Is there a way to retain all events and just add or delete events as desired in StreamInsight? In Esper there is a method called keepall() witch can be applied on a window. This method keeps all incoming events and you can have different queries for inserting events in the window or deleting them.
I tried using Hopping, Snaphot, Tumbling and Count Window in StreamInsight, but none of them has the above mentioned functionality.
Thanks.
You should be able to do something like you are asking about with a window using a User-Defined Operator. Here's a link to the MSDN documentation: http://msdn.microsoft.com/en-us/library/ee842720(v=sql.111).aspx
If you want to interact with the events in a procedural way without a window then take a look at User-Defined Stream Operators. The docs for that are here: http://msdn.microsoft.com/en-us/library/hh290514(v=sql.111).aspx
With more detail about what you are trying to accomplish, I can give you a better answer.
