Aws::SQS::QueuePoller automatically call change_message_visibility_timeout while work is in progress

[michaelwittig]

Is your feature request related to a problem? Please describe.
I use the Aws::SQS::QueuePoller to get messages from SQS. I can either define an :visibility_timeout or the queue's default value is used. I can also call poller.change_message_visibility_timeout(msg, 60) to add another timeout if I need more time. But in situations where the processing is an expensive blocking call, I can not easily do that (e.g., download a large file from S3).

Describe the solution you'd like
So I was asking myself, why can't the poller automatically call change_message_visibility_timeout every x seconds to reset the timeout x+y while the work is in progress (code has neither returned or thrown).

Describe alternatives you've considered
One idea I had is to start a Thread inside the block that calls the change_message_visibility_timeout from time to time until I kill it when I reached the end of my code block.

I would be willing to look into this @mullermp. Are there any issues with adding functionality to these generated files?

[mullermp]

Thanks for reaching out about this. QueuePoller is not code generated, so you are free to change the file. As far as the feature request goes, on the surface, having a managed thread that updates the timeout until the block has returned might be ok, but it definitely needs to be an opt-in feature. I don't like the possibility that the poller could be blocked infinitely with no timeout - we still should configure a maximum. AFAIK the maximum visibility timeout is already 12 hours - are there really s3 downloads that take that long? I am doubting the need for this feature request. @JohnLegrandRichards are you by chance running into an issue in your application that requires this feature?

[mullermp]

I am closing this because 12 hours is an extremely generous maximum visibility timeout. We will re-consider with more customer data.

@mullermp the point is not that something takes longer than 12 hours.

The point is that you can consistently tell SQS that the message is still worked on. In case a worker dies, the messages is quickly picked up by another worker. Instead of waiting for the 12 hours to end (or whatever the visibility timeout was).

[mullermp]

That makes sense, sorry, I will re-open this.
