Lakehouse Demo

Lakehouse architecture demo entirely on local machine with no cloud dependency.

⚠️ Note

This repo is based on this excellent Medium article by Gilles Philippart.
All credit for the architecture and original code goes to the author. I've made minor modifications (e.g., config tweaks, test queries) as part of my personal learning.
