This project is to learn data modeling with Apache Cassandra based on log data from my previous project data-modeling-with-postgres. In the file script.ipynb
, I developed three denormalized tables optimized for the following queries:
- Show the artist, song title and song's length in the music app history that was heard during sessionId = 338, and itemInSession = 4
- Show the name of artist, song (sorted by itemInSession) and user (first and last name) for userid = 10, sessionid = 182
- Show user name (first and last) in the music app history who listened to the song 'All Hands Against His Own'
