> 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.
