* More concretely, we show how to use the {@link KStream#process(ProcessorSupplier, String...)}

* Tip: Users that want to use {@link KStream#process(ProcessorSupplier, String...)} would need to
* include a custom {@link org.apache.kafka.streams.processor.api.Processor}. Keep in mind though that
* the return type of {@link KStream#process(ProcessorSupplier, String...)} is `void`, which means
* you cannot add further operators (such as `to()` as we do below) after having called `process()`.
* If you need to add further operators, you'd have to use `transform()` as we do in this example.
* <p>
* Note: This example uses lambda expressions and thus works with Java 8+ only.
