Spring Kafka再平衡澄清

我只想了解Kafka的再平衡。这是我的听众方法。我已将retrytemplate与consumer factory配置为重试20次，回退延迟为20秒。我使用的是SpringKafka1.2.2（我们计划升级客户端）和手动确认。

@KafkaListener(id = "${kafka.listener-id}", topics = "${kafka.topic}")
public void listen(final ConsumerRecord<String, String> consumerRecord,
                   final Acknowledgment acknowledgment) throws ServiceResponseException {}

    if (true){
        System.out.println("throwing exception ");
        throw new RuntimeException();
    }

    try {
        acknowledgment.acknowledge();
        LOGGER.info("Kafka acknowledgment sent for Transaction ID:");
    } catch (Exception e) {
        LOGGER.info("Exception encountered when acking record with transaction id: {}");
    } 
}

我有2个工人，每个人有2个并发性。在Kafka我有三个分区。我启动了一个worker，并为worker1分配了3个分区。然后我发了一条信息。在侦听器中抛出runtimeexception，这种情况会发生20次，延迟20秒。当我启动worker2时，kafka重新平衡触发器，但分区还没有分配。worker1失败，并显示消息“error while processing:consumerrecord”（在getcontainerproperties（）.getshutdowntimeout（）之后），然后所有使用者都加入该组。现在同样的消息被传递到worker2。
1） 这正是我所需要的。但我有一个问题，当重新平衡触发时，为什么分区分配没有立即发生，而是等待worker1完全停止（等待getcontainerproperties（）.getshutdowntimeout（）），然后来自worker1和worker2的所有使用者加入组。
2） 在重新平衡的过程中，我观察到消费者不再进行民意调查（从下面的日志）。是真的吗？

1.3之前的版本有一个非常复杂的线程模型，以避免由于侦听器速度慢而重新平衡。kip-62使我们能够在1.3及更高版本中使用更简单的线程模型。
1.2.x不再受支持，我也没有时间（或倾向于）回去弄清楚发生了什么。请升级到1.3.7（或更好的2.1.10）。
