                reaches the max number of rows it calls finish_batch() to
                mutate the current row batch. Default is FLUSH_COUNT (1000
                rows).

        :type max_row_bytes: int
        :param max_row_bytes: (Optional) Max number of row mutations size to
                flush. If it reaches the max number of row mutations size it
                calls finish_batch() to mutate the current row batch.
                Default is MAX_ROW_BYTES (5 MB).
