Because in this example we suppose that the first record maps a subscribed item. So, each change in this record is pushed to the clients. In real-world scenarios, you could have different mappings.

The Lightstreamer Server will take care of sending the clients only the changed values. So if no fields have changed, the Server will automatically avoid sending messages to the clients.
