SpringKafka总是重新平衡后5分钟，即使我暂停消费

有一个耗时的操作（约10分钟），但Kafkaaways重新平衡后5分钟，甚至我暂停消费者。消费者方法：

@KafkaListener(topics = {TopicAppoint.EXECUTE_SCHOOL_DATA_STATICS_TASK})
public void receiveMessage(@Payload String payload, Consumer<String, String> consumer) {

    Set<TopicPartition> assignment = consumer.assignment();
    consumer.pause(assignment);

    if (StringUtils.isNotEmpty(payload)) {
        SchoolStatisticsTaskDTO staticsTaskDTO = JSONObject.parseObject(payload, SchoolStatisticsTaskDTO.class);
        Optional<SchoolStatisticsTaskDO> taskOptional = schoolStatisticsTaskRepository.findById(staticsTaskDTO.getTrackId());
        taskOptional.ifPresent(schoolStaticsTaskDO -> {
            // handler
        });
    }

    consumer.resume(assignment);
}

这是我的配置：

kafka:
bootstrap-servers: 192.168.0.230:9092
producer:
  key-serializer: org.apache.kafka.common.serialization.StringSerializer
  value-serializer: org.apache.kafka.common.serialization.StringSerializer

  properties:
    max.request.size: 12582912
consumer:
  key-deserializer: org.apache.kafka.common.serialization.StringDeserializer
  value-deserializer: org.apache.kafka.common.serialization.StringDeserializer
  group-id: dc-fitness-data-consumer-group
  properties:
    max.partition.fetch.bytes: 12582912
  #enable-auto-commit: false

让我们先看一下文档 pause() 方法
在此处暂停公共void（集合分区）
暂停从请求的分区获取。在使用resume（collection）恢复这些分区之前，将来对poll（long）的调用不会返回这些分区中的任何记录。请注意，此方法不影响分区订阅。特别是，当使用自动分配时，它不会导致组重新平衡。
从上面的描述来看 pause() 方法将暂停分区获取消息，但不会暂停使用者线程，这意味着使用者线程将执行后续操作 poll() 请求暂停分区，但不会获取任何记录
在您的应用程序中：分区被暂停，但使用者线程忙于执行耗时的操作超过10分钟，而没有执行任何轮询请求。
检测使用者失败：因此当轮询停止时，心跳将不会发送到集群
订阅一组主题后，当调用poll（long）时，使用者将自动加入组。pollapi旨在确保消费者的活跃性。只要您继续调用poll，使用者将留在组中，并继续从分配给它的分区接收消息。在底层，poll api定期向服务器发送心跳信号；当您停止调用poll（可能是因为抛出了异常）时，将不会发送心跳。如果在服务器接收到心跳信号之前经过了一段配置的会话超时时间，则使用者将被踢出组，并且其分区将被重新分配。
解决方案：增加以下属性的超时，因为默认时间是每5分钟重新平衡一次（个人不支持增加超时）
新的java使用者现在支持后台线程的心跳。有一个新的配置 max.poll.interval.ms 它控制在使用者主动离开组之前轮询调用之间的最长时间（默认为5分钟）。配置的值 request.timeout.ms 必须始终大于max.poll.interval.ms，因为这是使用者重新平衡时joingroup请求可以在服务器上阻止的最长时间，所以我们将其默认值更改为略高于5分钟。最后，session.timeout.ms的默认值被调整为10秒，而 max.poll.records 已更改为500。
解决方案2：如果您需要用更少的时间处理大量数据，那么增加更多的分区并使用每个线程的每个分区（这意味着更多的并发性），减少5分钟内可以处理的数据
