Kafka streams provides State Store, which is a preferred way to implement stateful (and dynamically controlled) streams in the case of Kafka Streams implementation.For our implementation we are going to use a single (key/value) store containing an instance of TemperatureControl record for every SensorID known to the system. But a bunch of errors withing a small window of time could indicate a bigger issue, so it’s better to shutdown. While the code doesn’t inspect the type of the exception, that’s another valid approach as well.
