Ruby 3.3, released with significant improvements in concurrency capabilities, marks a pivotal shift in how Ruby applications handle parallel processing and concurrent operations.

This advancement is particularly crucial as modern applications increasingly demand efficient handling of multiple tasks simultaneously, especially in domains like AI and ML.

This article explores Ruby 3's concurrency ecosystem, its various concurrency models, and their practical applications in modern software development.

Ruby's concurrency ecosystem has evolved significantly, offering developers multiple tools and abstractions to handle concurrent operations effectively.

The ecosystem now includes improved implementations of Threads, Fibers, and the revolutionary Ractor system, along with various libraries and frameworks that leverage these features.

Explanation: This example demonstrates a thread pool-based web crawler that efficiently fetches multiple URLs concurrently. It uses the concurrent-ruby gem's FixedThreadPool to manage a limited number of threads, preventing resource exhaustion. The Promise class handles asynchronous operations and error handling, making it ideal for I/O-bound tasks like HTTP requests.
