All Flink DataSet APIs are deprecated since Flink 1.18 and will be removed in a future Flink major version. You can still build your application in DataSet, but you should move to either the DataStream and/or Table API.

@Deprecated
 @PublicEvolving
public class PrintingOutputFormat<T>
extends org.apache.flink.api.common.io.RichOutputFormat<T>

Output format that prints results into either stdout or stderr.

Four possible format options: sinkIdentifier:taskId> output <- sinkIdentifier provided, parallelism > 1 sinkIdentifier> output <- sinkIdentifier provided, parallelism == 1 taskId> output <- no sinkIdentifier provided, parallelism > 1 output <- no sinkIdentifier provided, parallelism == 1
