有人能说memberassignment是从哪个模块导入的吗？
memberassignment.decode（member\u assignment）中的for（主题，分区）。assignment：

你用过吗https://github.com/quantifind/kafkaoffsetmonitor 用于监控消费滞后。它适用于0.8.2.0

如果我理解正确，你可以 HighwaterMarkOffset 从 FetchResponse . 通过这种方式，您将知道分区末尾的偏移量是多少，并能够将其与当前确认的偏移量或此分区中最后一条消息的偏移量进行比较 FetchResponse 例如。
此处显示详细信息

以下是代码片段，请确保在活动控制器中运行此程序。引导服务器是活动的控制器ip。
