C* Keys: Partitioning, Clustering, & CrossFit (Adam Hutson, DataScale) | Cassandra Summit 2016

Slides: https://www.slideshare.net/DataStax/c... | Primary and Clustering Keys should be one of the very first things you learn about when modeling Cassandra data. Most people coming from a relational background automatically think, ""Yeah, I know what a Primary Key is"", and gloss right over it. Because of this, there always seems to be a lot of confusion around the topic of Primary Keys in Cassandra. This presentation will demystify that confusion. I will cover what the different types of Keys are, how they can be used, what their purpose is, and how they affect your queries.

For this presentation, I will be using CrossFit gym locations as my subject matter. I will explain the differences between Primary Keys, Compound Keys, Clustering Keys, & Composite Keys. I will also show how the data behind each type differs as stored on disk. Lastly, I will show what queries each type of key will support.
