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.
As proof of concept several years ago, I wrote RealmIncrementalStore. Though it’s not maintained and only there for experimentation, you’ll get an idea how to write one by looking at its internals.
