Learn about Apache Cassandra and its key scalable and reliable data management features.

cassandra.tar.gz

Apache Cassandra is an open-source, distributed NoSQL database recognized for its scalability, reliability, and continuous availability. The course explores the core concepts that drive these features, including distributed architecture, data modeling, CQL, table design, data types, tunable consistency, and the read/write path. 

Lessons combine theoretical insights with hands-on exercises, allowing you to execute CQL queries directly in your browser and view real-time results with no setup required. Additionally, each module concludes with a quiz to test your understanding of the material. 

By the end of this course, you’ll be equipped with the skills needed to use Cassandra for high-performance data management.
