详细描述

Raw message payload delivered via DataCallback or sent via send_data().

In non-direct observe/record modes the server relays raw serialised bytes plus routing metadata. In direct mode the callback is fed by the local direct subscriber created by ProxyAPI. When sending data, timestamp and seq are caller-defined and forwarded verbatim.
