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.
For instance, tksheet. Adapting your current code to work with it will probably take a bit of work, but the payoff will be more than worth it. I've written a short example demonstrating the basic workings (using your code as a baseline), but you will most likely need the documentation too.
