How does Ruby on Rails handle asynchronous tasks?

The question is about Ruby on Rails

Answer:

Ruby on Rails itself processes the so-called asynchronous tasks with the help of background job processing libraries like Sidekiq, Resque, or Delayed Job. These utilities allow the developer to move resource-intensive operations like sending emails or heavy data processing to the background workers without blocking the main application itself. ActiveJob in Rails provides an abstraction layer to these libraries, making managing and running background jobs pretty easy without the application being coupled to any particular job processing tool.
