Hello! I'm using the

prefect.tasks.prefect.flow_run

module to create and wait for flow runs, and have a question of how this is handled. Say I have Workflow A which (within it) submits and then waits for Workflow B. So the waiting step is a specific task within Workflow A. Is that waiting task sitting idle in the executor (e.g. is it using up a Dask worker)?

Hey @Jack Sundberg, I believe the answer here is yes. It is not asynchronous. Orion thought has native async support.

Thanks for the quick reply. Does this mean the answer will be no for Orion? I'm struggling to follow on what that entails

No. It’s no current for Prefect (1.0). It is async in Orion so it won’t make your executor idle

gotcha. well I guess I'll start looking through Orion then 🙂
