Katacoda scenarios now available on O’Reilly Learning site
It’s been almost 4 months since the release of Cassandra: The Definitive Guide, 3rd edition. The response to the book has been great and I’m really grateful to my employer, DataStax, for sponsoring the book and making a digital copy available for free.
I’m writing to share about a new companion project I’ve had the chance to create. If you’ve read the book, you’ve seen that it contains quite a few code samples in CQL, Java, and more. It’s always been my desire to make it simple for readers to leverage these code samples without having to type out each individual command. To this end, for the 2nd edition of the book, I put together some scripts and made them available on GitHub, but for the 3rd edition there’s an exciting new option available — Katacoda. Here’s an example of what these scenarios look like:
In all, there are 17 different scenarios that I’ve developed for the O’Reilly Learning site, grouped into four short courses:
- Getting Started with Cassandra — this string is based on Chapter 3, Installing Cassandra, and Chapter 4, The Cassandra Query Language
- Data Modeling with Cassandra — This string is based on Chapter 5, Cassandra Data Modeling, and also brings in some of the advanced topics from Chapter 7, Application Development with Cassandra
- Application Development with DataStax Java Driver — This string is based on Chapter 8, Application Development with Drivers
- Apache Cassandra Integrations — This string is based on Chapter 15, Migrating and Integrating
The development process
Writing the scenarios was a fun experience, as I really enjoyed the process of creating “learning as code”, carrying on the same toolset and process I shared about previously in my post Books as Code.
How to find the scenarios
The quickest way to access these scenarios within the site is to use this playlist that walks you through the flow of the chapters and scenarios mentioned above.
While the site does require a subscription, I’m happy to share that O’Reilly has made it possible for users to get a 30-day free trial that will allow you to experience these Cassandra scenarios and a wealth of other content that you’ll want to try out.

Personally I’ve found learning.oreilly.com to be a super valuable collection of resources that I’ve made frequent use of in my day job, and as an O’Reilly author. As an example, check out this playlist on NoSQL Databases that I helped curate.
Upcoming hands-on workshops
I should also note that I’ll be making use of the Katacoda scenarios in two upcoming workshops on O’Reilly Learning:
Building Applications with Apache Cassandra (Sept 9)— I’ve been doing this course for about three years but have now had the opportunity to rework it so that we use Katacoda scenarios for course exercises.
