在apache-kafka使用者中处理无限循环

Question

我是kafka的新手我想为我们的play-scala项目实现一个kafka消息管道系统，我创建了一个插入记录的主题，我写了这样的消费者代码，

val recordBatch = new ListBuffer[CountryModel]
  consumer.subscribe(Arrays.asList("session-queue"))
    while (true) {
      val records = consumer.poll(1000)
      val iter = records.iterator()
      while (iter.hasNext()) {
        val record: ConsumerRecord[String, String] = iter.next()
        recordBatch += Json.parse(record.value()).as[CountryModel]
      }
     processData(recordBatch)
     // Thread.sleep(5 * 1000)
    }

but after certain time  the service is stopping, the processor is going to 100% after certain time machine is stopping, how can i handle this infinite loop.

在生产环境中我不能依赖这个循环吧我试着睡了一段时间，但这不是一个优雅的解决方案
