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.
The triggers are detected as buttons by default in some software (using d-input mode). Anything using the SDL2 community database shouldn't have this problem. I don't remember if RetroPie uses SDL2 or not. If not you might just need to edit a config file to rebind them to axes instead of buttons. I had to do this with Moonlight and linux Steam before the SDL database was updated.
