James Cheng commented on KAFKA-3809:
------------------------------------
Ah, I had missed that one. KAFKA-3234 handles auto-generation, as well as
renaming and deprecation of old config names. Is there any benefit to doing the
work in two parts, instead of doing it all at once?
> Auto-generate documentation for topic-level configuration

> Key: KAFKA-3809
> URL: https://issues.apache.org/jira/browse/KAFKA-3809
> Project: Kafka
> Issue Type: Bug
> Reporter: James Cheng
> Assignee: James Cheng
> Attachments: configuration.html, topic_config.html

>
> The documentation for topic-level configuration is not auto-generated from
> the code. configuration.html still contains hand-maintained documentation.
> I noticed this because I wanted to set message.timestamp.type on a topic, and
> didn't see that it was supported, but grepped through the code and it looked
> like it was.
> The code to auto-generate the docs is quite close, but needs some additional
> work. In particular, topic-level configuration is different from all the
> other ConfigDefs in that topic-level configuration docs list the broker-level
> config that they inherit from. We would need to have a way to show what
> broker-level config applies to each topic-level config.
