• Cassandra instance
• a bootstrap creator for the tables and keyspaces
• the Springboot Application

What the example contains

• Cassandra Bootstrap A Cassandra bootstrap command to create the keyspace and table in Cassandra so they are present when the Springboot Application starts up. This is standalone only requires the cql files that need to be applied.

• Springboot Application This application contains a basic Springboot Application that uses org.springframework.boot:spring-boot-starter-data-cassandra to use the table within the applicaiotn. This gives us annotations such as :

  • @Repository which exposes some basic lookups immediately. Explained in more detail - https://docs.spring.io/spring-data/cassandra/docs/current/reference/html/#repositories.core-concepts
