问题：

Spring Kafka消费者与2.3.13.RELEASE和2.8.3版本之间的不兼容

卓瀚
2023-03-14

我在使用不同版本的 Spring-kafka 的应用程序的 kafka 使用者方面遇到了问题，特别是在 2.3.13.RELEASE 和 2.8.3 之间。

当使用蓝色/绿色策略部署到PRO时，我遇到的问题是，当在使用者上使用并发时，所有分区都被分配给使用版本2.3.13.RELEASE的应用程序，而在完成分区重新平衡时，使用Spring kafka版本2.8.3（同一主题和组名）部署使用者的新应用程序根本没有分区。

这是当前用于消费者的配置：

    @KafkaListener(topics = "spring.kafka.test", groupId = "group-spring-kafka", concurrency = "10")
    public void processMessage(String content) {
        System.out.println("Message received: " + content);
    }

主题有10个分区。

以下是步骤中的应用程序日志：

可以看出，APP2 的日志（这是带有 spring-kafka 2.8.3 的版本）没有分配分区，而 APP1 保留在 10 个分配的分区中。

我已经尝试以相反的顺序部署，结果是一样的。

如果我部署具有相同版本的应用程序，则结果是正确的，每个应用程序分布 5 个分区。

我还尝试使用“RangeAsSignor”强制两个版本的分区策略，但我仍然有同样的问题。

有什么想法吗？提前感谢。

[2022年5月17日编辑]

我用不同版本的SpringKafka做了更多的测试，最后，问题在SpringKafka2.3.13.RELEASE到SpringKafKa2.4.0.RELEASE的更新中重现。

根据2.4.0版本的发布公告：

2.4.0 kafka客户端与Spring for Apache Kafka 2.3不兼容，因此如果您希望使用2.4.0客户端，您必须升级到这个版本。有关如何覆盖jar版本的信息，请参见参考手册中的附录，尤其是当您使用Spring Boot进行依赖管理和/或使用测试嵌入式Kafka broker时。

我不确定…广告中描述的不相容性会导致这种行为吗？

如果您希望两个应用程序之间的负载均衡，则应将每个应用程序的并发性设置为5，否则我看不出为什么会有任何保证，即如果一个应用程序位于同一用户组中，则不应分配所有分区。

此外，kafka-客户端库已更新到这些Spring Kafka版本之间的新主要版本，因此这可能解释了行为上的差异-AFAIKSpring Kafka不会干扰分区分配，除非明确告知。

话虽如此，我不确定为什么您希望两个版本同时使用记录——如果业务逻辑发生变化，您将无法确定哪个版本将处理哪个分区/记录，除非您为每个版本手动分配分区。

你可以尝试的是 - 假设你正在部署绿色 - 在 autoStartup 设置为 false 的情况下部署它，确保应用部署正常，然后停止蓝色应用中的侦听器容器并启动绿色应用中的容器。如果出现任何问题，您可以停止绿色容器并重新启动蓝色容器作为回滚。

您可以将此过程添加为蓝色/绿色部署自动化的一部分，如果有暴露的endpoint，可能会沿着负载均衡器路由更改添加。

有关管理容器生命周期的更多信息，请参阅SpringKafka文档的这一部分。

编辑：根据@garyrussell的评论，这个问题确实与Spring Kafka无关，而是与在kafka-client版本之间为消费者分配订阅ID的方式的变化有关，“范围分配器对它们进行排序，所有旧订阅都在列表中排在第一位”。

在此GitHub问题中全面讨论此事。
