Hangfire - Prevent multiples of the same job being enqueued

Question

Scenario:

Job 1 is scheduled to run every 5 minutes, and takes ~1 minute to complete.

A lot of work piles up and Job 1 takes 15 minutes to run.

There are now three Job 1's being processed concurrently - I don't want this.

---

How do I prevent Job 1 being added to the queue again if it is already there?

Is there Hangfire setting, or do I need to poll job statuses manually?

Answer 1

You can use DisableConcurrentExecution attribute to prevent multiple executions of a method concurrently. Just put this attribute above your method -

[DisableConcurrentExecution(timeoutInSeconds: 10 * 60)]
public void Job1()
{
    // Metohd body
}
