> -------------------------------------------------
>
> Key: FLINK-4395
> URL: https://issues.apache.org/jira/browse/FLINK-4395
> Project: Flink
> Issue Type: Improvement
> Components: CEP
> Reporter: Till Rohrmann
> Assignee: Ivan Mushketyk
> Priority: Minor
>
> At the moment elements are only processed after the CEP operator has received
> a watermark larger than the elements (in EventTime mode). In case of late
> arrivals this means that the late elements are not processed until the next
> watermark has arrived.
> In order to decrease the latency for this scenario, I propose to eagerly
> process late arrivals in the CEP operator.
