> Key: KAFKA-16892
> URL: https://issues.apache.org/jira/browse/KAFKA-16892
> Project: Kafka
> Issue Type: Bug
> Components: kraft
> Affects Versions: 3.4.0, 3.5.0, 3.6.0, 3.7.0
> Reporter: HanXu
> Assignee: HanXu
> Priority: Minor
>
> MetadataLoader#loadSnapshot get empty
> TopicsDelta.localChanges(brokerId).deletes
> Bug:
> 1. When generating MetadataDelta from Snapshot, TopicsDelta will first
> #replay(TopicRecord);
> 2. However, TopicsDelta directly creates a TopicDelta without any Partitions,
> instead of using the previous TopicImage;
> 3. Because TopicDelta.image has no Partitions, when TopicDelta#localChanges
> generates the deletes list, it returns empty deletes.
