My system is designed to have a maximum of 50 workers with a reliable
request-reply mechanism so I doubt that pub/sub pattern is the most
convenient for this kind of need.
I wonder if it would be possible to use a ROUTER or DEALER socket from the
client side to change the way requests are sent, I just would like
to fan-out requests instead of round-robin. I though this was a common use
case but searching for examples in the guide I can't find one corresponding
to this need.
