> Today {{KStream.print}} use the hard-coded result string as:
> {code}
> "[" + this.streamName + "]: " + keyToPrint + " , " + valueToPrint
> {code}
> And some users are asking to augment this so that they can customize the
> output string as {{KStream.print(KeyValueMapper<K, V, String>)}} :
> {code}
> "[" + this.streamName + "]: " + mapper.apply(keyToPrint, valueToPrint)
> {code}
