I am putting together an interface for our employees to upload a list of products for which they need industry stat’s (currently doing ’em manually one at a time).
Each product will then be served up to our stat’s engine via a webservice api.
I will be replying. The Stat’s-engine will be requesting the “next victim” from my api.

Each list the users upload will have between 50 and 1000 products, and will be its own queue.
For now, Queues/Lists will likely be added (& removed via completion) aprox 10-20 times per day.
If successful, traffic will probably rev up after a few months to something like 700-900 lists per day.

We’re just planning to go with a simple round-robin approach to direct the traffic evenly across queues.
The multiplexer would grab the top item off of List A, then List B, then List C and so on until looping back around to List A again … keeping in mind that lists/queues can be added/removed at any time.

The issue I’m facing is just conceptualizing the management of this.
I thought about storing each queue as a flat file and managing the rotation via relational DB (MySQL). Thought about doing it the reverse. Thought about going either completely flat-file or completely relational DB … bottom line, I’m flexible.
Regardless, my brain is just vapor locking when I try to statelessly meld a variable list of participants with a circular rotation (I just got back from a quick holiday, and I don’t think my brain’s made it home yet 😉

Has anyone done something like this?
How did you handle it?
What would you improve if you had to do it again?

Any & all tips/suggestions/advice are welcome.

NOTE: Since each request from our stat’s engine/tool will be separated by many seconds, if not a couple minutes, I need to keep this stateless.

    After a good nights sleep, I now have my wits about me (I hope :).
    A simple solution is a flat file for the priorities.
    Have a text file simply with one List/Queue ID on each line.
    Feed from one end of the list, and add to the other … simple.

    Criticisms are welcome ;o)

    Thanks @Trylobot and @Chris_Henry for the feedback.
