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 haven't done a ton with the API but a little and it does work well. I use the FDM SDK that is on github at https://github.com/marksull/fmcapi. There is an outdated video showing how it works at https://www.youtube.com/watch?v=4NIe3T-HjDw
