@Marvin in prefect 3, if a subflow in a flow fail. How to re-run that subflow without re-running the previous

In Prefect 3.x, if a subflow within a parent flow fails and you wish to re-run only that subflow without re-running previous tasks, you can utilize the concept of "resuming" a flow run. Prefect provides methods such as

resume_flow_run

which can be used to resume a flow from a particular state without restarting the entire flow. Here's a concise way to handle this: 1. Identify the Failed Subflow: When a subflow fails, its state will be marked as failed. You can retrieve this state using Prefect's logging and state management tools. 2. Resume the Subflow: Use the

resume_flow_run

method to resume the failed subflow. This method allows you to continue the flow execution from the point of failure. For more details, you might want to explore the Prefect 3.x documentation on flow states and resumption. Additionally, you can review the Prefect API for methods like

resume_flow_run

and related functionality to ensure you are using them correctly in your code. Here's a link to the Prefect API overview. If you'd like further assistance with the syntax or implementation, feel free to ask.
