---------------------------------------
Summary: Clarify UpdateFeatures.max_version_level deletion
semantics
Key: KAFKA-21332
URL: https://issues.apache.org/jira/browse/KAFKA-21332
Project: Kafka
Issue Type: Bug
Reporter: Federico Valeri
Assignee: Federico Valeri
The {{UpdateFeatures}} protocol documentation states that a
{{max_version_level}} value less than {{1}} can be used to request deletion of
the finalized feature. However, Kafka trunk rejects negative values and uses
{{0}} to request deletion.
Update the protocol documentation to state explicitly that {{0}} requests
deletion and negative values are invalid.
