Currently, if you want to store predictions for 1 day, 2 days, 3 days, etc. into the future, you must create a different PI tag for each distance into the future.
Future data tags should support 2 timestamps: the timestamp that the predicted valu...
Separate priority setting for Data Read and Data Write
Data Read and Date Write (Buffering) from/to PI Data Archive is based on the priority settings in PI SDK and PSE. We have a architecture of 6 member PI collective and all the source data is not buffered to the individual collective. Hence for othe...

Reduce archive file size by eliminating unused record numbers
Background:
On a Data Archive where many points have been deleted, there will be many unused record numbers. Since the size of an archive file is tied to the highest existing record number (for performance reasons), this can result in archive file...
Ability for admins to restrict PI Data query to 2 years at a time.
I would like to restrict PI Vision users from pulling data for more than 2 years at a stretch. This setting should also restrict the PI Data link as well. This will make the software more robust to query timeout. Just let users know they need to a...

It would be interesting to have a GUI, maybe inside PI SMT, that would allow users to configure their PIBackups directly without having to mess around in 2-3 batch files.
Checkboxes for the most common options, Active/inactive box etc. You could...
Automated re-compression/average after a period of time
As a PI Administrator, currently there is no way to compress or average (then delete) your data automatically after an event reaches a certain age. It would be nice to have the ability to automatically compress or average specific tags after the e...
Optimize and compress non-primary historic archive files
Currently, the same file format is used for primary and non-primary historic archive files. This does not make much sense since the two types are used very differently. For the primary archive: Write operations should be fast since it is collectin...

PI SMT: some plugins missing features for future data
Certain plugins in PI SMT do not have features to support future data
1. Snapshot and Archive Statistics (is available only through piartool)
2. Current Data does not subscribe to timeseries in Update Manager
3. Stale and Bad tags
Currently, there are two methods to 'shift' archives:
1. "Archive_AutoArchiveFileRoot" set to blank
2. "Archive_OverwriteDataOnAutoShiftFailure" enabled
Neither method shifts to dynamic archives. We have three sites that merged PI servers, thus ha...
