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've worked a lot on a media workflow server with the intention that it can be used by both open source and non-open source projects (https://kalldrexx.github.io/mmids/). I licensed it as MIT specifically because if some users want to customize it and add proprietary integrations they can do so without being forced to open-source their integrations.
