I want to make unique constraint in cassandra . As i want that all the value in my column be unique in my column family ex: name-rahul phone-123 address-abc
now i want that in this row no values equal to rahul ,123 and abc get inserted again on searching on datastax i found that i can achieve it by doing query on partition key as IF NOT EXIST ,but not getting the solution for getting all the three values unique means if name- jacob phone-123 address-qwe this should also be not inserted into my database as my phone column has the same value as i have shown with name-rahul.
