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.
It does take some time to set everything up to your liking though, but there are some great resources out there if you want to check it out. I've also tried compiling the ways I've been using Obsidian for math, you can check it out here (github repo). Theres some screenshots of my setup there too; scroll down.
