[rabbitmq-discuss] Retrieving the queue content with other clients waiting for messages

Hello all,

I'm trying to make an application sending jobs to the queue and
consumers getting jobs from it and processing them.

I also need a UI showing the status of each job: have it been only
submitted, is currently executing or finished.

Can I avoid storing this information outside the rabbitmq?

My idea is to have 3 queues: submited, executing and completed.

The application sends a job to submited queue. The workers wait for
new jobs to appear and move the job from submited to executing queue,
then after processing moves a job from executing to completed.

The worker will have to cycle through all the jobs in a queue and ack
the proper one. Also to get a status of a job, I could cycle for all
the jobs in Submited, Executing and Finished and remember where I
found the needed one.

The problem I'm having now is when there are consumers listening to a
new job, I can't connect another consumer to this queue and make a
basicRecover from it. It receives nothing.

Is there an easier way of doing it? Or do I have to use a database and
store the job state in it, updating when there are changes to the job

Thank you
