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.
https://github.com/CedricFR/dataenforce enforces column names and types, no versioning though. My first instinct is that important data should be stored in databases which enforce schemas, and that should be separate from the python code that reads it.
