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 saner/slacker option would be to get one device to capture all the channels and use just ALSA with Ardour: Focusrite Scarlett 18i20 has the best Linux GUI controls alsa-scarlett-gui Behringer Xair X12 has Linux GUI mixer for ALSA. Soundcraft U12 has a browser-accessible mixer. Both of these are said to have noisy preamps which isn't a problem for recording line level
