      • NAME_LENGTH

        public static final int NAME_LENGTH
        longest permissible KS or CF name. Our main concern is that filename not be more than 255 characters; the filename will contain both the KS and CF names. Since non-schema-name components only take up ~64 characters, we could allow longer names than this, but on Windows, the entire path should be not greater than 255 characters, so a lower limit here helps avoid problems. See CASSANDRA-4110.
