delayed-job

Is it possible to host the application in one server and queue jobs in another server? Possible examples: Two different EC2 instances, one with the main server and the second with the queueing service. Host the app in Heroku and use an EC2 instance with the queueing service Is that possible? Thanks Yes, definitely. We have delayed_job set up that way where I work. There are a couple of requirements for it to work: The servers have to have synced clocks. This is usually not a problem as long as the server timezones are all set to the same. The servers all have to access the same database. To do

I need to overwrite the Delayed::Worker.max_attempts for one specific job, which I want to retry a lot of times. Also, I don't want the next scheduled time to be determined exponentially (From the docs: 5 seconds + N ** 4, where N is the number of retries). I don't want to overwrite the Delayed::Worker settings, and affect other jobs. My job is already a custom job (I handle errors in a certain way), so that might be helpful. Any pointers on how to do this? I figured it out by looking through delayed_job source code. This is not documented anywhere in their docs. Here's what I did: class

Currently when I have a delayed method in my code like the following: CommentMailer.delay.deliver_comments(@comment, true) I write something like this in my spec: dj = mock("DelayProxy") CommentMailer.should_receive(:delay).and_return(dj) dj.should_receive(:deliver_comments).with(comment, true) Is there a better way to handle this and/or chained methods like that in rSpec in general? We can just have one more line in the before block as following: CommentMailer.stub(:delay).and_return(CommentMailer) Then you then can have the normal mock check as following: CommentMailer.should_receive(

The DelayedJob docs mention hooks, including an error hook, but only in the context of custom Job subclasses. This similar question (with no answers) says adding the same hook to the mailer class did not work. What's the trick? Update: In general, I'd like to see how to add hooks to jobs that are triggered using the object.delay.action() syntax, where I don't see an obvious link to a ____Job class. I was just searching for a solution to this problem too, and I found this gist . I don't know where it comes from (found it on Google), but well, it seems to do the job pretty well, is quite simple,

My environment is rails 3.1, heroku bamboo stack, delayed_job_active_record, (https://github.com/collectiveidea/delayed_job ) and experimenting with hirefire. (https://github.com/meskyanichi/hirefire) - I can see the delayed_job queue documentation, but how do I apply this on heroku? I have a max priority set of tasks that get spawned off every hour that I need to dedicate 3 workers to, it takes approx 26 minutes to complete. During that time, less important background tasks need to continue, with perhaps 1 worker dedicated to them. So I'll set that block of priority tasks to being in a named
