AWS SQS NACK doing nothing?

[spc16670]

When nacking SQS message I would expect it to the immediately returned back to the broker i.e. NACKing should set the VisibilityTimeout to 0. Current implementation does not seem to do anything.

https://github.com/smallrye/smallrye-reactive-messaging/blob/4.21.0/smallrye-reactive-messaging-aws-sqs/src/main/java/io/smallrye/reactive/messaging/aws/sqs/SqsMessage.java#L120

Also is there a way to manually extend the message's VisibilityTimeout in case it is about to expire when the processing takes longer than expected?

Thank you for your feedback, the SQS connector is still in preview and if you are willing to contribute I can help to get in a configurable failure handler to change the message visibility of the nacked message.

@ozangunalp am kind of thinking to contribute on this. Can you please give me some directions

@prakashelango that's great news!

You can do like the ack handler already existing on the SqsMessage, to add a failure handler. A first implementation for that failure handler would do nothing (current strategy) and a second implementation would do a call using the consumer client to send a request to set message visibility to 0 using the message id.

The connector channel can receive an attribute to choose between two strategies.

There are some other examples on other connectors. You can also check those.
