Brand-new Rails 7 apps exceed Heroku’s memory quotas | justin․searls․co

In the history of Ruby on Rails, one of the healthiest pressures to keep memory usage down has been the special role Heroku has played as "easiest place to get started hosting Rails apps". In general, Rails Core and Heroku's staff have done a pretty good job of balancing the eternal tension between advancing the framework while still making sure a new app can comfortably run on Heroku's free (or now, cheap) "dyno" servers over the last 17(!) years. Being able to git push an app to a server and have everything "just work" has always been a major driver of Rails' adoption, and it's seen as obviously important to everyone involved that such a low-friction deployment experience—even if developers ultimately move their app elsewhere—is worth preserving. And that means being cognizant of resource consumption at every level in the stack.
