I use a control system (50K+ parameters). i would like to take a snapshot/backup of a running configuration and save all the 50K+ parameters in one file. A feature I need is to compare snapshot with each others.
For example: how does the current configuration compare to the snapshot taken 3 weeks ago. 1/ list of parameters to save are in a table of a h5 (50K+ parameters) 2/ take a snapshot (for each row extend with value of parameter) 3/ compare new snapshot to old snapshot where parameter names are the same ( with a tolerance on the parameter let's say of 1% up to 3% function of parameter) Also is there a way to easily edit h5 files (not sure vitables can do that based on its old documentation) and add a parameter in a table for future backup. I am interested in h5 because my parameters can be classified in /machine_id/systems/subsystems all of which could be groups. would be nice for browsing and selective restore. Any info on vitables and editable entries/row in tables? At this point, I am not yet convinced I should use h5/pytables yet... just exploring....
