/**
 * Interface for accessing Amazon SQS.
 * <p>
 * <b>Note:</b> Do not directly implement this interface, new methods are added to it regularly. Extend from
 * {@link com.amazonaws.services.sqs.AbstractAmazonSQS} instead.
 * </p>
 * <p>
 * <p>
 * Welcome to the <i>Amazon Simple Queue Service API Reference</i>.
 * </p>
 * <p>
 * Amazon Simple Queue Service (Amazon SQS) is a reliable, highly-scalable hosted queue for storing messages as they
 * travel between applications or microservices. Amazon SQS moves data between distributed application components and
 * helps you decouple these components.
 * </p>
 * <p>
 * You can use <a href="http://aws.amazon.com/tools/#sdk">AWS SDKs</a> to access Amazon SQS using your favorite
 * programming language. The SDKs perform tasks such as the following automatically:
 * </p>
 * <ul>
 * <li>
 * <p>
 * Cryptographically sign your service requests
 * </p>
 * </li>
 * <li>
 * <p>
 * Retry requests
 * </p>
 * </li>
 * <li>
 * <p>
 * Handle error responses
 * </p>
 * </li>
 * </ul>

     * Changes the visibility timeout of a specified message in a queue to a new value. The default visibility timeout

     * Visibility Timeout</a> in the <i>Amazon Simple Queue Service Developer Guide</i>.
     * </p>
     * <p>
     * For example, you have a message with a visibility timeout of 5 minutes. After 3 minutes, you call
     * <code>ChangeMessageVisibility</code> with a timeout of 10 minutes. You can continue to call
     * <code>ChangeMessageVisibility</code> to extend the visibility timeout to the maximum allowed time. If you try to
     * extend the visibility timeout beyond the maximum, your request is rejected.
     * </p>
     * <p>
     * An Amazon SQS message has three basic states:
     * </p>
     * <ol>
     * <li>
     * <p>
     * Sent to a queue by a producer.
     * </p>
     * </li>
     * <li>
     * <p>
     * Received from the queue by a consumer.
     * </p>
     * </li>
     * <li>
     * <p>
     * Deleted from the queue.
     * </p>
     * </li>
     * </ol>
     * <p>
     * A message is considered to be <i>stored</i> after it is sent to a queue by a producer, but not yet received from
     * the queue by a consumer (that is, between states 1 and 2). There is no limit to the number of stored messages. A
     * message is considered to be <i>in flight</i> after it is received from a queue by a consumer, but not yet deleted
     * from the queue (that is, between states 2 and 3). There is a limit to the number of inflight messages.
     * </p>
     * <p>
     * Limits that apply to inflight messages are unrelated to the <i>unlimited</i> number of stored messages.
     * </p>
     * <p>
     * For most standard queues (depending on queue traffic and message backlog), there can be a maximum of
     * approximately 120,000 inflight messages (received from a queue by a consumer, but not yet deleted from the
     * queue). If you reach this limit, Amazon SQS returns the <code>OverLimit</code> error message. To avoid reaching
     * the limit, you should delete messages from the queue after they're processed. You can also increase the number of
     * queues you use to process your messages. To request a limit increase, <a href=
     * "https://console.aws.amazon.com/support/home#/case/create?issueType=service-limit-increase&amp;limitType=service-code-sqs"
     * >file a support request</a>.
     * </p>
     * <p>
     * For FIFO queues, there can be a maximum of 20,000 inflight messages (received from a queue by a consumer, but not
     * yet deleted from the queue). If you reach this limit, Amazon SQS returns no error messages.
     * </p>
     * <important>
     * <p>
     * If you attempt to set the <code>VisibilityTimeout</code> to a value greater than the maximum time left, Amazon
     * SQS returns an error. Amazon SQS doesn't automatically recalculate and increase the timeout to the maximum
     * remaining time.
     * </p>
     * <p>
     * Unlike with a queue, when you change the visibility timeout for a specific message the timeout value is applied
     * immediately but isn't saved in memory for that message. If you don't delete a message after it is received, the
     * visibility timeout for the message reverts to the original timeout value (not to the value you set using the
     * <code>ChangeMessageVisibility</code> action) the next time the message is received.
