Asynchronous method dispatch
Mechanism
The servicing of a client request is immediately dispatched to an available thread from a pool of threads and the client is put in a blocking state. Upon the completion of the task, the server is notified by a callback. The server unblocks the client and transmits the response back to the client. In case of thread starvation, clients are blocked waiting for threads to become available.
Rationale
Asynchronous method dispatch (AMD) is a data communication method used when there is a need for the server side to handle a large set of long running client requests. Using Synchronous method dispatch (SMD), this scenario may turn the server into an unvavailable busy state resulting in a connection failure response cased by a network connection request timeout.
