Subject Generate timestamps in front of event for event time windows
Date Wed, 03 Aug 2016 18:29:36 GMT
Hey guys,

I am trying to use event time along with a custom window to capture a
subset of events.  The problem I am running into is that it seems that
event that generates the timestamp/watermark arrives in the window before
the onEventTime() call is made that closes the window.  Example:

Window is supposed to capture 5 minutes of events after first event arrives
Event 1: timestamp 12:01 - registers event timer for 12:06
Event 2: timestamp 12:03
Event 3: timestamp 12:20 - fires and purges window

I get all three events in the window, instead of just the two the are
really within the 5 minute window.

Is there someway to force the timestamp to arrive in the window before the
event that generated it?
