The
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.
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 once, the ReceiptHandle
is different
each time you receive a message. When you use the DeleteMessage
action, you
must provide the most recently received ReceiptHandle
for the message (otherwise,
the request succeeds, but the message will not be deleted).
This is an asynchronous operation using the standard naming convention for .NET 4.5 or higher. For .NET 3.5 the operation is implemented as a pair of methods using the standard naming convention of BeginDeleteMessage and EndDeleteMessage.
