Adieu Apache Derby, Welcome DuckDB modern-sql.com/blog/2025-12...

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!

modern-sql.com now covers DuckDB.

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. If you need to look things up in the DuckDB documentation now, feel free to use our PDF: duckdb.github.io/duckdb-docs-...

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. developmentseed.org/blog/2025-10... @saadiqmohiuddin.bsky.social

I just launched github.com/tobilg/sql-w... It's a tiny (<10kb gzipped) wrapper around @duckdb.org WASM that can run queries interactively, and be embedded in plain HTML websites, as well as all other mayor frontend frameworks... It's an early version, feedback warmly appreciated!

📣 New blog post by @dtenwolde.bsky.social. 🕸️ In this post, we show how to use DuckDB and the DuckPGQ community extension to analyze financial data for fraudulent patterns with the SQL/PGQ graph syntax that's part of SQL:2023. 📖 Visit duckdb.org/2025/10/22/d... to read the post.

In a new guest blog post, Mark Harrison (Madhive) presents Frozen DuckLakes. These are read-only DuckLakes that only require object storage and are frozen in time. He shows a process for creating and freezing DuckLakes, and demonstrates their use and performance. 📖 ducklake.select/2025/10/24/f...

Beyond excited to share that I'm now working with DuckDB Labs! My first priority will be the DuckDB Rust client, which will receive a lot more love going forward. 🎉 🦆 ❤️

My #PyConUS talk is up! Tame data science file zoos with @duckdb.org! Read files of many shapes from any cloud, including your messiest CSVs. Then, organize all of your input tables, output tables, views, and relationships in one DuckDB file. No final_v3.csv! youtu.be/Yq-hxgysWLQ?...

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.

Ducklake is a really elegant solution to the data lake. Radically simple and completely open.

And the biggest winner is... DuckDB support for running queries on [remote] parquet files. This happens to be a basic building block of DuckLake and a few other alternative lake technologies

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.

Our USING KEY variant of recursive CTEs has landed in DuckDB 1.3 Formerly an off-the-beaten-path researchy idea, now available in a real off-the-shelf DBMS. Hooray! 🎉 duckdb.org/2025/05/23/u...

How do you detect if a subprocess errors? You might rely on error codes, great. And to be extra friendly you might also look for the substring `error` in the stdout stream, just to be sure. Welcome to MSBuild's take on error handling, and also my day. PR to @duckdb at github.com/duckdb/duckd...

I created a small DuckDB extension to choose file interactively using native file open dialogs. Now you can install this via Community Extensions repository! github.com/yutannihilat...

New sticker! @wasm.io has been great, see you all next year!

@ospencer.dev on webassembly GC as compiler target was pretty great, #wasmio

Super dense (and cool) from @lukewagner.name (from @fastly.com) on colorless async + threading. Thanks a lot, need to get the slides

Getting started at #wasmio

Excited to share my OS research at #wasmio25 in just 2 days! Be sure to stop by it will be great! 2025.wasm.io/sessions/sma...
