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.
Cython is already a thing. It's a version of Python with type annotations that can be used to create bindings to existing C or C++ libraries. It has reasonably good support for numpy so I've used it for a few performance critical applications.
