InfluxDB
Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
A cleaner solution would be to use https://github.com/rubenaleman/kde-plasma-backup but I can't guarantee anything as I have not personally used it yet. Looking at the script itself shows where to find many if not all of the important config locations though.
