    private AtomicInteger atomicInteger = new AtomicInteger(0);

    @Autowired
    private ReactiveRedisTemplate<String, String> redisTemplate;

    @Override
    @SneakyThrows
    public void onMessage(ObjectRecord<String, Product> record) {
        System.out.println(
                InetAddress.getLocalHost().getHostName() + " - consumed :" +
                record.getValue()

        this.redisTemplate
                .opsForZSet()

                .subscribe();
        atomicInteger.incrementAndGet();
    }

    @Scheduled(fixedRate = 10000)

                "Total Consumed :: " + atomicInteger.get()
