Description

Running the following code produces different behavior between ZooKeeper and KRaft:

DescribeTopicsOptions options = new DescribeTopicsOptions().includeAuthorizedOperations(false);
TopicCollection topics = TopicCollection.ofTopicNames(Collections.singletonList(topic));
DescribeTopicsResult describeTopicsResult = admin.describeTopics(topics, options);
TopicDescription topicDescription = describeTopicsResult.topicNameValues().get(topic).get();
System.out.println(topicDescription.authorizedOperations());

With ZooKeeper this print null, and with KRaft it prints [ALTER, READ, DELETE, ALTER_CONFIGS, CREATE, DESCRIBE_CONFIGS, WRITE, DESCRIBE].

The Admin.getTopicDescriptionFromDescribeTopicsResponseTopic does not take into account the options provided to describeTopics() and always populates the authorizedOperations field.
