Deletes the specified message from the specified queue. To select the message to
delete, use the
ReceiptHandle of the message (not the
MessageId which you receive when you send the message). Amazon SQS can
delete a message from a queue even if a visibility timeout setting causes the message to
be locked by another consumer. Amazon SQS automatically deletes messages left in a queue
longer than the retention period configured for the queue.
ReceiptHandle is associated with a specific
instance of receiving a message. If you receive a message more than
ReceiptHandle is different each time you receive a message.
When you use the
DeleteMessage action, you must provide the most
ReceiptHandle for the message (otherwise, the request
succeeds, but the message might not be deleted).
For standard queues, it is possible to receive a message even after you delete it. This might happen on rare occasions if one of the servers which stores a copy of the message is unavailable when you send the request to delete the message. The copy remains on the server and might be returned to you during a subsequent receive request. You should ensure that your application is idempotent, so that receiving a message more than once does not cause issues.
