Code Examples

Quickstart for Standalone Java Application

public class MyApplication{
    public static void main(String[] args) throws Exception {
        Hekate hekate = new HekateBootstrap()
            .withNamespace("my-cluster")
            .withNodeName("my-node")
            .join();
        
        System.out.println("Cluster topology: " + hekate.cluster().topology());
    }
}

Quickstart for Spring Boot Application

@EnableHekate // <-- Enable Hekate integration.
@SpringBootApplication
public class MyApplication {
    @Autowired
    private Hekate hekate;

    public static void main(String[] args) {
        SpringApplication.run(MyApplication.class, args);
    }
    
    @PostConstruct
    public void start(){
        System.out.println("Cluster topology: " + hekate.cluster().topology());
    }
}
