     * - The `updateStart` method should be called to start an update batch before writing buffered messages.
     * - The `updateEnd` method should be called to signify the end of an update batch after messages are written.
     * - Unbuffered messages should NOT be written AFTER buffered messages within an update batch.
     * - Unbuffered messages may be written outside of an update batch.
