Ask HN: Have you had to switch / compensate your NoSQL DB with a relational DB?
Hey all,
I'm a long time Rails developer who has been on the MySQL / Postgres + Ruby/Rails + Redis stack. I've been playing with Node.js lately, and it seems that the Node community loves NoSQL.
I'd love to learn about projects that started out NoSQL, because of it's advantages of speed and scale but had to turn to a relational database for it's advantages - advanced querying, data integrity etc.
Thanks!
