Kevin Wu updated KAFKA-21240:
-----------------------------
Description: In KRaft mode, `KRaftMetadataCache` rebuilds every partition's
metadata on every MetadataRequest. This is different than in ZK Kafka, where
the controller would precompute parts of the MetadataReponse such as offline
replicas.
> KRaftMetadataCache should cache metadata request information per image
