Delayed::Job: Open Source Background Job Processing System

Delayed::Job is an open source background job processing system for Ruby on Rails applications. It allows you to run asynchronous tasks outside of the request/response cycle, making the application more responsive.

What is Delayed::Job?

Delayed::Job is an open source background processing framework written in Ruby for scheduling asynchronous jobs in Ruby on Rails applications. It provides a simple interface for enqueueing tasks that can run in the background independently of the request/response cycle.

Some key features of Delayed::Job include:

  • Simple API for enqueueing and managing background jobs
  • Performant and scalable backend using an appropriate queuing backend like Redis, Sidekiq, etc.
  • Reliable job processing with automatic retries and failure handling
  • Flexible priority queue allowing urgent jobs to be processed ahead of other jobs
  • Easy to monitor, administer and scale up background job processing
  • Wide community support and ecosystem of third party gems/tools

By offloading time-consuming tasks like sending emails, image processing, PDF generation etc. to the background, Delayed::Job helps applications improve responsiveness and performance. It is a reliable and mature library for handling asynchronous/background tasks in Ruby on Rails apps.
