import java.util.concurrent.TimeUnit;


public class TaskScheduler {

    private static ScheduledExecutorService scheduledExecutor = Executors.newScheduledThreadPool(5);

    /**
     * @param args
     */
    public static void main(String[] args) {

        MetadataTask humanTask = new MetadataTask(Metadata2KafkaTask.TARGET_TYPE_HUMAN);

        scheduledExecutor.scheduleAtFixedRate(humanTask, 0, 1000, TimeUnit.MILLISECONDS);
