Documentation

Definition

The communication mode determines how messages are exchanged:

In synchronous communication, a response message is expected from the receiver after a request has been sent. Once the request message has been sent, the sender application execution stops until the response message arrives. In addition to the response message, fault messages can be sent back to the sender.

Asynchronous operations are one-way messages, so there is no response message. A sender application can send multiple messages to a receiver in a bundle and then continue executing the application.

Mappings for asynchronous operations can be carried out in coupled or decoupled mode. Also see Mapping Mode: Coupled vs. Decoupled and Consumer Mapping and Operation Mapping.
