---------------------------------------
Assignee: Aljoscha Krettek
> Provide Timestamp in TimelyFlatMapFunction
> ------------------------------------------
>
> Key: FLINK-5012
> URL: https://issues.apache.org/jira/browse/FLINK-5012
> Project: Flink
> Issue Type: Improvement
> Components: Streaming
> Reporter: Aljoscha Krettek
> Assignee: Aljoscha Krettek
>
> Right now, {{TimelyFlatMapFunction}} does not give the timestamp of the
> element in {{flatMap()}}.
> The signature is currently this:
> {code}
> void flatMap(I value, TimerService timerService, Collector<O> out) throws
> Exception;
> {code}
> if we add the timestamp it would become this:
> {code}
> void flatMap(I value, Long timestamp, TimerService timerService, Collector<O>
> out) throws Exception;
> {code}
> The reason why it's a {{Long}} and not a {{long}} is that an element might
> not have a timestamp, in that case we should hand in {{null}} here.
> This is becoming quite look so we could add a {{Context}} parameter that
> provides access to the timestamp and timer service.
