We've been working on updating our demos and samples for the RTM changes of StreamInsight. I'll detail these as I come across them.
The first is that there is a change to the HoppingWindow. The first two parameters are the same in the constructor but the third parameter is now required. It is the HoppingWindowOutputPolicy. Currently, there is only a single option for this which is ClipToWindowEnd.
A similar change happened to the TumblingWindow. Curiously, it also takes a HoppingWindowOutputPolicy. I suppose that makes sense though as it is really just a special case of a HoppingWindow.
SnapshotWindow also now has a required parameter but in this case it's a SnapshotWindowOutputPolicy. The option for this policy is just called Clip.
Here are some examples of creating HoppingWindow, TumblingWindow and SnapshotWindow.
var queryOutput = from w in input.HoppingWindow
(TimeSpan.FromMinutes(1),
TimeSpan.FromSeconds(10),
HoppingWindowOutputPolicy.ClipToWindowEnd)
select new { VehiclesPerMinute = w.Count() };
var queryOutput = from w in input.TumblingWindow
(TimeSpan.FromSeconds(10),
HoppingWindowOutputPolicy.ClipToWindowEnd)
select new { VehiclesPer10Seconds = w.Count() };
var queryOutput = from w in input.SnapshotWindow
(SnapshotWindowOutputPolicy.Clip)
select new { VehiclesPerWhat = w.Count() };
