Hi @Florian L
, first off, glad you are enjoying Prefect! 🙂 To your question, there isn’t a best practice regarding that internal to Prefect, in the sense we don’t have any special cleaner utilities or processes. In general since results can be templated any way you like and with any backend you like, we envision any file rotation plan to be pretty personal. That being said if you have some ideas for how you might want a Prefect utility to look or work, that would be a good feature request github issue!
