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.
Some people regard the Arduino-IDE as clunky (it is), but I side-step that by compiling with makefiles.
The build script calls AVR-GCC, with the -std=gnu++11 flag. Source.
The PIO stuff could be very cool https://github.com/raspberrypi/pico-examples/tree/master/pio
