What are the plans, if any, to provide some of the PI related aggregates that we see in Performance Equations in to StreamInsight as User Defined Aggregates? Seems that we can get PI data in, but then any common functions that are used in PI (typically PEs) are not exposed. This leads to them being custom developed and potentially different to algorithms to what PI is using.
Standard Deviation in PE is a good example. I see there are examples of creating an UDA extension class for standard deviation out on the web for StreamInsight, but wouldn't it make sense to have all functions from PE, Notifications, etc available to StreamInsight?
What are others doing? Creating your own framework of UDAs?
