Paul Dix earlier today: "We're announcing the release of InfluxDB IOx, the new core of the database written in #rustlang and built with #apachearrow. It delivers infinite cardinality, tiered data storage, SQL compatibility and so much more."
I am the author of NoteCalc, and it warms my heart that my project is mentioned here :)
As a sidenote I would like to mention that NoteCalc is still in active (but slow) development, though I do it privately, and the next big release will be definitely this year.
