Change Time span of an existing job

question
1

In one of my methods i use BackgroundJob.Schedule to schedule a job with and time span of 5 minute.

BackgroundJob.Schedule(() => Console.WriteLine(“Hello, world!”), TimeSpan.FromMinutes(5));

However in those five minute time span if i receive an update,i need to be able to reset the time span to 5 minutes again.
I need to know if its possible to get the instance of a scheduled job and is it possible to reset the time span on the job ?.

i wonder if this is possible?

I am also wondering how this could be done.
Anyone from the Hangfire team looking into this? :smile:

Hangfire team, haha :smile: (the core team consist of one person yet) I’ve solved this issue by re-creating a job. To do this, you should save the job id somewhere. In my context, I needed to send a notification in time:

class Notification
{
    public int Id { get; set; }
    public int UserId { get; set; }
    public string Text { get; set; }
    public string JobId { get; set; }
}

To change the time span, just remove the background job and create a new one:

BackgroundJob.Delete(notification.JobId);
notification.JobId = BackgroundJob.Schedule(/* ... */);

I’ll also think how to simplify this solution in Hangfire itself.

@odinserj, did you ever had a meeting with yourself to discuss how to implement a feature? If so, you’re a team! :smile: haha
Thanks for the solution!
Cheers!

Yep, my split personality helps me a lot. One side proposes new features, other side refuses them, and third side makes the decisions :smiley:

Whoo hoo, I pretty much ended up doing the same as odinserj. The only odd thing is that your deleted items basket in dashboard is gonna be clogged: at least in my case it does. As this is not a big issue for me. I didn’t scratch my head over it. Anyways started to use hangfire in our dev environments, seems to be working without a glitch. Planing to move to our prod environment soon. :smile:
