6 Step Guide to Apache Cassandra Data Modelling

Whitepapers

Download

This white paper sets out a methodical approach that we have found useful in approaching Cassandra data modelling. Our approach focuses on 3 simple principles: understand the data, define the entities and then review and tune.

We have defined a set of distinct steps that implement these principles:

  • Step 1: Define the data domain
  • Step 2: Define the required access patterns
  • Step 3: Identify the primary access entities
  • Step 4: Allocate secondary entities
  • Step 5: Review partition and cluster keys
  • Step 6: Test and tune

As well as defining the process in this paper, we provide a worked example based on building a database to store and retrieve log messages from multiple servers.
