Message Relay is a Message Pass through mechanism for ESB. Message Relay enables ESB to pass the messages without building or processing the message.
When Message Relay is configured incoming requests to the ESB are not built and processed unless specifically requested to do so. An incoming message is wrapped inside a default SOAP envelope as binary content and sent through the ESB.
Some of the ESB scenarios don not require the full message to be built. Instead ESB can work on other message properties like request URLs or transport headers (for more information about properties and headers see ).
With Message Relay ESB can achieve a very high throughput.
