* SQS Long Polling</a> in the <i>Amazon Simple Queue Service Developer Guide</i>.
* </p>
* <p>
* Short poll is the default behavior where a weighted random set of machines is sampled on a
* <code>ReceiveMessage</code> call. Thus, only the messages on the sampled machines are returned. If the number of
* messages in the queue is small (fewer than 1,000), you most likely get fewer messages than you requested per
* <code>ReceiveMessage</code> call. If the number of messages in the queue is extremely small, you might not
* receive any messages in a particular <code>ReceiveMessage</code> response. If this happens, repeat the request.
* </p>
* <p>
* For each message returned, the response includes the following:
* </p>
* <ul>
* <li>
* <p>
* The message body.
* </p>
* </li>
* <li>
* <p>
* An MD5 digest of the message body. For information about MD5, see <a
* href="https://www.ietf.org/rfc/rfc1321.txt">RFC1321</a>.
* </p>
* </li>
* <li>
* <p>
* The <code>MessageId</code> you received when you sent the message to the queue.
* </p>
* </li>
* <li>
* <p>
* The receipt handle.
* </p>
* </li>
* <li>
* <p>
* The message attributes.
* </p>
* </li>
* <li>
* <p>
* An MD5 digest of the message attributes.
* </p>
* </li>
* </ul>
* <p>
* The receipt handle is the identifier you must provide when deleting the message. For more information, see <a
* href
* ="https://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/sqs-queue-message-identifiers.html"
* >Queue and Message Identifiers</a> in the <i>Amazon Simple Queue Service Developer Guide</i>.
* </p>
* <p>
* You can provide the <code>VisibilityTimeout</code> parameter in your request. The parameter is applied to the
* messages that Amazon SQS returns in the response. If you don't include the parameter, the overall visibility
* timeout for the queue is used for the returned messages. For more information, see <a
* href="https://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/sqs-visibility-timeout.html"
* >Visibility Timeout</a> in the <i>Amazon Simple Queue Service Developer Guide</i>.

* href="https://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/sqs-visibility-timeout.html">
* 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&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.
