Review comment:
Any reason to call future.get() here? We can return a Future for this
method, this will block the request thread for waiting the entry read.

Review comment:
We can introduce a new API TopicStats getStats(String topic,
GetStatsOptions options);
So can we can introduce more params without breaking the API.

Better to use a consistent name.

Review comment:
We can't change the API directly, this will introduce a compatibility
issue while users upgrade to the new version.
