How to keep/prevent a message from being deleted/consumed

[talbananaz]

Summary

I would like to know how to keep/prevent a message from being deleted/consumed?
I want one machine to just read what is going on (without deleting the message) and another to consume the message.
I have a dead letter queue set up so if I return an empty object or throw it ends up there and that is not the behaviour that I want.

Example

There's a setting for this: https://bbc.github.io/sqs-consumer/interfaces/ConsumerOptions.html#shouldDeleteMessages
