@Marvin, can you provide an example of how to use

prefect.events

emit_event

so that a task will wait for this event to be emitted by another task before proceeding?

To use

emit_event

in Prefect, you can send a custom event from one task and have another task wait for this event. Here's a concise guide on how to achieve this in Prefect 3.x: 1. Emit an Event: Use the

emit_event

function to send a custom event from a task. You'll need to specify the event name and a resource ID. Here's a basic example:

python
from prefect import task
from prefect.events import emit_event

@task
def emitting_task():
    emit_event(
        event="my_custom_event",
        resource={"prefect.resource.id": "unique_id_for_event"}
    )

2. Wait for an Event: Currently, Prefect doesn't natively support waiting for events in the way you might be used to with other systems. However, you can simulate this behavior by implementing a polling mechanism or using Prefect's state management features to coordinate between tasks. 3. Links and Resources: - Prefect Events Documentation: Learn more about emitting and handling events in Prefect. Given your preference for imperative programming, you might need to create a custom polling loop or use Prefect's state management to achieve synchronization between tasks. If Prefect introduces more direct event-waiting capabilities in the future, it would be worth revisiting their documentation for updates.
