If you supply metadata cassandra can use it for several things. 1) It validates data on insertion 2) Helps display the information in human readable formats in tools like the CLI and sstabletojson 3) If you add a built-in secondary index the type information is needed, strings sort differently then integer 4) columns in rows are sorted by the column name, strings sort differently then integers
