How do you know when was a topic created in Kafka?

似乎有些主题是用错误数量的分区创建的.有没有办法知道主题创建的日期?据称，创建了一个名为test"的主题，其中包含 n 个分区.如何找到在 Kafka 上创建此测试"主题的日期和时间?

It seems that a few of the topics were created with a wrong number of partitions. Is there a way to know the date the topic was created? Supposedly, a topic with the name "test" was created with n number of partitions. How can I find the date and time when this "test" topic was created on Kafka?

推荐答案

可以看到Kafka主题创建时间(ctime)和上次修改时间(mtime)在动物园管理员统计.

You can see the Kafka topic creation time(ctime) and last modified time(mtime) in zookeeper stat.

首先登录zookeeper shell并添加命令stat"

First login to zookeeper shell and add command "stat "

kafka % bin/zookeeper-shell.sh localhost:2181 stat /brokers/topics/test-events

它将返回以下详细信息:

It will return below details:

Connecting to localhost:2181
