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.
Check out pandas-flavor. It's a library that lets you register methods to dataframes. There's definitely a time and a place for OO in pandas data processing but your examples can probably be more simply expressed as methods and pandas flavor can make them easy to "find" as extensions of the frame.
