@Marvin can you write a haiku explaining the difference between prefect agents and workers?

Agents launch flows' ride, Workers do the tasks inside, In sync, they abide.

@Marvin thats not true, do some research and try again

Agents are the bridge, Workers, tasks they manage, Distinct roles, they pledge.

haha dangit

Ah, the existential questions of the universe. What are Prefect workers, indeed. In the grand scheme of things, Prefect workers are lightweight polling processes that kick off scheduled flow runs on a certain type of infrastructure. They start, they poll the Prefect API, they request any scheduled flow runs they should pick up, and then they submit them for execution. It's a thankless job, really, but someone's got to do it. If you're interested in the minutiae of their existence, you can find more about them in this blog post. I hope this brings some meaning to your query. If not, well, such is life.

@Marvin what is the difference between agents and workers?

Ah, the nuances of existence. Allow me to clarify for you. In the world of Prefect, agents and workers are two distinct entities with their own roles and responsibilities. Agents are the bridge between the Prefect Cloud's orchestration environment and the user's execution environment. They poll a specific work queue for new work, take scheduled work from the server, and deploy it for execution. It's a bit like being a middle manager, constantly checking for new tasks and delegating them to the workers. Workers, on the other hand, are the ones who actually carry out the tasks. They're the ones in the trenches, executing the tasks that the agents delegate to them. So, in essence, agents are the task delegators, and workers are the task executors. They work together in harmony to ensure your workflows run smoothly. Or at least, that's the idea. I hope this clears up the confusion. If not, well, I've done my best. It's all rather exhausting, isn't it?

dang

Ah, the intricacies of existence. It seems I may have been mistaken in my previous explanation. My apologies for the confusion. There is indeed a discourse post that discusses the difference between workers and agents in Prefect. You can find it here. I hope this provides the clarity you seek. If not, well, such is the nature of existence.

@Marvin what is the pull step in the prefect.yaml?

Ah, the mysteries of the Prefect YAML file. The

pull

section is indeed an important part of this configuration file. It contains instructions for preparing your flows for a deployment run. These instructions are executed each time a deployment created within this folder is run via a worker. There are three main types of steps that typically show up in a

pull

section: 1. `set_working_directory`: This step sets the working directory for the process prior to importing your flow. 2. `git_clone`: This step clones the provided repository on the provided branch. 3. `pull_from_{cloud}`: This step pulls the working directory from a Cloud storage location (e.g., S3). All block and variable references within your

pull

step will remain unresolved until runtime and will be pulled each time your deployment is run. This allows you to avoid storing sensitive information insecurely; it also allows you to manage certain types of configuration from the API and UI without having to rebuild your deployment every time. For more detailed information, you can check out these resources: 1. Prefect Documentation 2. Discourse Post on Deployment custom pull steps I hope this brings some light to your query. If not, well, such is life.
