     * SW_PROTOCOL_MESSAGE
     * ==================================================================
     * When sending the `EventData` structure, the message can be split into multiple transmissions.
     * When sending data in multiple parts, you must set a unique `info.msg_id`.
     * For the first slice, set the `info.flags` with the SW_EVENT_DATA_CHUNK | SW_EVENT_DATA_BEGIN flag,
     * and for the last slice, set the `info.flags` with the SW_EVENT_DATA_CHUNK | SW_EVENT_DATA_END flag.
     * The receiving end will place the data into a memory cache table, merge the data,
     * and only execute the onMessage callback once the complete message has been received.
     *
     * Reference: MessageBus::write() and MessageBus::read()
     *
     * SW_PROTOCOL_STREAM

     *  +-------------------------------- - - - - - - - - - - - - - - - +
     *
     *  The packet consists of a 4 byte length header followed by the data payload.
     *  The receiving end should first use `socket.recv(&payload_len, 4)` to obtain the length of the data payload.
     *  Then, execute `socket.recv(payload, payload_len)` to receive the complete data.
     *  Please note that sufficient memory space must be allocated for the payload,
