Extend the initialVisibility Delay for an existing CloudQueueMessage for Azure Message Queue

Question

I am trying to achieve the following flow using Azure Message Queue as illustrated in the following diagram :

So, the client initially creates and adds a message in the queue with initialVisibiltiyTimeout of 5 minutes.

_queueResolver.GetQueue("my-queue")
                          .AddMessage( new CloudQueueMessage(json), initialVisibilityDelay: TimeSpan.FromMinutes(5));

The challenges that I encountered so far are related to the ability to extend the initialVisibilityDelay period for the initial message that has been sent. I am not sure how can I retrive the message from the queue. What are the best practices in this cases ? Do I need to persist in other store the id's of the messages that are on the Queue ?

Unfortunately it is not possible to fetch a message set with initial visibility delay until the time that visibility delay has elapsed. The message will automatically appear in the queue after that time. Furthermore Azure Storage Queues does not allow you to fetch a message by message id.

I guess all you can do is list messages in GET mode (essentially dequeue messages), find the matching message's id and then make it invisible again by changing its visibility timeout property.

Hi, if I do that, I suppose that my message will be processed twice in the queue trigger, right ? – Radu Olteanu Mar 03 '20 at 13:31
Managed to implement it with Azure Durable Functions – Radu Olteanu Mar 03 '20 at 16:07
