Please keep the discussion on the mailing list rather than commenting on the wiki (wiki discussions get unwieldy fast).
Motivation
Currently when we use deleteTopics API with topic deletion disabled on server, then the client cannot get a response and fails returning a timeout error.
This KIP is to return proper error code in above mentioned scenario.
Public Interfaces
If topic deletion feature is disabled , DeleteTopicsAPI response
will return TOPIC_DELETION_DISABLED error code.
public class TopicDeletionDisabledException extends ApiException {
private static final long serialVersionUID = 1L;
public TopicDeletionDisabledException() {
}
public TopicDeletionDisabledException(String message) {
super(message);
}
}
Proposed Changes
The proposal is to
- Bump DeleteTopics protocol version to V3 (with same schema as V2)
- If topic deletion is disabled on broker:
For V2 and orders versions, return UNKNOWN_SERVER_ERROR
For V3 and above requests, return TopicDeletionDisabledException
Compatibility, Deprecation, and Migration Plan
- Instead of timing out, V2 and older version delete topic requests will get UNKNOWN_SERVER_ERROR.
