David Arthur 254335d24a KAFKA-15799 Handle full metadata updates on ZK brokers (#14719) ... This patch adds the concept of a "Full" UpdateMetadataRequest, similar to what is used in LeaderAndIsr. A new tagged field is added to UpdateMetadataRequest at version 8 which allows the KRaft controller to indicate if a UMR contains all the metadata or not. Since UMR is implicitly treated as incremental by the ZK broker, we needed a way to detect topic deletions when the KRaft broker sends a metadata snapshot to the ZK broker. By sending a "Full" flag, the broker can now compare existing topic IDs to incoming topic IDs and calculate which topics should be removed from the MetadataCache. This patch only removes deleted topics from the MetadataCache. Partition/log management was implemented in KAFKA-15605. Reviewers: Colin P. McCabe <cmccabe@apache.org>		2023-11-16 14:39:12 -08:00
