> The {{FlinkKafkaProducerBase}} supports routing records to topics besides the default topic, but the custom {{Partitioner}} interface does not follow this semantic.
> The partitioner is always invoked the {{partition}} method with the number of partitions in the default topic, and not the number of partitions of the current {{targetTopic}}.
