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.
I've played a bit with https://github.com/RobertCsordas/OnyxNoteRenderer (mentioned in this thread https://www.reddit.com/r/Onyx_Boox/comments/k83t1a/vector_export_of_notes/). This generates rendered PDFs from your notes without any cloud account on your PC. The results look promising.
