Cassandra Module

Usage example

This example connects to the Cassandra Cluster, creates a keyspaces and asserts that is has been created.

public class SomeTest {

    @Rule
    public CassandraContainer cassandra = new CassandraContainer();


    @Test
    public void test(){
        Cluster cluster = cassandra.getCluster();

        try(Session session = cluster.connect()) {

            session.execute("CREATE KEYSPACE IF NOT EXISTS test WITH replication = \n" +
                    "{'class':'SimpleStrategy','replication_factor':'1'};");

            List<KeyspaceMetadata> keyspaces = session.getCluster().getMetadata().getKeyspaces();
            List<KeyspaceMetadata> filteredKeyspaces = keyspaces
                    .stream()
                    .filter(km -> km.getName().equals("test"))
                    .collect(Collectors.toList());

            assertEquals(1, filteredKeyspaces.size());
        }
    }

}
