@Marvin can I run a task without contributing to the flow run final state?

From the information gathered on versions 2.x and 3.x of Prefect, it appears that you can't run a task without its state affecting the final state of the flow run. In Prefect, tasks are integral to determining the final state of a flow. Here's a brief explanation: ### Prefect 2.x In Prefect 2.x, all tasks contribute to determining the final state of the flow. Each task's state is considered when resolving the overall flow state. There is no direct method described to isolate a task's state from affecting the flow state. ### Prefect 3.x In Prefect 3.x, the behavior is similar. The final state of a flow run is determined by resolving all task futures to states and then evaluating these states to determine the final outcome. As of the latest documentation, there isn't a built-in mechanism to exclude a task's state from contributing to the final flow state. ### Example This behavior can be observed in the following simplified example for Prefect 3.x:
Copy code
python
from prefect import task, flow
from prefect.states import Completed, Failed

@task
def example_task():
    return Completed(message="Task completed successfully.")

@flow
def example_flow():
    state = example_task.submit()
In this example, the state of
example_task
will be considered when determining the final state of
example_flow
. For more detailed information, you can refer to the Prefect documentation: - Prefect 2.x Task Runners - Prefect 3.x Manage States Feel free to ask if you have more questions or need further assistance!
