-------------------------------------

             Summary: Allow the FlinkKafkaProducer to send data to multiple topics
                 Key: FLINK-3658
                 URL: https://issues.apache.org/jira/browse/FLINK-3658
             Project: Flink
          Issue Type: Improvement
          Components: Kafka Connector
    Affects Versions: 1.0.0
            Reporter: Robert Metzger
            Assignee: Robert Metzger


Currently, the FlinkKafkaProducer is sending all events to one topic defined when creating the producer.

We could allow users to send messages to multiple topics by extending the {{KeyedSerializationSchema}} by a method {{public String getTargetTopic(T element)} which overrides the default topic if the return value is not null.
