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.
Here's the github repo, it was just open sourced last week. You can compile it from source now, and I imagine the UI frontends will be updated in a couple of weeks. IIRC, compiling directly to other languages is now possible, although I'm not sure how much that impacts your use case.
