delayed_jobs vs resque vs beanstalkd?_问答_开发者

Here is my needs:

Enqueue_in(10.hours, ... ) (DJ syntax is perfect.)
Multiply 开发者_如何转开发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.

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.

Amazon Beanstalk isn't Beanstalkd.

Beanstalkd - the queue - does have delayed jobs, that won't be reserved out of the queue until the given number of seconds have passed. If that is what Enqueue_in(10.hours, ... ) means, then it's just syntactic sugar to calculate the number of seconds, and not make a job available till then.

Just a small note: delayed_job 3.0+ supports named queues

object.delay(:queue => 'tracking').method    
Delayed::Job.enqueue job, :queue => 'tracking'    
handle_asynchronously :tweet_later, :queue => 'tweets'
