> When using a Kafka sink, the defaultTopic needs to exist even when it is 
> never used. It would be nice if fetching partition information for the 
> default topic would be delayed until the moment a topic is actually used.
> Cause: {{FlinkKafkaProducerBase.open}} fetches partition information for the 
> default topic.
> In addition, it would be nice if we could signal that the defaultTopic is not 
> needed by passing {{null}}. Currently, a value for the defaultTopic is 
> required.
