This module is a very lightweight implementation of the Amazon Simple Queue System.
It supports all the Drupal Queue parameters and uses a library to take the heavy weight away from the module. For now you will need to use a fork of the module and a dev version of the library.
If you want to replace all Drupal queue systems with the amazon queue you can check the checkbox in the admin page but this is not required.
See code snippet below on how to use this module
<?php
// initialize the queue
$queue = new awsSqsQueue('aws_test', 'us-east-2');
// Create the queue
$queue->createQueue();
// Get some data
$item = array('test', '1', '2', '3');
// Add the data to the queue
