I can use Ruby on Rails but I don't think an RoR app can handle thousands of comments per minute in an optimised way. I run a midsize app in Rails 5 and already having lot of scaling issues.

Iirc Reddit stopped open sourcing their code from 2017 and I guess understanding and running that 12 year old spaghetti code wasn't worth it anyway. I don't see anything useful on their github page too https://github.com/reddit

Rails will handle "thousands of comments" just fine. If you are hitting scaling issues with a midsize Rails app you probably could look into how to optimize.

Throwing Mongo at the problem is not really a solution.

GitHub and shopify are written in RoR afaik, many millions of requests go through them just fine

Its not like reddit improved since 2017... they added silver, copper and a sucky new interface but I dont think that helps anyone.
