PrintingOutputFormat (Flink : Java 1.18.1-cp2 API)

java.lang.Object
- org.apache.flink.api.common.io.RichOutputFormat<T>
- - org.apache.flink.api.java.io.PrintingOutputFormat<T>

Type Parameters:

T - Input record type

All Implemented Interfaces:

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

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
