Tuples
A tuple is a fixed-length list, where values can be of different types.
To define a tuple data type,
Cassandra Query Language provides construct TUPLE<type1,type2,..., typeN>,
where type1 , type2 , ... , typeN can refer to same or different CQL data types, including
INT, DATE, UUID and so forth.
✅ Here is an example of a TUPLE column:
ALTER TABLE users ADD full_name TUPLE<TEXT,TEXT,TEXT>;
UPDATE users
SET full_name = ('Joe', 'The', 'Great')
WHERE id = 7902a572-e7dc-4428-b056-0571af415df3;
SELECT name, full_name FROM users;
Unlike UDTs, individual tuple components cannot be updated without updating the whole tuple. Therefore, you should always prefer UDTs to tuples.
