Hello guys,


I'm studying a little bit of data flow in the PI System and I have a question on which tool runs compression. From the PI Data Archive 2016 System Management Guide it says that the PI Snapshoot Subsystem runs compression on the snapshoot values. But I know that there is the PI Buffer Subsytem that can also run compression.


Can anyone explain the difference between these two tools? Is it that the PI Buffer Subsystem is allocated with the interface node and the PI Snashoot Subsystem is part of the Data Archive itself?


At last, if I have the PI Buffer Subsystem set up, will the PI Snapshoot Subsystem run compression test too?


Thank you!
