How is the data stored on the backend?

I spent a long time going through the forum posts and can’t seem to find a simple answer to a simple question. What I gathered is that bubble uses AWS (at least for storage I think). Does that mean the back-end of bubble is a relational database, like MySQL? Also, when I create a “Type”, does bubble create an actual database table on a relational server (with indexes for fast lookups), or is the data stored similar to No-SQL (like documents)? This information might help me understand how I can expect my application to scale, and best practices going forward, thanks.

Hi, @JamesW did you ever find out the answer of this?
