EventTimeProcessFunction (Flink : DataStream : API 2.1.0 API)

All Superinterfaces:

org.apache.flink.api.common.functions.Function, ProcessFunction, Serializable

All Known Subinterfaces:

OneInputEventTimeStreamProcessFunction<IN,OUT>, TwoInputBroadcastEventTimeStreamProcessFunction<IN1,IN2,OUT>, TwoInputNonBroadcastEventTimeStreamProcessFunction<IN1,IN2,OUT>, TwoOutputEventTimeStreamProcessFunction<IN,OUT1,OUT2>
```
@Experimental
public interface EventTimeProcessFunction
extends ProcessFunction
```
The base interface for event time processing, indicating that the ProcessFunction will be enriched with event time processing functions, such as registering event timers and handle event time watermarks.
Note that registering event timers can only be used with KeyedPartitionStream.
