However, You can evaluate your time window, get the information of window of
which an event is a part from the context of processFunction or any
RichFunction you are passing the events to. So, on each event arrival you will
be able to check which window the element is part of and from Window object you
can fetch the information of window, start time, end time etc.

I think here apply function would receive only the events but not necessarily a
complete window at same time.

I am afraid there is no way to do that. At least I could not think of a way to
do it.
Maybe @aljoscha cc'ed could help here.

Hi,
I have a usecase where i want to join two streams. I am using coGroup for this
KeyBuilder leftKey = new
KeyBuilder(jobConfiguration.getConnectStream().getLeftKey());
KeyBuilder rightKey = new
KeyBuilder(jobConfiguration.getConnectStream().getRightKey());
leftSource.coGroup(rightSource).where(leftKey).equalTo(rightKey)
.window(...)
.apply()
.addSink(...);
For apply method i'm using RichCoGroupFunction. I am not able to find access to
Window object similar to
ProcessWindowFunction. I would be interested in extracting start time, end time
and key of the window
Plz suggest if there are any alternatives
