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.
I think a good way to learn how to write practical stuff is to study already existing code, for example glib, or even glibc which is an implementation of standard C library. I can also suggest to study ut* libraries, for example utlist, utstring, etc. Even sds strings and bstring come to mind as a good study material.
