/**
* Client for accessing Amazon SQS. All service calls made using this client are blocking, and will not return until the
* service call completes.
*
*
* 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.
*

*
*
*
* 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 new value. The maximum allowed timeout
* value you can set the value to is 12 hours. This means you can't extend the timeout of a message in 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 5 minutes. After 3
* minutes, you call ChangeMessageVisiblity with a timeout of 10 minutes. At that time, the timeout for
* the message would be extended by 10 minutes beyond the time of the ChangeMessageVisibility call. This results in
* a total visibility timeout of 13 minutes. You can continue to call ChangeMessageVisibility to extend the
* visibility timeout to a maximum of 12 hours. If you try to extend beyond 12 hours, the request will be rejected.
*
*
*
* 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.
*
*
*
* 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.
*
*
*
* 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 delete a message after it is received, the
* visibility timeout for the message the next time it is received reverts to the original timeout value, not the
* value you set with the ChangeMessageVisibility action.
*
*
*
* @param changeMessageVisibilityRequest
* @return Result of the ChangeMessageVisibility operation returned by the service.
* @throws MessageNotInflightException

*
*
* For each message returned, the response includes the following:
*
*
* -
*
* Message body
*
*

*
* The receipt handle is the identifier you must provide when deleting the message. For more information, see Queue
* and Message Identifiers in the Amazon SQS Developer Guide.

*
* You can provide the VisibilityTimeout parameter in your request, which will be applied to the

* timeout for the queue is used for the returned messages. For more information, see Visibility
