> * props.put(StreamsConfig.APPLICATION_ID_CONFIG,
> "my-stream-processing-application");
> * props.put(StreamsConfig.BOOTSTRAP_SERVERS_CONFIG, "localhost:9092");
> * props.put(StreamsConfig.DEFAULT_KEY_SERDE_CLASS_CONFIG,
> Serdes.String().getClass());
> * props.put(StreamsConfig.DEFAULT_VALUE_SERDE_CLASS_CONFIG,
> Serdes.String().getClass());
> *
> * StreamsBuilder builder = new StreamsBuilder();
> * builder.<String, String>stream("my-input-topic").mapValues(value ->
> String.valueOf(value.length())).to("my-output-topic");
> *
> * KafkaStreams streams = new KafkaStreams(builder.build(), props);
