Мне нужно собрать некоторые данные датчиков, и я экспериментирую с оконным агрегированием для PoC / учебного проекта.
После исследования здесь и там и множества попыток я придумал следующий код, который, кажется, работает.
На самом деле я получаю сообщения, показывающие ожидаемые результаты, и я также вижу, как десериализация / сериализация объекта SensorData происходит через поток.
И я могу увидеть окончательный результат в теме вывода.
В этом и заключается проблема: после того, как первый результат записан в теме вывода, поток падает, и он падает раньше или позже, в зависимости от длины commitMs.
Есть идеи? Я что-то здесь не так делаю?
Я использую изображение докера landoop / fast-data-dev для проверки этого.
long commitMs = TBD;
Properties config = new Properties();
config.put(StreamsConfig.APPLICATION_ID_CONFIG, "sensor-data-stream-analyzer");
config.put(StreamsConfig.BOOTSTRAP_SERVERS_CONFIG, "kafka-cluster1:9092");

final Serde<SensorReport> jsonSerde = Serdes.serdeFrom(jsonSerializer, jsonDeserializer);
final Serde<String> stringSerde = Serdes.String();
final Serde<Long> longSerde = Serdes.Long();
StreamsBuilder builder = new StreamsBuilder();
KStream<String, SensorReport> stream =
builder.stream(inputTopic, Consumed.with(stringSerde, jsonSerde));
