I'm not completely sure what the latest Thrift behavior around this is (it's never been great), but this is one of the things that cql3 is designed to solve well. I would consider using cql3 if that's an option for you.

Hi All,I am trying to design my schema using composite column. One thing I am a bit confused is how to define validation_class for the composite column, or is there a way to define it?for the composite column, I might insert different value based on the column name, for exampleI will insert date for column "created":set user['7:1:100:created'] = 1351728000;and insert String for descriptionset user['7:1:100:desc'] = my description;I don't see a way to define validation_class for composite column. Am I right?Thanks.-Wei
