@Marvin i want to set a timeout for a flow and then re-run the flow automatically if the flow timeouts. what are my options here? thanks

Setting a timeout for a flow in Prefect and handling retries on timeouts isn't directly covered in the snippets from the documentation, but we can infer some possible strategies: 1. Setting a Timeout: You can set a timeout for tasks within a flow using the

timeout

parameter in the task decorator. Here's an example of how to set a timeout for a task:

python
   from prefect import task

   @task(timeout=600)  # Timeout in seconds
   async def example_task():
       # Task implementation here
       pass

Unfortunately, this snippet doesn't handle the flow-level timeout; however, implementing similar logic at the flow level might look something like this (though not directly supported):

python
   from prefect import flow

   @flow(timeout=600)  # Hypothetical example, not supported in Prefect directly
   async def example_flow():
       # Flow implementation here
       pass

2. Auto-Retry on Timeout: For automatically re-running the flow if it times out, you might consider using Prefect's retry mechanism for tasks and apply similar logic for the flow, potentially by catching the timeout exception. Unfortunately, there isn't a native flow-level auto-retry on timeout feature, based on the retrieved documents. To set up automatic retries for tasks, you can do the following:

python
   from prefect import task

   @task(max_retries=3, retry_delay_seconds=10)
   async def example_task():
       # Task implementation here
       pass

Here's an example of how you could potentially look to set up a flow retry manually by controlling the execution through another function or system:

python
   from prefect import flow
   
   def run_flow_with_retry(retries):
       for _ in range(retries):
           try:
               example_flow()
               break  # Flow completed successfully, exit retry loop
           except TimeoutError:
               # Handle logging and waiting before the next retry
               pass
   
   run_flow_with_retry(retries=3)

However, these examples are hypothetical solutions and may not be directly applicable. For authoritative information, please refer to Prefect's official documentation for flows, and specifically look for information about flow-level timeouts and retries. If further detail is required, consider reaching out to the Prefect community support channels or checking the Prefect GitHub repository for any issues or discussions related to your query.
