Cassandra is a distributed database from Apache that is highly scalable and designed to manage very large amounts of structured data. It provides high availability with no single point of failure.

The app starts off with a basic introduction of Cassandra followed by its architecture, installation, and important classes and interfaces. Thereafter, it proceeds to cover how to perform operations such as create, alter, update, and delete on keyspaces, tables, and indexes using CQLSH as well as Java API. The app also has dedicated chapters to explain the data types and collections available in CQL and how to make use of user-defined data types.

This app will be extremely useful for software professionals in particular who aspire to learn the ropes of Cassandra and implement it in practice.

It is an elementary app and you can easily understand the concepts explained here with a basic knowledge of Java programming. However, it will help if you have some prior exposure to database concepts and any of the Linux flavors.
