Cassandra Data Modeling

So, you want to create a Cassandra schema? Cassandra's schema development methodology is different from the relational world's approach.

So, you want to create a Cassandra schema? Cassandra's schema development methodology is different from the relational world's approach.

In this scenario, we'll learn how to create a Cassandra schema that deals with:

How to create tables
How to handle table joins
How to handle queries on non-primary key columns

If you are coming from a relational world, you create a schema by thinking about your data, creating a normalized model and then figuring out how to use the model in your app. Cassandra reverses this process by having you focus on queries within the app and using those queries to drive table design. We'll show you how!
