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.
Lichess recently added external engine support (https://github.com/lichess-org/external-engine), so you can replace the crappy JavaScript-Stockfish with a real installed Stockfish (or any other engine I assume).
