A brief discussion on using FlinkKafkaProducer to implement Exactly Once semantics on the sink side
Abstract In some important flink data processing scenarios, it is necessary to implement Exactly Once data processing. Exactly Once means that when flink processes data, it can ensure that data is not lost and data is not repeated. The entire flink processing link is roughly divided into three links: Source -> Transform -> Sink. Selecting […]
