-<p>Principle: asynchronous transmission refers to the sender sends the data, not the receiver
-back to respond, and then send the next packet communication. Asynchronous send MQ,
-users need to realize asynchronous callback interface (SendCallback), in the implementation
-of asynchronous send message to the application server, without waiting for a response can
-be returned directly to the receiving server, through the callback interface response, and
-response to the server for processing results.</p>

-response time sensitive business scenarios, such as user video upload after notification to
-start transcoding, the transcoding after push notification transcoding results.</p>
