in order to get flow of flows to work, do i have to use wait_for_flow_a? or can i just create_flow_run and define upstream_tasks as previous create_flow_run?
So an example would be:
Copy code
with Flow("Flow_of_flows", storage=STORAGE) as flow:
child1 = create_flow_run(
flow_name="flow_child1",
project_name=PROJECT_NAME,
run_config=RUNCONFIG,
)
child2 = create_flow_run(
flow_name="flow_child2",
project_name=PROJECT_NAME,
upstream_tasks=[child1],
run_config=RUNCONFIG,
)a

yes, that works - the wait task is required if you need to start the next flow run only after the first once completed - it is essentially polling for the state of other flow run to determine whether to run downstream tasks or block and not run downstream tasks if e.g. one child flow run failed
