Overview

Async Rails 3.1 introduces an exciting way to handle asynchronous operations in a Rails application using Fibers and EventMachine. This stack allows developers to perform non-blocking operations, enabling multiple requests to be processed simultaneously without the need for multiple threads. It’s particularly beneficial for applications with high concurrency requirements, as it efficiently manages database and HTTP requests.

However, it's important to tread carefully with this setup as it can lead to stack overflow errors if not managed properly. The stack overflow risk is notably exacerbated by the 3.1 release of Rails, making awareness of the limitations crucial for developers.

Features
