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.
Gnome's integrated screen recorder for wayland didn't arrive until 2022 IIRC.
Blue-recorder, green-recorder (https://github.com/mhsabbagh/green-recorder), etc. were around to fill in the gap at the time and may still be useful for special cases.
