Thank you for your reply. I plan to repair the logic in kRaft together. In
addition, I will add an article to explain why sorting is needed and the
solution, and of course I will add the corresponding unit test. Thanks again
for your reply!

Subject: Re: [apache/kafka] createTopic need sort brokerMetadata (PR #11453)
@junrao commented on this pull request.
@shirenchuang : Thanks for the PR.
Could you add a unit test?
We are moving the logic in ZK to KRaft. In ReplicationControlManager, it
seems that createTopics() and createPartitions() don't sort the brokers during
reassignment. Do you plan to fix the issue there too? If not, I can file a
separate jira to track that.
In core/src/main/scala/kafka/server/ZkAdminManager.scala:
> @@ -152,7 +152,7 @@ class ZkAdminManager(val config: KafkaConfig,
responseCallback: Map[String, ApiError] => Unit): Unit = {
// 1. map over topics creating assignment and calling zookeeper - val
brokers = metadataCache.getAliveBrokers() + val brokers =
metadataCache.getAliveBrokers().toList.sortBy(_.id)
Could we add a comment why we want to sort the broker by ids?
