类 KafkaRichSinkFunction

  • 所有已实现的接口:
    Serializable, org.apache.flink.api.common.functions.Function, org.apache.flink.api.common.functions.RichFunction, org.apache.flink.streaming.api.functions.sink.SinkFunction<org.apache.flink.table.data.RowData>
    public class KafkaRichSinkFunction
extends org.apache.flink.streaming.api.functions.sink.RichSinkFunction<org.apache.flink.table.data.RowData>
    自定义 sink 写入 kafka。 duckula的formate会把 opt_type字段设置为整个记录的opttype.这样后续就可以做为upsetkafka或appendkafka继续使用。 而如果是json formate，则不能做为upsetkafka做为后流使用。只能做为appendkafka供后流使用。
