Package org.apache.iotdb.flink

Class IoTDBSink<IN>

  • Type Parameters:
    IN - the input data type
    All Implemented Interfaces:
    java.io.Serializable, org.apache.flink.api.common.functions.Function, org.apache.flink.api.common.functions.RichFunction, org.apache.flink.streaming.api.functions.sink.SinkFunction<IN>
    public class IoTDBSink<IN>
extends org.apache.flink.streaming.api.functions.sink.RichSinkFunction<IN>
    The `IoTDBSink` allows flink jobs to write events into IoTDB timeseries. By default send only one event after another, but you can change to batch by invoking `withBatchSize(int)`.
