Hi Radu,
If I’m not mistaken, then it’s not possible with the current GlobalWindow
implementation. However, you could extend the GlobalWindow which adds a new
field into which the timestamp of the triggering element is stored. This
field can then be read from within the WindowFunction to retrieve the
latest timestamp.
Cheers,
Till
