Hej, Is it possible to extract the start and end window time stamps from within a window operator?
I have an event time based window that does a simple fold function. I want to put the output into elasticsearch and want to preserve the start and end timestamp of the data so I can directly compare it with related data. The only Idea I had so far was to manually keep track of the minimum and maximum timestamp found in a window and pass them along with the output. This is a quite bad approximation since the window I see depends alot on how the values are spaced out. Anyone an idea how to do this? cheers Martin
