[jira] [Updated] (FLINK-3658) Allow the FlinkKafkaProducer to send data to multiple topics

     [ https://issues.apache.org/jira/browse/FLINK-3658?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Robert Metzger updated FLINK-3658:
----------------------------------
    Description: 
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.
