I read some difference between nosql and sql, and one obvious differences is nosql supporting schemaless.
But I try it in cassandra and get result not like that. Ex: cqlsh:key> Create table if not exists yo (blk bigint primary key, count int); cqlsh:key> insert into yo (blk, count, test) values (2,4,'123'); It shows message="Undefined column name test" So cassandra isn't schemaless?
