>                 URL: https://issues.apache.org/jira/browse/KAFKA-12682
>             Project: Kafka
>          Issue Type: Bug
>          Components: core
>    Affects Versions: 2.8.0
>            Reporter: jacky
>            Priority: Minor
>
> In version 2.8, MetadataPartitionsBuilder has the field _localChanged and 
> _localRemoved which record the change and delete partition, but we always 
> process _localChanged partitions, and then _localRemoved in the 
> kafka.server.RaftReplicaManager#handleMetadataRecords, not respect the 
> original order, for example, 
> 1. migrate the partition p1 from b0 to b1;
> 2. change the leader of p1 
> 3.migrate p1 from b1 to b0
> and the _localRemoved will delete the p1 at last.
> and I think MetadataPartition should include topic uuid, and the topic name 
> is optional, the topic name only can find the partition by the 
> for example,
> create topic t1, delete topic t1, create topic t1, change leader of p1
> and then compact the records 
> delete topic t1, change t1, p1
> but currently, implementation will be
> 1. process change t1, p1
> 2. process delete topic t1
> but the MetadataPartition doesn't include topic uuid, it only include topic 
> name, when to stop, it can't find the origin topic id, and find the latest 
> the topic id, but it's not right.
