Erik van Oosten updated FLINK-6928:
-----------------------------------
Description:
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.
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.
