Separate schedules for Azure webjob functions?

Question

Is it possible to set up separate schedules for individual non-triggered functions in an Azure webjob? I ask because I have half a dozen individual tasks I'd like to run at different times of the day and at different intervals and don't want to create a separate project for each.

Answer 1

Yes you can using the TimerTriggerAttribute

• Azure WebJobs SDK Extensions
• nuget download page

Here is a sample code:

public class Program
{
    static void Main(string[] args)
    {
        JobHostConfiguration config = new JobHostConfiguration();

        // Add Triggers for Timer Trigger.
        config.UseFiles(filesConfig);
        config.UseTimers();
        JobHost host = new JobHost(config);
        host.RunAndBlock();
    }

    // Function triggered by a timespan schedule every 15 sec.
    public static void TimerJob([TimerTrigger("00:00:15")] TimerInfo timerInfo, 
                                TextWriter log)
    {
        log.WriteLine("1st scheduled job fired!");
    }

    // Function triggered by a timespan schedule every minute.
    public static void TimerJob([TimerTrigger("00:01:00")] TimerInfo timerInfo, 
                                TextWriter log)
    {
        log.WriteLine("2nd scheduled job fired!");
    }
}

You can also use a CRON expression to specify when to trigger the function:

Continuous WebJob with timer trigger and CRON expression

Answer 2

I ended up using Quartz.net with a continuous job for scheduling various activities internal to the web job. This has worked very well.
