If you are into Iceberg or DuckDB, this is a major step: you can access existing Iceberg datasets, while they are appended on or updated by other users (possibly they can also be clicking buttons in a browser).
This has been very fun, was looking forward to be able to properly share, thanks flock!

You can now query Iceberg catalogs with DuckDB – from the convenience of your browser.
In our latest blog post, we break down how DuckDB's WebAssembly client makes this possible with zero setup and showcase it in action using Amazon S3 Tables.

Today's Cloudflare outage has affected the DuckDB documentation site. While it seems to be mostly recovered now, it will take some time until everything stabilizes.

We took Canada’s Spatial Access Measures dataset (big, clunky CSVs) → turned it into a single GeoParquet file.
Add DuckDB-WASM + deck.gl & you get
- instant queries
- smooth maps
- no backend
Public data, but actually usable.

Yesterday DuckDB Labs announced DuckLake, a new Open data and catalog format. Here is a bit about why it is so awesome, how it solves some key problems with existing technologies, and why we're excited to host it in the cloud at MotherDuck.
S3 isn’t a database. But what if your lakehouse finally acted like one?
@jrdntgn.bsky.social shares why the current generation of lakehouse formats like Iceberg and Delta Lake might be missing the point—and how DuckLake, a new table format, changes the game.

Ducklake is a really elegant solution to the data lake. Radically simple and completely open.
Today we're launching DuckLake, an integrated data lake and catalog format powered by SQL. DuckLake unlocks next-generation data warehousing where compute is local, consistency central, and storage scales till infinity. ducklake is an open standard and we implemented it in the "ducklake" extension.
