How high scale Rails apps make schema changes

I recently wrote a post over on the PlanetScale blog sharing how we make schema changes for our own Rails app.

In the post I share a couple concepts that might be new to you.

  1. "Online" schema change tools
  2. Separating rails db:migrate from deploys

If your team or app is starting to grow and you're wondering what to look out for next. Give it a read, I hope you find it helpful.
