  An awesome asynchronous event-driven reactor for Ruby. (by socketry)

  

i think this announcement https://brunosutic.com/blog/async-ruby & the associated async libraries (https://github.com/socketry/async) do a much better job of showing off the potential for the ruby 3.1+ fiber scheduler. Async gem is powered by a fiber scheduler under the hood, and what you get is un-colored async-ready ruby code.

That is to say, you can write a normal rack app with falcon/async and get node/event-loop scale co-operative concurrency without changing your code. Its pretty exciting!

Unfortunately rails makes heavy use of Thread locals, so its going to take awhile until its async-ready, but I believe progress is being made (Async ActiveRecord was merged recently).
