如何在Kafka中查看特定主题的保留 [英] How to see the retention for a particular topic in kafka

问题描述

我想查看为特定主题设置的保留期.有什么命令吗?我尝试过

I want to see the retention period set for a particular topic. Is there any command? I tried with

bin/kafka-topics.sh --zookeeper hostname:2181 --alter --config retention.ms=172800000 --topic <topic_name>

用于删除2天前的数据.但是我想看看所有主题的保留期都设置了多少天.

for deleting 2 days old data. But I want to see how many days are set in the retention period for all the topics.

推荐答案

如果您更改了主题并希望查看主题配置，则以下命令将很有帮助

If you have altered a topic and want to view the topic configuration the following command will be helpful

kafka-topics.sh --zookeeper localhost:2181 --describe --topics-with-overrides

这将仅描述主题以及配置设置与集群默认设置不同的配置.

This will describe only the topics along with configurations that have configurations set that differ from the cluster defaults.

如果要查看所有主题的配置您可以在服务器中 log.retention.hours 或 log.retention.ms 查看这些属性..properties 在kafka的配置目录中.

If you want to view the configurations for all topic Either you can view these properties log.retention.hours or log.retention.ms in server.properties in kafka config directory.
