Я управлял брокером зоопарка и кафкой, но я не руководил производителем кафки.Я запустил код потоковой передачи и распечатал здесь нефильтрованный поток.Мой вопрос заключается в том, почему я получаю эти потоки данных, а именно:
{"vehicleId": "0", "lon": "0", "lat": "0", "ts ":" 0 "}
{" vehicleId ":" 0 "," lon ":" 0 "," lat ":" 0 "," ts ":" 0 "}
Хотя я не управляю продюсером?Что означают эти сообщения ниже?
