Notification Payloads
Apress eBooks · 2006
Event notifications are the lifeblood of an event-based system, so it is very important to choose the right type of delivery mechanism and payload. When notifications cross process boundaries, you have to be really careful about what kind of information is in the payload, because expensive marshaling might be involved. A common solution is to make use of lightweight business objects in notification payloads. These lightweight objects are sculpted carefully to exclude references to unnecessary user-defined types. Such lightweight objects can be passed across process boundaries with a minimum of overhead.
