Top 11 Ruby Concurrency Projects

  • Concurrent Ruby

    Modern concurrency tools including agents, futures, promises, thread pools, supervisors, and more. Inspired by Erlang, Clojure, Scala, Go, Java, JavaScript, and classic concurrency patterns.

    • Project mention: Concurrent-ruby (async) S3 files download | dev.to | 2024-05-17

    Let’s say we need to traverse through thousands of files in our S3 Storage in a Ruby app. Let’s say we have a bunch of logs there that we need to read every day and process. If we just use a straightforward approach, like opening, reading, and processing every file one by one, our solution will work, but It will take a lot of time to process. So we need to improve the speed. Here ruby-concurrent gem is our helper https://github.com/ruby-concurrency/concurrent-ruby. Why do we need this gem? Because It’s simpler to use than Threads and this gem has a lot more features in It. In this article, we will use Concurrent::Promises.future as the most common use of concurrent code. Because reading a file from S3 is an IO operation, we can get a huge benefit in speed if we gonna use concurrent code doing HTTP requests. Remember that concurrency will not give you speed improvements if in every Promise or Thread you will do any calculations. Because of Ruby GIL, every thread will be blocked until calculations are finished.

    • Project mention: Shoes makes building little graphical programs for Mac, Windows, Linux simple | news.ycombinator.com | 2024-02-23

    As someone who has looked at Shoes several times but never dove in, it's confusing how Shoes 4 has been the "preview version" of Shoes for, like, a decade or more. It made me actively avoid getting invested in Shoes 3 (the release promoted on the linked website) because Shoes 4 requires JRuby and I am happy with CRuby (the Ruby interpreter most people think of when they hear "Ruby").

    http://www.rubydoc.info/github/shoes/shoes4

    No disrespect to the developers but to me it feels like taking over a GUI toolkit created "to teach programming to everyone" (to quote the Shoes 4 readme) and making it depend upon a super-complicated enterprise-focused Ruby was sort of Missing The Point™ in a huge way.

    Heck I couldn't even switch to JRuby if I wanted to because I <3 Ractors and JRuby still lacks CRuby 3.0 feature parity: https://github.com/jruby/jruby/issues/7459

  • Async Ruby

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

    • Project mention: EventMachine Performance Spikes | /r/ruby | 2023-09-05

    The Async gem is the natural successor, It's actively maintained, and allows you write synchronous code is if it wasn't non-blocking, and most libraries don't need any special support for Async (exceptions are gems with C extensions that do I/O and DB libraries with connection pooling that would otherwise be thread-based).
