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.
Another option if you don't want to implement it yourself though is to use an already built library. I've been playing with YarnSpinner a little bit recently and I'm liking it so far. I can't give much more details than that, but it's maybe worth a look. At least for some reference.
