回复kojie.fu的问题

[linghongbo008 <li...@gmail.com>]

 这个意识是这样的，我们有一个如下的场景：
一个A系统往kafka队列写消息，一个B系统负责从kafka消费消息
现可能由于某种原因B系统无法读取kafka的消息，此时A系统还一直在往队列写消息，所以当我们把B系统
修复起来后（比如说花了2天时间修复了），我们不想让B系统还从原来的offset读取数据，而是想从某个时间点开始读取数据，
不知道kafka有类似的 时间戳和offset对应的接口没？

Hello,

I do not fully understanding your question, did you mean that you want to
know when a message with certain offset is produced?
