Public Apache Iceberg datasets via a REST catalog

In plain words

This project provides free public Apache Iceberg datasets hosted on a production-grade REST catalog, allowing developers to query data immediately using Spark, Trino, or Flink without setting up their own infrastructure. It includes datasets like NYC Taxi data and requires only a Google Cloud Project ID for authentication. The service eliminates the typical barriers to experimenting with Iceberg, enabling users to run queries directly against the REST endpoint without configuring storage buckets or ingesting data beforehand.

The promise of the Open Data Lakehouse is simple: your data should not be locked into a single engine. It should be accessible, interoperable, and built on open standards. Today, we are taking a major step forward in making that promise a reality for developers, data engineers, and researchers everywhere. We are thrilled to announce the availability of high-quality Public Datasets served via the Apache Iceberg REST Catalog .

In the maker’s words, at launch

Hi HN, I’m one of the creators of this project. We noticed that while many developers want to experiment with Apache Iceberg the "entry cost" is often high. You usually have to set up your own storage buckets, configure a catalog (like Hive), and ingest data before you can even run a single SELECT statement. We…

  SwiftLake – Lightweight SQL Engine for Iceberg Tables2025 · github.com · ▲6

  At Arcesium, we needed a way to run SQL-driven CRUD operations, manage slowly-changing dimensions, and handle schema evolution on our cloud data lakes—without the overhead of spinning up distributed clusters or relying on vendor-managed query services. That’s why we built SwiftLake, a lightweight open-source library that brings Apache Iceberg and DuckDB together: - Lightweight & cluster-free: Runs as a single Java service with embedded DuckDB—no distributed infra required. - Full CRUD and SCD1/SCD2 support: Reads, inserts/appends, updates, deletes, and merges with ACID guarantees.…

  This is a small, framework-agnostic JavaScript/TypeScript client for the Apache Iceberg REST Catalog. It is good for managing the catalog (eg: managing tables), and it's MIT licensed. The goals: - Generic: Works with any Iceberg REST Catalog implementation, not tied to any specific vendor - Minimal: Thin HTTP wrapper over the official REST API, no engine-specific logic - Type-safe: First-class TypeScript support with strongly-typed request/response models - Fetch-based: Uses native fetch API with support for custom implementations - Universal: Targets Node 20+ and modern browsers…

  isometric.nyc – giant isometric pixel art map of NYC▲1,325

  Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
