Thanks,I'm not sure I understand this, what I need is to have single a process subscribing multiple kafka topics, and have a switch clause for different topics in my SinkFunction, did you I need to change the way how the kafka producer to produce the message? Any pointer to code samples will be appreciated. Thanks AgainRichard

The `getTargetTopic` method is invoked for each record.
