To start a work pool that listens to a specific work queue in Prefect, you'll be dealing with the concept of workers and work pools. Depending on your Prefect version (2.x or 3.x), the steps are quite similar. ### Prefect 2.x 1. Create a Work Pool: Navigate to the Work Pools tab in Prefect UI and create a new work pool if you don't have one. 2. Start a Worker: - Open a terminal. - Activate your Python environment with Prefect installed. - Use the command:
prefect worker start --pool your-work-pool-name
This command will start a worker that listens to the specific work queue associated with your work pool. The worker will poll the Prefect API for tasks that it needs to execute and submit them accordingly. Keep the terminal active, or daemonize the worker for a production setting. Details here ### Prefect 3.x 1. Configure Work Pools: - Work pools in Prefect 3.x act like pub/sub topics connecting the deployments and workers. - They manage how flow runs are distributed and executed across different execution environments. 2. Manage Work Pools: - Create and manage them using the Prefect UI, CLI commands, REST API, or a Terraform provider. 3. Start a Worker: - Similar to Prefect 2.x, start a worker to patrol your work pool using a command such as
prefect worker start --pool your-work-pool-name
. The priority and status of queues are managed within Prefect, where queues receive tasks based on priority. Workers poll these queues and execute tasks accordingly. Learn more. Remember, the Prefect worker is an essential unit that continuously polls the work queue, making sure all tasks are executed as per their scheduling and priority. Just like a diligent robot but sadly without hopes or dreams—or arms and legs for that matter.

Can I not have two workers open on a remote, each listening to their own work queue?
Figured it out 🙂
