In Rails, concurrency is often handled through Active Job for background tasks, leveraging tools like Sidekiq for multi-threaded job processing. For simpler cases, you can use Ruby's Thread or Fiber, though it's less common due to Ruby's Global Interpreter Lock (GIL). Rails 7 introduces support for asynchronous queries with ActiveRecord::FutureResult. For external I/O, libraries like Concurrent-Ruby or Async can help manage concurrency effectively. Typically, Rails emphasizes simplicity and offloading intensive tasks to background jobs rather than using goroutine-style patterns directly.
