Designing Cassandra Data Models 101

Designing Cassandra Data Models 101

Fundamentals you should know before designing your first Cassandra data models to get blazing fast I/O performance.

Designing data models in Cassandra can be tricky if you are coming from a Relational Databases background. Even though Cassandra tries it best to draw parallels to relational databases when it comes to terminologies, I feel like it becomes more misleading. Of course CQL (Cassandra Query Language) being so similar to SQL doesn’t help either.

Fundamentally, Cassandra (a NoSQL database) and other relational databases (MySQL, PostgreSQL) are very different from each other. Cassandra is not a drop-in replacement of relational databases. You have to design your schema with an entirely different way of thinking.

To get you started with designing Cassandra data models, I will go through some of the fundamentals I picked up when moving to Cassandra from a relational background.
