We started from Chapter 1, Bird's Eye View of Cassandra, to review the basics of Cassandra. We then touched on the important facets of data modeling in Cassandra, such as Modeling by query technique, the wealthy set of data types, and the indexes. These techniques and knowledge are put together into an example data analysis application in the stock trading domain called Stock Screener Application. We walked through and explained every single detail of the application, although at a fast pace. We also illustrated how to enhance the first-cut version with changes on the data model and coding to demonstrate the great flexibility provided by Cassandra. We then turned to plan and migrate the enhanced system to a production-ready cluster with considerations on the replication strategy, snitch, replication factor, the basic monitoring and performance tuning tools.
I really enjoyed writing this book for you and I sincerely hope that it is as useful for you when it comes to rapidly using Cassandra in real-world projects, as it has been fun for me. Your comments are always welcomed and you can contact me through Packt Publishing.
