Quick question, if you’re running Prisma w. Yoga, is there any reason to choose MySQL over MongoDB and vice versa?

It depends on what you want to build. The main reason to use MongoDB over SQL are embedded types. If you think those are important for you go with Mongo otherwise use SQL.

Great! Thank you for the answer

Or if you want total order isolation (required by some laws) then pick mysql/postgres. I use postgres for all my prisma stuff, it has been smooth sailing.
