Noticed how I referenced 2 proper RDBMS in my question? Then how you proceeded to introduce another flavour-of-the-month

I haven't looked at Apollo, but GP should've explained that GraphQL is not a database and can be hooked up to any backend, so with it I'm guessing you can use any kind of database in Apollo/Meteor apps. Still, kind of weird.

Another reason why I never bothered with Meteor.

I remember when Meteor was the JavaScript flavour-of-the-month and everyone was saying it will kill Rails. I wanted to believe so I looked into Meteor, then I saw its dependence on MongoDB... Nope!

If you study the backend JavaScript ecosystem you'll see no Rails-like all-in-one framework has ever succeeded. They're just not part of the culture. The only Rails-like thing in the JS ecosystem that's popular and great is Ember but that's only frontend.

Did you look at the Apollo link? it allows you to use any db you choose. some of the starter apps use mongo,postgres, rest api. it's quite cool.

Sounds like Apollo can connect to both MySQL and Postgres (as well as other data stores): http://docs.apollostack.com/apollo-server/guide.html#Connect...
