Choice PK and SK in DynamoDB

0 votes

I have the following two items which I need to store in dynamodb

  • Artists

  • Songs

The artists have an ID (unique for artists), name and gender. The Songs have an ID (unique for songs), title, genre, artist and rating.

How should I model this in DynamoDB?.

I was thinking about this: ID as the primary key and having a sort key that contains the artist or song so they are distinguished. Is this a good choice? For example, I find I see more variety in the sort key.

What about the field artist in song items? Should I just point to the ID of the artist?
