How to update the description of Kafka topic

Question

是否为此设想了一个占位符，还是主题名称是唯一必须足够描述的属性？

Answer 1

No, There is no placeholder where you can describe what a kafka topic contains as a topic property. You should make the topic name self explanatory.

You can see what all properties a topic can have : https://kafka.apache.org/documentation/#topicconfigs
