Asynchronous input processing with asynchronous result |
|
|
|
Asynchronous input processing, in which input is stored in a queue table and picked up from there, may be combined with asynchronous results: if a response is needed, the response message is placed in a second queue table and sent when the system is available. This is a variation on asynchronous input processing with synchronous result. It is useful if the responding service must guarantee the delivery of output messages: if an output message cannot be delivered because of an error, the system must retry after a period of time.
