        public SequentialWriter asSequentialWriter()
        Returns SequentialWriter associated with this writer. Convenient when interacting with Cassandra codebase to write files to disk. Note that all bytes written to the returned writer will still contribute to the checksum.
        Returns:
        SequentialWriter associated with this writer
