I'm assuming this means for use in AF Analytics. If so, then yes! DataLink Advanced Queries (with filtering) are powerful and useful, and so painful to do in PI AF. Thank you!

Hi Rick,
We are considering how to implement Data Quality in an upcoming release. A subset of that is if data is stale. If you can help us gather more customer use cases to better document the problem, and help us get a sense of how many customers would benefit from this feature, that would be extremely helpful.
Specifically, what would be very helpful is the requirements customers have to determine when a data point is stale. We are making a serious effort to simplify the management of the PI System, so we would like to be able to avoid asking users to spend time configuring yet another parameter.

Distributing resources is big for our customers with a heavy analytics load. We've ended up offloading a lot of calculations to other engines/dbs because of the performance limitations in analytics. It would be a dream if we could do it all in AF in realtime through a distributed model, but until then it's pragmatic to do calculations post-facto and feed that back to PI.
