> Key: FLINK-3674
> URL: https://issues.apache.org/jira/browse/FLINK-3674
> Project: Flink
> Issue Type: New Feature
> Components: Streaming
> Affects Versions: 1.0.0
> Reporter: Stephan Ewen
> Assignee: Aljoscha Krettek
>
> I suggest to add an interface that UDFs can implement, which will let them be
> notified upon watermark updates.
> Example usage:
> {code}
> public interface EventTimeFunction {
> void onWatermark(Watermark watermark);
> }
> public class MyMapper implements MapFunction<String, String>,
> EventTimeFunction {
> private long currentEventTime = Long.MIN_VALUE;
> public String map(String value) {
> return value + " @ " + currentEventTime;
> }
> public void onWatermark(Watermark watermark) {
> currentEventTime = watermark.getTimestamp();
> }
> }
> {code}
