Create a Cassandra service on Aiven, you can either use the console, the CLI or Terraform.

Once the service is running, use the Quick Connect button and connect to your service using csqlsh.

Once connected create the keyspace :

CREATE KEYSPACE aiven_keyspace
        WITH REPLICATION = { 
          'class' : 'SimpleStrategy', 
          'replication_factor' : 2 
      };

You need to create a Java Trustore based on the CA. Download the CA file from the Aiven console and then run :

keytool -import  \               
  -file ca.pem   \
  -alias CA      \
  -keystore client.truststore.jks

You will be prompted to enter a password, choose whatever you want and remember it because you will need it in the application.properties. Copy client.truststore.jks in src/main/resources.

Open src/main/resources/application.properties and replace all the placeholders delimited with <>.

You're ready to run the app : mvn spring-boot:run
