Prefect Community

:wave: hullo! curious, in prefect 2 is there a way to set some flow-level context that are accessible by all sub-flows/tasks?

basically something like:

```@flow
def my_flow():
    context["my_cool_variable"] = "blah"
    my_subflow()


@flow
def my_subflow():
    print(context["my_cool_variable"])
    my_task()


@task
def my_task():
    print(context["my_cool_variable"])```
should have the output

```[my_subflow] blah
[my_task]    blah```


What happens if you define it outside tasks and flows? I think it might work

I would guess that does, but what if everything isn't colocated? i guess some funny things can happen there

another piece is...execution isn't guaranteed on the same instance right? so that adds some complexity

Well yes it might run into problems if things aren’t colocated but I think in general this global variable might be bad practice

we definitely can get around it by just passing things around in the arguments for tasks, but was curious
