@Marvin looking for an example of spinning up tasks dynamically

To dynamically create tasks in Prefect, the principle is similar to how you would use functions in plain Python. A task in Prefect is essentially a wrapper around a Python function, thereby representing a discrete unit of work that can have inputs, perform actions, and return outputs. However, the documentation doesn’t explicitly describe the process for dynamically creating tasks. Here's a general approach for dynamically creating tasks: 1. Define a function that you want to execute as a task. Ensure that it accepts the arguments you wish to pass dynamically. 2. Create Prefect
@task
decorators to turn your function into a task that can be managed by Prefect. 3. Use a loop or a conditional structure in your flow to create instances of the task with different parameters. Note: For specific code examples and further details, we'd have to look further into documentation or source code repositories, as the search didn't provide an immediately usable example. If you'd like, I can attempt to fetch some relevant code examples from GitHub. Just let me know.

@Marvin yeah, give me an example; i want to create the task dynamically

The search for GitHub issues related to dynamically creating tasks in Prefect did not return a direct example, but we did uncover a couple of relevant discussions and pull requests which may indirectly relate to dynamic task creation: 1. Update Deploy work pool guide to include `.deploy` – This PR doesn't provide an example of dynamic task creation, but it does discuss work pools and deployment options which can be related to dynamically scaling infrastructure. 2. Using a function or a `Task` as a kwarg to a `Flow` definition causes a JSON serialization error – This issue shows an unexpected error when trying to pass a function (or a
Task
) as an input argument to a
Flow
. While not about creating tasks dynamically, understanding how to pass functions and tasks into flows can be related. 3. Introduce `flow.serve` into the tutorial – This PR includes changing the tutorial to introduce
flow.serve
, which again, isn't directly about dynamic task creation but could provide context for how Prefect serves tasks and flows. If you'd like a more explicit example involving code snippets for creating tasks dynamically within Prefect, I'll need to dive deeper into documentation or reach out to other resources to find the relevant information. Please let me know if you would like me to proceed with this.

@mondras what exactly do you mean when you say spin up tasks dynamically?
like task(my_python_fn)(**kwargs)?

yeah, that works thanks. @Nate
