It's DuckDB, but with a proper catalog on PostgreSQL with S3 for storage. It still takes quite a few steps to set up, so I put together a setup that runs on Hetzner.

It sets up a VPS with PostgreSQL, an S3 bucket, and a DuckDB init script that connects everything. One 'make all' command and it works. Used OpenTofu for the infra, PyInfra for server config.

Runs me about €9/mo with 1TB of storage. The VPS is a cx33 (4 vCPU, 8GB RAM) because Hetzner never has the cheaper tier in stock, maybe you'll get lucky.

Nothing fancy, but if you'd like to try out DuckLake, it should help you get going quickly!
