How can we stop spring boot data cassandra from connecting to localhost?

We are using Spring data - cassandra and when we run the application without providing configuration, spring boot tries to connect to localhost. Is there a way to stop spring boot from auto connecting?

Thanks in advance :)

You have multiple ways to achieve that but none of them is just a boolean flag:

  1. Remove the Cassandra dependency, if you can afford dependency exclusion

  2. Provide @Lazy Session/CassandraTemplate @Bean's yourself: 

    @Configuration
public class MyCassandraConfiguration extends CassandraDataAutoConfiguration {

    public MyCassandraConfiguration(BeanFactory beanFactory, CassandraProperties properties, Cluster cluster, Environment environment) {
        super(beanFactory, properties, cluster, environment);
    }

    @Override
    @Bean
    @Lazy
    public CassandraSessionFactoryBean session(CassandraConverter converter) throws Exception {
        return super.session(converter);
    }

    @Bean
    @Lazy
    @Override
    public CassandraTemplate cassandraTemplate(Session session, CassandraConverter converter) throws Exception {
        return super.cassandraTemplate(session, converter);
    }
}

    Lazy beans are initialized the first time they are used.

  3. Exclude the CassandraAutoConfiguration. Depending on your setup even more auto-configurations. This approach is rather invasive as required dependencies might get not initialized.
