Relaxed Radix Balanced Trees (2024)

Clojure uses Persistent Vectors (PVs) which support lookups, updates, and appends all in ‘effectively’ constant time. However, it doesn’t have efficient insert or merge operations.

A vending machine, on the internet
These days, every new business seems to be a SaaS. I remember when software worked differently: you bought it, installed it, and used it without having to create an account, remember a password, or even connect to the internet. Your data lived on your C drive, and you were in control. Software was a tool, like a…
