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.

Adds a permission to a queue for a specific principal.
This allows for sharing access to the queue.

ChangeMessageVisibility(string, string, int) |
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 30 minutes. You could call 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. 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.ChangeMessageVisibility action. |

action.

CreateQueue(string) |
Creates a new queue, or returns the URL of an existing one. When you request CreateQueue ,
you provide a name for the queue. To successfully create a new queue, you must provide
a name that is unique within the scope of your own queues.
If you delete a queue, you must wait at least 60 seconds before creating a queue with the same name. You may pass one or more attributes in the request. If you do not provide a value for any attribute, the queue will have the default value for that attribute. Permitted attributes are the same that can be set using SetQueueAttributes.
Use GetQueueUrl to get a queue's URL. GetQueueUrl requires only the

DeleteMessage(string, string) |
Deletes the specified message from the specified queue. You specify the message by
using the message's receipt handle and not the message ID
you received when you sent the message. Even if the message is locked by another reader
due to the visibility timeout setting, it is still deleted from the queue. If you
leave a message in the queue for longer than the queue's configured retention period,
Amazon SQS automatically deletes it.
The receipt handle is associated with a specific instance of receiving the message.
If you receive a message more than once, the receipt handle you get each time you
receive the message is different. When you request It is possible you will receive a message even after you have deleted it. This might happen on rare occasions if one of the servers storing a copy of the message is unavailable when you request to delete the message. The copy remains on the server and might be returned to you again on a subsequent receive request. You should create your system to be idempotent so that receiving a particular message more than once is not a problem. |

DeleteMessageBatch(string, List<DeleteMessageBatchRequestEntry>) |
Deletes up to ten messages from the specified queue. This is a batch version of DeleteMessage.
The result of the delete action on each message is reported individually in the response.
Because the batch request can result in a combination of successful and unsuccessful actions, you should check for batch errors even when the call returns an HTTP status code of 200. param.n notation. Values of n are integers starting

|
DeleteQueue(string) |
Deletes the queue specified by the queue URL, regardless of whether the queue
is empty. If the specified queue does not exist, Amazon SQS returns a successful response.
Use When you delete a queue, the deletion process takes up to 60 seconds. Requests you send involving that queue during the 60 seconds might succeed. For example, a SendMessage request might succeed, but after the 60 seconds, the queue and that message you sent no longer exist. Also, when you delete a queue, you must wait at least 60 seconds before creating a queue with the same name. We reserve the right to delete queues that have had no activity for more than 30 days.
