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.
You can look into a program called dovi_tool which can do all kinds of operations on DV tracks, including combining base & enhancement layers from separate tracks into a single track if I'm not mistaken.
