When we sync a database to Metabase (Bigquery for example) Is the data being replicated to Railway? When you save models or questions, does that data now live on the server?

I'm sorry but unfortunately I wouldn't know how to answer that question properly as I do not utilise metabase myself, I would suggest asking that question in the metabase community or their forums as that question does have slightly more to do with metabase than the Railway platform.
