Azure function: set infinite TTL when adding a message to a queue

Question

Hi,

I've created an Azure Function having an HTTP trigger and an Azure Queue Storage as output.

The function simply add a new message to the Queue.

It's possible to set the Expiration Time TTL to infinite (-1) when the message is added to the queue?

I've followed the procedure described in this link: en-us/azure/azure-functions/functions-integrate-storage-queue-output-binding?tabs=csharp but I cannot see how to specify the Expiration time.

Thanks

Hi @Fabio

You need to update the output binding. For C# you can use the CloudQueue as per the below code.
To set up the TTL as infinite you need to use the overloaded method and set timeToLive parameter to maximum value i.e. TimeSpan.MaxValue. Other parameters you can set according to your business needs.
Reference: https://video2.skills-academy.com/en-us/azure/azure-functions/functions-bindings-storage-queue-output?tabs=csharp#usage

        public static async Task QueueOutputAsync([HttpTrigger] HttpRequest input, [Queue("")] CloudQueue outputQueue)  
        {  
            await outputQueue.AddMessageAsync(new CloudQueueMessage(""),TimeSpan.MaxValue,TimeSpan.FromSeconds(0),new QueueRequestOptions(),new OperationContext());  
        }
