Now that we know the basics of Delayed Jobs and Sidekiq, let's dive deeper into their differences and what each brings to the table. Sidekiq claims that ActiveJob is about 2-20x slower when pushing to Redis, with ~3x the processing overhead. The ActiveJob::TestHelper also makes testing enqueued jobs a breeze.īut the abstraction provided by Active Job also comes with a performance overhead, as job data has to be wrapped before it's pushed to the store.
#DELAYED JOB ENQUEUE CODE#
The advantage of running jobs with Active Job is that your application code becomes framework agnostic, and switching from Delayed Job to Sidekiq (or vice versa) becomes pretty easy. Just inherit from ApplicationJob and call perform_later on your job class to enqueue the job to the configured queuing backend. Rails already provides a mature job framework for top-level declaration and handling of jobs.īoth Delayed Job and Sidekiq support running jobs through ActiveJob's unified API. Using Active Job with Delayed Job or Sidekiq The Sidekiq 'Getting Started' guide explains this and other usage patterns in good detail. To enqueue the job, we need to call perform_async(arg1, arg2) on the worker with the arguments. In addition to this, each Sidekiq process spawns multiple threads to process the jobs even faster.įor each background job in Sidekiq, we need a specialized class that includes the Sidekiq::Worker concern and responds to the perform method. This comes with the obvious benefit of being much faster than the regular database systems Delayed Jobs uses. Sidekiq, on the other hand, uses Redis as its data store to maintain all job metadata. If you have too many jobs queued at the same time, you might need more disk space to accommodate them all. However, it will still take up space in your database table. They don't need to spend/maintain other resources.

Many teams choose Delayed Job because it is simple and uses their already existing database.

The Delayed Job README does a great job of explaining all common usage patterns. It will process the method in the background. In addition, if you don't need to maintain special job objects (although this is highly recommended for testability and clear separation of long-running operations), it also allows you to call. Any Ruby object that responds to a perform method can be enqueued in the jobs table. Let's go! A Quick Introduction to Delayed Jobĭelayed Job is a direct extraction from Shopify and uses a table to maintain all background jobs. In this post, we will take a detailed look at Delayed Job and Sidekiq, including how they fare against each other. Several gems support job queues and background processing in the Rails world - Delayed Job and Sidekiq being the two most popular ones. It will run higher priority jobs first, and then lower priority jobs, in fact queue name doesn't matter after a job is enqueued, unless you have dedicated workers, when you define queues with priority: Delayed::Worker.Most applications need background jobs for mailers, regular clean-ups, or any other time-consuming operation that doesn't require a user to be present. Will it run along withĪnother queues or wait for them to execute first? Give it low priority, then how it will work. I also want to understand if I create a separate queue for rake task & Recommend change Delayed::fault_priority to a positive number, for example: 5, then define a priority method in the user workers return a lower number class UserRequestJob < ApplicationJob But I want to run the request from user first & then the rake task.
