As best I can tell the Rama-awesomesauce is down in the backend modules, e.g. https://github.com/redplanetlabs/twitter-scale-mastodon/blob/f86abdb7c86e80bd57ad7

I'm trying to understand this as well based on the code you linked to and other comments - so the secret sauce of this implementation is the Rama library / framework / database? And that's closed source? Also looks like Rama itself is in beta right now? When will it be stable? Will it remain closed source at that point?

  No, sorry for any confusion: since this codebase is designed to be a showcase of how awesome programming in Rama is but it has (as the author claimed) 10k lines, then I would imagine an interested reader would want to know how does one use Rama's API to do Mastodon stuff, and skip past the Spring plumbing bits that are not Rama-ized (AFAIK) Thus, I found some of the .whatever("*awesome") looking code down in the guts of the backend module but since there is no other obvious tour of how the Rama works in this codebase, I thought I would draw the reader's attention to the interesting bits As for your other product related questions, that'd be much better as a top-level comment so nathanmarz can reply to them

    The Spring stuff and Rama stuff is split between the api/ and backend/ folders. The backend/ folder is the more interesting part to look at.

  The best resource for learning about Rama is its documentation: https://redplanetlabs.com/docs/~/index.html https://redplanetlabs.com/docs/~/index.html Our blog post about our Mastodon implementation is a deep dive into how it works, and how the implementation is utilizing Rama to do some really powerful things: https://blog.redplanetlabs.com/2023/08/15/how-we-reduced-the-cost-of-building-twitter-at-twitter-scale-by-100x/ https://blog.redplanetlabs.com/2023/08/15/how-we-reduced-the...
