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 base M2 is plenty cheap and pack a lot of punch in it, it flies through my RAW edits in darktable (https://www.darktable.org/) even with just 8GB of RAM. (Granted I don't have much things else running when using darktable).
