Thank you very much Jonathan for your very intuitive analogy! Basically I just want to put "people", "journal" and "tag" tables(each will potentially be very large) into different DBs, if I write that logic, how can I integrate it with SQLAlchemy? Could you give me a rough idea here? Or point some reference. I suppose such feature is relatively commonly needed among SQLite users isn't it?
