>
> ReplicaManager [0] could generate a response having unexpected topics which
> have empty partitions. The root cause is it always generate the topic
> collection even though they have no matched partitions.
> That is not a issue to Kafka clients, since we loop the "partitions" to fill
> all future responses [1]. Hence, those unexpected topics won't be existent in
> the final results.
> However, that could be a issue to the users who implement Kafka client based
> on Kafka protocol [2]
