Concurrent Ruby with Tasks
Yes, you read the title correctly. And yes, ruby still has a GIL. However, ruby has long been able to support concurrency for IO-bound calls. Ruby will not block the current thread if it is waiting on IO. In practice, this means that many of our ruby programs (like web applications) can use ruby’s threads to concurrently serve multiple requests. Working directly with ruby’s threading primitives can be complicated. This is a problem that the concurent-ruby library aims to solve. This library is mature and comprehensive but it offers a staggering number of APIs for modeling concurrency in your application. ...
