/**
* Asynchronous client for accessing AmazonSQS.
* All asynchronous calls made using this client are non-blocking. Callers could either
* process the result and handle the exceptions in the worker thread by providing a callback handler
* when making the call, or use the returned Future object to check the result of the call in the calling thread.
* Amazon Simple Queue Service
* Welcome to the Amazon Simple Queue Service API Reference . This
* section describes who should read this guide, how the guide is
* organized, and other resources related to the Amazon Simple Queue
* Service (Amazon SQS).
*
*
* Amazon SQS offers reliable and scalable hosted queues for storing
* messages as they travel between computers. By using Amazon SQS, you
* can move data between distributed components of your applications that
* perform different tasks without losing messages or requiring each
* component to be always available.
*
*
* Helpful Links:

* Current WSDL (2012-11-05)

* Regions and Endpoints

*
*
*
*
* We also provide SDKs that enable you to access Amazon SQS from your
* preferred programming language. The SDKs contain functionality that
* automatically takes care of tasks such as:
*
*
*
*
* - Cryptographically signing your service requests
* - Retrying requests
* - Handling error responses
*

/**

* Changes the visibility timeout of a specified message in a queue to a

* an existing queue to more than a total visibility timeout of 12 hours.
* (For more information visibility timeout, see
* Visibility Timeout
* in the Amazon SQS Developer Guide .)
*
*
* For example, let's say you have a message and its default message
* visibility timeout is 30 minutes. You could call
* ChangeMessageVisiblity with a value of two hours and the
* effective timeout would be two hours and 30 minutes. When that time
* comes near you could again extend the time out by calling

* would be 9 hours and 30 minutes.
*
*
* NOTE: There is a 120,000 limit for the number of inflight
* messages per queue. Messages are inflight after they have been
* received from the queue by a consuming component, but have not yet
* been deleted from the queue. If you reach the 120,000 limit, you will
* receive an OverLimit error message from Amazon SQS. To help avoid
* reaching the limit, you should delete the messages from the queue
* after they have been processed. You can also increase the number of
* queues you use to process the messages.
*
*
* IMPORTANT:If you attempt to set the VisibilityTimeout to an
* amount more than the maximum time left, Amazon SQS returns an error.
* It will not automatically recalculate and increase the timeout to the
* maximum time remaining.
*
*
* IMPORTANT:Unlike with a queue, when you change the visibility
* timeout for a specific message, that timeout value is applied
* immediately but is not saved in memory for that message. If you don't
