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 also consider taking a look at https://github.com/HorlogeSkynet/thunderbird-user.js I ported it from Firefox to Thunderbird, compared/looked at source. I handed over maintainer ship to someone else though and I don't personally use Thunderbird anymore. Nowadays I use a text client https://neomutt.org with a setup very similar to this.
I don't use the RSS support, I use newsboat instead.
