help you fix your problem You can do two things in this case:
You can either use three PublishKafka_0_10 processors and configure them with three different topic names individually. If you want to stick with only one PublishKafka_0_10 processor then you can leverage the ExpressionLanguage support that the Topic property offers in PublishKafka_0_10 processor.

wish help you to fix your issue We have an incoming kafka topic with multiple Avro schema based messages serialized into it. , You can write a Kafka Streams application and use branch():
code :
KStream input = builder.stream("topic");
KStream[] splitStreams = input.branch(...);
splitStream[0].to("output-topic-1");
splitStream[1].to("output-topic-2");
// etc.
