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.
I'd prefer the K6 over the Q2 personally if those are the only things you're comparing. If you want the QMK software and don't care about losing the bluetooth you can flash it yourself, https://github.com/itspriddle/k6-qmk
