Specify Job Timeout On Method

question
1

I have a method that I want to run in the background called GenerateDocument. I only want this to try to run for xx seconds before giving up. Is there a way to do this with Hangfire?

so in my method declaration I would have:

[Queue("critical")]
public int GenerateDocument(IDocumentSettings settings)
{
    //my method stuffs here
    return 12345;
}

Is there something that I can specify that i only want it to run for so many seconds and then have the CancellationToken throw an exception?

Did you find a solution for this?

There’s no way to terminate the job without terminating the entire worker thread. But you can construct your own cancellation token which would cancel after specified time:

public async Task GenerateDocument(CancellationToken cancellationToken)
{
    var timeout = TimeSpan.FromSeconds(10);

    using (var timeoutTokenSource = new CancellationTokenSource(timeout))
    using (var linkedTokenSource = CancellationTokenSource.CreateLinkedTokenSource(cancellationToken, timeoutTokenSource.Token))
    {
        try
        {
            await TimeLimitedOperation(linkedTokenSource.Token);
        }
        catch (OperationCanceledException) when (!cancellationToken.IsCancellationRequested)
        {
            // ignore OperationCanceledException if terminated because of timeout
        } 
    }
}
