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.
However, std::function which can be used for storing multiple closures can indeed heap allocated. Since this is undesirable, I use an equivalent with static fixed storage instead: https://github.com/jcelerier/smallfunction/blob/master/smallfun/include/smallfun.hpp which gives me a compile error if I try to stuff too much data in there.
