I am learning the Data Modeling course DS 220. There are 3 questions,
Qn 1. Splitting partition for the video table. Can I use user id, as a compound partition key?
Qn 2: videos_by_user. Is the answer to use title, along as partition key?
Qn3: Can we split the table, like user id, video id, comment and user id, video id, thumbnail? Does that work.
Please let me know if my assumptions/answer is wrong? with some explanation
