The search did not return specific information on how to configure Prefect flow idempotency behavior directly. However, Prefect Automations might be used to create triggers based on flow run states, which can be proactive (firing when certain thresholds are not met). This could potentially be used to trigger new flow runs if a flow fails, simulating non-idempotent behavior.
You might want to create an automation that starts a new flow run in response to a failed flow run. Here's the
documentation on Automations that may assist you in setting up proactive triggers.
If you still can't find what you're looking for, consider checking the
Prefect Discussions or opening a new issue in the Prefect GitHub repository for community input on idempotency behavior for failed runs.
