delayed_jobs vs resque vs beanstalkd?

Here is my needs:

  • Enqueue_in(10.hours, ... ) (DJ syntax is perfect.)
  • Multiply workers, concurrently. (Resque or beanstalkd are good for this, but not DJ)
  • Must handle push and pop of 100 jobs a second. (I will need to run a test to make sure, but I think DJ can't handle this many jobs)

Resque and beanstalkd don't do the enqueue_in.

There is a plugin (resque_scheduler) that does it, but I'm not sure of how stable it is.

Our enviroment is on amazon, and they rolled out the beanstalkd for free for who has amazon instances, that is a plus for us, but I'm still not sure what is the best option here.

We run rails 2.3 but we are bringing it to speed to rails 3.0.3 soon.

But what is my best choice here? Am I missing another gem that does this job better?

I feel my only option that actually works now is the resque_scheduler.

Edit:

Sidekiq (https://github.com/mperham/sidekiq) is another option that you should check it out.

What is delayed job?

Delayed Job uses your database as a queue to process background jobs. If your app has a high database load using DelayedJob may not be a good background queueing library for your app. To get started using Delayed Job you need to configure your application and then run a worker process in your app.

How do I know if my job is running late?

The most simple way to check whether delayed_job is running or not, is to check at locked_by field. This field will contain the worker or process locking/processing the job. Running Delayed::Job. where('locked_by is not null') will give you some results, if there are jobs running.

How do you restart a delayed job?

Restart Delayed Job on deploy You must remove that one now if you have it. It basically does the same thing that we will add now but without using upstart. We will now create a new file that will host our start, stop and restart tasks. Create a file at lib/capistrano/tasks/delayed_job.

For my projects I will feel very comfortbale with collectiveidea/delayed_job in rails2 and 3. I don't know beanstalkd, but i will try it soon :-). I have followed the suggestions in the resque documentation. I will report it.

Resque vs DelayedJob 

How does Resque compare to DelayedJob, and why would you choose one over the other?

  • Resque supports multiple queues
  • DelayedJob supports finer grained priorities
  • Resque workers are resilient to memory leaks / bloat
  • DelayedJob workers are extremely simple and easy to modify
  • Resque requires Redis
  • DelayedJob requires ActiveRecord
  • Resque can only place JSONable Ruby objects on a queue as arguments
  • DelayedJob can place any Ruby object on its queue as arguments
  • Resque includes a Sinatra app for monitoring what's going on
  • DelayedJob can be queried from within your Rails app if you want to add an interface

If you're doing Rails development, you already have a database and ActiveRecord. DelayedJob is super easy to setup and works great. GitHub used it for many months to process almost 200 million jobs.

Choose Resque if:

  • You need multiple queues
  • You don't care / dislike numeric priorities
  • You don't need to persist every Ruby object ever
  • You have potentially huge queues
  • You want to see what's going on
  • You expect a lot of failure / chaos
  • You can setup Redis
  • You're not running short on RAM

Choose DelayedJob if:

  • You like numeric priorities
  • You're not doing a gigantic amount of jobs each day
  • Your queue stays small and nimble
  • There is not a lot failure / chaos
  • You want to easily throw anything on the queue
  • You don't want to setup Redis

Choose Beanstalkd if:

  • You like numeric priorities
  • You want extremely fast queue
  • You don't want to waste you RAM
  • You want to serve high number of jobs
  • You're fine with JSONable Ruby objects on a queue as arguments
  • You need multiple queues

In no way is Resque a "better" DelayedJob, so make sure you pick the tool that's best for your app.

A nice comparison of queueing backend speed:

                 enqueue                work ------------------------------------------------- delayed job |   200 jobs/sec     120 jobs/sec resque      |  3800 jobs/sec     300 jobs/sec rabbitmq    |  2500 jobs/sec    1300 jobs/sec beanstalk   |  9000 jobs/sec    5200 jobs/sec 

Have a nice day!

P.S. There is a RailsCast about resque, Delayed Job (revised version) and Beanstakld. Have a look!

P.P.S. My favourite choiche is now Sidekiq ( very Simple, Fast and efficient for simple jobs ), have a look at this page for comparison.
