@Marvin in prefect 2, how can i call a task with a specific timeout at runtime?
m
In Prefect 2.x, you can set a timeout for a task using the
timeout_seconds
keyword argument when defining the task. This allows you to specify the maximum duration a task is allowed to run before it is automatically cancelled. Here's a simple example:
Copy code
python
from prefect import task, flow

@task(timeout_seconds=60)  # Set a timeout of 60 seconds
def my_task():
    # Task logic here
    pass

@flow
def my_flow():
    my_task()

my_flow()
In this example,
my_task
will be cancelled if it runs for more than 60 seconds. You can adjust the
timeout_seconds
value as needed. For more details, you can refer to the Prefect 2.x documentation on tasks.

@Marvin can i change the timeout when i call
my_task()
from within
my_flow()
?

In Prefect 2.x, task timeouts are set at the task definition level using the
timeout_seconds
parameter, and there isn't a built-in way to dynamically change the timeout for a task at runtime when calling it from within a flow. The timeout specified in the task decorator is static and applies to all instances of the task. However, if you need to have different timeout values for different calls to the same task, you might consider defining multiple task functions with different timeout settings or using a parameter to control the logic within the task itself, though this won't change the timeout behavior directly. For more details, you can refer to the Prefect 2.x documentation on tasks.
