Just dropped a demo of chrondb — a PostgreSQL-compatible database that persists everything in Git.
Connect via psql, run SQL queries, and watch your data get versioned like code.

We built real document versioning on top of Git — with full history, point-in-time access, and chronological restoration.
This is the core of #ChronDB
👇 Here’s how it works under the hood

Every time I try to use GraalVM to generate a native image for a new project, it makes me angry

Not because GraalVM is bad, but because I'm dumb

I've been struggling for a week with a PR that works locally ('it works on my machine') but not in CI

I've never had to work so much with Socket in #Java as I'm working on the implementation of #chrondb.

Today I started playing around with implementing an SQL (#PostgreSQL-like) to perform all operations: select, insert, delete and update.

weekend of much study, implementing virtual commits in #chrondb using #Git internals (WalkRef and WalkTree) and implementing Redis protocol to connect to chrondb using existing Redis drivers

I'm developing #chrondb, a git-based database! I've already implemented the #PostgreSQL protocol, so you can use #psql to insert and query data. Git as a DB is real! 🚀 #database #opensource
