类 PrintSink<IN>

java.lang.Object

org.apache.flink.streaming.api.functions.sink.PrintSink<IN>

类型参数:

IN - Input record type

所有已实现的接口:

Serializable, org.apache.flink.api.connector.sink2.Sink<IN>

@PublicEvolving
public class PrintSink<IN>
extends Object
implements org.apache.flink.api.connector.sink2.Sink<IN>

Sink implementation writing every element to the standard output or standard error stream.

Four possible format options:

• sinkIdentifier:subtaskIndex> output <- sinkIdentifier provided and parallelism > 1,
• sinkIdentifier> output <- sinkIdentifier provided and parallelism == 1
• subtaskIndex> output <- no sinkIdentifier provided and parallelism > 1
• output <- no sinkIdentifier provided and parallelism == 1
