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.
Like it says very experimental (doesn't even use cargo), but there's some interesting content in the docs directory and why they didn't choose any of the existing options (cxx, autocxx, bindgen), especially the design document.
