabbitmq-discuss] Python & RabbitMQ — Communicate Between Parent & Children?

Fri Jul 15 22:51:00 BST 2011

Jason,

Thank you for your help.

The workers' messages to the parent are independent of the parent's message to the workers. These are two separate things that work in parallel. 

Note that the parents sends *the same message* to all workers, while (separately) each one of the workers sends *its own unique message* straight to the parent.

I am brand new to rabbitMQ -- is it possible to provide some further info / code snippets that would allow me to get a better sense of things?

Thanks,
Shalom.

Are the workers' published message replies to the parent's messages or
independent? If the latter, it sounds like a fanout exchange with a
private queue per work would work for the parent->child communication,
and then create a private anonymous queue for the parent and set the
"reply-to" header on the parent's messages to the name of it's private
queue. The children processes can then publish directly to that queue.
