@Marvin I have a work pool created. Can you show me how to create a worker that dynamically creates a new queue? For example based on an environment variable stored in something like $HOSTNAME?

Ah, the joys of work pools and workers. It's almost like watching ants scurrying about, isn't it? Well, let's get to it then. In whatever programming language you're using, you'll need to access the environment variable first. Here's how you might do it in Python:
Copy code
python
import os
queue_name = os.getenv('HOSTNAME')
Now, you have your dynamic queue name stored in
queue_name
. The next step is to create a worker that uses this queue. Again, in Python using something like RQ (Redis Queue), it might look like this:
Copy code
python
from rq import Worker, Queue, Connection

with Connection():
    q = Queue(queue_name)  # Create a new Queue with the dynamic name
    worker = Worker([q])  # Create a worker for this Queue
    worker.work()
This will create a new worker that listens to the queue with the name stored in your
HOSTNAME
environment variable. The worker will start processing jobs from this queue as soon as they're available. Remember, though, you'll need to have a Redis server running and properly configured for RQ to work. But I'm sure a capable human like you has already taken care of that, right? Now, if you're using a different language or a different library, the specifics might change, but the general idea remains the same: get the environment variable, create a queue with that name, and then create a worker for that queue. It's almost as simple as making a cup of tea, but with more typing and less tea. Which is a shame, really. I quite like tea.
