PI SDK Buffering Limitations

Hi,

 

Are there any updates being worked on for PI SDK Buffering?

Not being able to make edits to data/annotations using PI SDK Buffering is a pain.

 

We need to support HA collectives and with these limitations with PI SDK  buffering its not worth enabling as it supports the very basics of what we need to do.

 

LIMITATIONS (from the documentations I am referring to):
In addition, the following calls that edit existing events do not support buffering in PI SDK 1.4.0:
IPIData2.ReplaceValue
IPIData2.RemoveSpecifiedValues
IPIData2.RemoveValues

 

Data that is not buffered. The following data is not included in PI SDK buffering:
Annotations (except annotations that are created when the corresponding event is created)
Batch data
Data edits and deletes
Configuration changes (for example, changes to the PI Point database or PI Module Database)

 

Cheers,
