PetroDB

Public petroleum datasets served as a partitioned parquet tree, designed for remote columnar queries with DuckDB httpfs (HTTP Range pushdown).

This Hugging Face dataset repo hosts the parquet bytes only. It mirrors the parquet/ root and is queried directly via resolve URLs, which honour HTTP Range requests so consumers fetch only the row groups a predicate needs.

INSTALL httpfs; LOAD httpfs;
SELECT *
FROM 'https://huggingface.co/datasets/sumpalabs/petrodb/resolve/main/<dataset>/...';

The human-facing landing page, per-dataset schema docs, and discovery manifests live at https://petrodb.ocortez.com.

• main — public production deployment
• stage — pre-production validation branch
