-------------------------------
Assignee: Bowen Li
> Access to the current key in ProcessFunction after keyBy()
> ----------------------------------------------------------
>
> Key: FLINK-8560
> URL: https://issues.apache.org/jira/browse/FLINK-8560
> Project: Flink
> Issue Type: Wish
> Components: DataStream API
> Reporter: Jürgen Thomann
> Assignee: Bowen Li
> Priority: Minor
>
> Currently it is required to store the key of a keyBy() in the processElement
> method to have access to it in the OnTimerContext.
> This is not so good as you have to check in the processElement method for
> every element if the key is already stored and set it if it's not already set.
> A possible solution would adding OnTimerContext#getCurrentKey() or a similar
> method. Maybe having it in the open() method could maybe work as well.
