[rabbitmq-discuss] Exclusive Producers?

[Tarun Mistry]

Hi all,

i'm new to RabbitMQ/AMQP. I am trying to solve an application level 
high-availability problem and belive i'm not thinking about things in the 
right way, I could use some advice!

Here is what I would like to achieve, I could use some help understanding 
the RabbitMQ way of doing it.

1) I have several message producers, only 1 of these is the primary, the 
remainder as all backups. 
2) The primary is defined as the process that controls a single queue and 
can post messages to it.
3) If the primary process fails, I want a backup to take over immediately.
4) All backups are in a race to get control of the queue (from 2)
5) Once a backup gains control, it is now the primary.

Using Rabbit speak, I feel like I need something called an "exclusive 
producer". 

Do I need to fudge this by introducing a second queue and having all the 
processes connect to this using the "exclusive consumer" pattern, and then 
use this to determine who can control the main queue?

Appreciate any advice

Cheers
TM
