> Allow access to "time" in ProcessWindowFunction.Context
> -------------------------------------------------------

> Key: FLINK-4953
> URL: https://issues.apache.org/jira/browse/FLINK-4953
> Project: Flink
> Issue Type: Improvement
> Components: DataStream API
> Reporter: Manu Zhang
> Assignee: Manu Zhang
>
> The recently added {{ProcessWindowFunction}} has a {{Context}} object that
> allows querying some additional information about the window firing that we
> are processing. Right now, this is only the window for which the firing is
> happening. We should extends this with methods that allow querying the
> current processing time and the current watermark.
> Original text by issue creator: This is similar to FLINK-3674 but exposing
> time information in window functions. Currently when a timer is fired, all
> states in a window will be returned to users, including those after the
> timer. This change will allow users to filter out states after the timer
> based on time info.
