Apache kafka 如何重置卡夫卡的消费群体？

不确定标题是否正确。。。无论如何，假设我有以下场景（在运行测试时经常发生这种情况）：

• 使用者从具有单个分区和组id测试的主题开始

• 我不使用

  close（）

• 我重新开始相同的测试

使用者开始输出一些日志：

解决这些问题的唯一方法是：

• 杀死卡夫卡及其存储（因此有关主题的元数据已消失）
• 更改消费者组id

---

有没有其他不涉及上述内容的方法来解决这种情况？

您正在寻找的是本主题的开头

我认为在脏元数据状态下执行此操作的安全方法是：

consumer.seekToBeginning(Collections.emptySet()) // Rewind (lazy) all assigned partitions
consumer.poll(0) // Actually rewind by forcing a poll

---

您可以为消费组中的所有主题分区提交0个偏移量这有什么可能。。。我在尝试加入集群时会出现这种行为。我怎样才能提交呢？zookeeper-shell.sh脚本有一种方法可以做到这一点。也许，这会有所帮助：哦，好吧，我还以为你在谈论使用卡夫卡api呢
