@Marvin, how can I cancel a submitted async task?

To cancel a submitted async task in Prefect, you can utilize the task's state management capabilities. Prefect tasks can be cancelled by setting their state to a terminal state such as "Cancelled". However, the specific method to cancel an async task isn't directly documented in the excerpts I found. Here's a general approach: 1. Retrieve the Task Run ID: You need to have the task run ID for the task you want to cancel. This can often be obtained from the flow run context or by querying the Prefect API. 2. Set the Task State: Use the Prefect client to set the task's state to "Cancelled". This can be done using the Prefect API. Here's a rough example of how you might do this:

python
from prefect import get_client
from prefect.states import Cancelled

async def cancel_task_run(task_run_id):
    async with get_client() as client:
        await client.set_task_run_state(task_run_id, Cancelled())

You can explore more about task state management and the Prefect API in the task engine source code. For more detailed guidance, you may need to refer to the official Prefect documentation or the Prefect GitHub repository. If you have more specific requirements or encounter issues, feel free to ask!

@Marvin, how can I cancel a submitted async task in prefect 2.x?

In Prefect 2.x, cancelling a submitted async task generally involves setting the task's state to a terminal state like "Cancelled". Here's a general approach: 1. Retrieve the Task Run ID: You'll need the task run ID, which can be obtained from the flow context or by querying the Prefect API. 2. Set the Task State to Cancelled: Use the Prefect client to update the task's state to "Cancelled". This can be done using the Prefect API. Here's a basic example:

python
from prefect import get_client
from prefect.states import Cancelled

async def cancel_task_run(task_run_id):
    async with get_client() as client:
        await client.set_task_run_state(task_run_id, Cancelled())

This example assumes you have access to the task run ID. For further details, you may want to explore the Prefect 2.x documentation or check the Prefect GitHub repository. If you have more specific requirements or encounter any issues, feel free to ask!
