Message Relay enables the ESB profile of WSO2 Enterprise Integrator (WSO2 EI) to pass messages along without building or processing them unless specifically requested to do so. When Message Relay is enabled, an incoming message is wrapped inside a default SOAP envelope as binary content and sent through the ESB. This is useful for scenarios where the ESB does not need to work on the full message but can work on message properties like request URLs or transport headers instead. With Message Relay, the ESB can achieve a very high throughput.
