Add the ability to select a subset of PI Points from a PI Data Archive
The PI System Connector allows to include PI Point replication directly from the PI Data Archive even if they are not reference in the PI AF hierarchy with the "Include all PI points from this PI Data Archive" option.
I would like to replicate only some PI Points that are not referenced, not all. This would remove the need to maintain both a PI to PI and a PI System Connector.
I could create a bogus AF Database referencing those points but I would prefer not to.
As suggested in the description of this item, PI System Connector uses AF database as the primary source and thus any filtering that is desired at the PI Tag level can be accomplished by referencing only those tags in the source AF database. If users would only like to replicate PI tags without an AF model, then PI-to-PI interface can serve as an alternate option.
This request seems slightly different than our use case, but the functionality may resolve the issue we have seen. When trying to replicate a small sub-branch of a large AF structure, there is not an option to synchronize only the PI points referenced in that branch alone, and rather the options are to replicate all PI points in the entire AF database or all PI points in the entire PI Data Archive. I believe OSIsoft has this on their list to fix in the next version, but definitely was a surprise when instead of 1000's of PI points the connector replicated 1,000,000's of PI points (since this AF database contains about 80% of the points in the entire data archive).

Instead of (or in addition to) using PointSource, I would suggest supporting regular expression

One useful way to define the subset of PI Points would be via point source.
