https://cwiki.apache.org/confluence/display/KAFKA/KIP-407%3A+Kafka+Connect+support+override+worker+kafka+api+configuration+with+connector+configuration+that+post+by+rest+api was created by the author and a discussion thread was never started.
This appears to very similar to (or rather a subset of) https://issues.apache.org/jira/browse/KAFKA-6890 / https://cwiki.apache.org/confluence/display/KAFKA/KIP-296%3A+Connector+level+configurability+for+client+configs, which IMO has the correct scope and where a discussion is taking place about the requirements and user experience. This proposal seems to differ from KAFKA-6890 / KIP-296 is that the approach proposed here only addresses connector configurations specified via the REST API, and not via configuration files passed to the standalone Connect worker. This would be a significant departure from the current behavior, where the REST API and file configurations are completely compatible. It's fine to leave this open for further discussion, but I would prefer to withdraw this KIP and instead focus the discussion on KIP-296. Thoughts? Randall
