Are there examples of using 1 flow to run 2 subflows in Prefect 2.0? The documentation is not very clear on the matter. How do I test it locally? On my firm's local server?

hi @Jason Motley - in prefect 2, you can simply call

@flow

-decorated functions from other

@flow

-decorated functions, for example

from prefect import flow

@flow
def foo():
   pass

@flow
def bar():
   for _ in range(3):
      foo()

if __name__ == "__main__":
   bar()
   # deploy this flow with bar.serve(__file__)

will run 3 subflows

what if foo and bar are in different python files?

just like python otherwise, you can import whatever objects you need, aliasing them as needed

from my_module import main_flow as this_specific_main_flow

@flow(name="some unique name")
def main_flow():
   this_specific_main_flow()

is this what you mean? prefect doesn't really care what the

__name__

of your flow function is, but if you're re-using names then I would pass a unique

name

to the decorator of each flow

yeah, so do I pass in "some unique name"? or do I pass in "main_flow" ?

the module import stuff should be entirely consistent with python, as in you could do

from my_package.module.submodule import some_defined_flow

# or 

from local_file import some_other_defined_flow

and as for the

name

kwarg to your flow decorator, its entirely up to you what you call your flows, but flows should have unique names

is

local_file

the flow name from the file or the actual name (

name="my_name"

)?

local_file

is a hypothetical file name in which

some_other_defined_flow

would be defined, like

# local_file.py

from prefect import flow

@flow(name="whatever")
def some_other_defined_flow():
   pass

Along these lines, if "my_file_1.py" is already running _and is part of this subflow, is there a way to skip that part of the refresh until it has finished running?_ Example: Flow 1 runs every hour and it is a subflow for an orchestration that runs every 8 hours. I don't want the overlap to occur every 8 hours.

im not sure i totally understand what pattern you're talking about - do you have a code example of what you're trying to do?
