Turn a function into a outflow task

Let’s say you have this function :

def do_stuff():
    # some computation

To turn this function into a outflow task, you only need to add the @as_task decorator :

def DoStuff():
    # some computation

The decorator @as_task turns a function into a class so it may be better to use the class naming convention here

Specifying the outputs of a task

Tasks usually return some data for the next task. You have two choices to define the outputs of your tasks :

Alternative way: Target.output decorator

@Target.output("returned_data", type=int)
def DoStuff():
    ret = #some computation
    return {
        "returned_data": ret
