Look Ma, No Background Jobs: A Peek into the Async Future
summary
Claims that external API calls and other IO-bound work no longer require background jobs because requests can yield to other work instead of blocking, using Falcon and the Async gem to run those operations on lightweight ruby fibers. Shows how to replace enqueue-and-wait patterns with direct async handlers inside the request cycle, reports practical latency and scalability improvements for IO-bound endpoints, and provides runnable patterns and configuration tips that actually eliminate the need for background queues.
