azure - QueueTrigger Attribute Visibility Timeout

Question

If I were to get a message from queue using Azure.Storage.Queue

queue.GetMessage(TimeSpan.FromMinutes(20));

I can set the visibility timeout, however when trying to use Azure.WebJobs (SDK 0.4.0-beta) attributes to auto bind a webjob to a queue

i.e.

public static void ProcessQueueMessage([QueueTrigger("myqueue")] string message){
       //do something with queue item
}

Is there a way to set the visibility timeout on the attribute? There does not seem to be an option in JobHostConfiguration().Queues. If there is no way to override, is it the standard 30 seconds then?

I have the same question and haven't found answer yet. But, to answer a part of your question, the default lease is 10 minutes.

Quoting the Azure Website: "When the method completes, the queue message is deleted. If the method fails before completing, the queue message is not deleted; after a 10-minute lease expires, the message is released to be picked up again and processed. This sequence won't be repeated indefinitely if a message always causes an exception. After 5 unsuccessful attempts to process a message, the message is moved to a queue named {queuename}-poison. The maximum number of attempts is configurable."

Hope this helps!
