> In DefaultEventHandler, for a batch of messages, it picks a random partition
> per message (when there is no key specified). This means that it can send up
> to P produce requests where P is the number of partitions in a topic. A
> better way is probably to pick a single random partition for the whole batch
> of messages. This will reduce the number of produce requests.
