Hi, I'm trying to make a data model for pruchase logs. Since its a log model, there is no unique key. Thus, I cannot write partition, primary key. What should I do for that?
Timestamp timestamp; int item; int amount; int price; UUID seller; UUID buyer;
- Which keys should I put into cluster section?
- Which keys should I put into partition section?
- Is there any problem to have a lot of keys in cluster section?
