Hello everyone 
So i might have a rather dumb question, but i just could not find the answer anywhere, so …
Given that i have a workflow.py that imports some activities and other modules, i would put those imports within imports_passed_through, so that they are not re-imported for every workflow run (if im sure that they don’t case unwanted side-effects). So far i do understand the concept of sandboxing.
In the imported acitivity.py or helpers.py i now also import other modules, that i don’t want to be reloaded within the sandbox. Should i use imports_passed_through here, too, now? Or is imports_passed_through in the workflow.py recursive?
Also. Are acitvities themself also executed within an own sandbox? So do we need to use imports_passed_through here too, when they are executed for example by an own worker.
Thank you.
