DuckLake on Hetzner: Your own data lakehouse for under €15 a month
summary
Builds a working DuckLake using DuckDB 1.5 + PostgreSQL + Hetzner object storage and an infrastructure-as-code script that deploys in 3 minutes to a Hetzner VPS running Ubuntu; claims total running cost of under €15/month and shows tests that validate the deployment. Notes Hetzner is ~one third the price of AWS historically but faced a ~70% recent price hike, warns Hetzner S3 lacks full S3 features, RBAC is limited, and a production checklist and GitHub repos fill the gaps.
