Today, we are releasing DuckDB v1.5.3. This is not an ordinary patch release – it packs many new features for the Quack client-server protocol, Quack support for DuckLake, and big updates for AWS, HTTPS and Iceberg. Check out our blog post about all these changes and improvements – link in the 🧵.

Im Interview erklärt Hannes Mühleisen, CEO von DuckDB Labs, wie sich die DuckDB von SQLite for Analytics zu einem universellen Datenwerkzeug entwickelt hat. #Datenbanken

This Tuesday, Hannes announced Quack, our new protocol that turns DuckDB into a client-server database. Watch his talk, recorded at the AI Council, where he explained how Quack works in practice, what stack it's built on, how it performs, and what our long-term ambitions are. youtu.be/L_lttD-d1wc

Today we are revealing the Next Big Thing for DuckDB: Quack, a protocol that turns DuckDB into a client-server database. True to DuckDB's philosophy, Quack is simple and fast. Setting it up takes seconds, and it works for both bulk operations and small write transactions. 🔗 duckdb.org/quack

The Delta and Unity Catalog extensions in DuckDB have shed their experimental labels! Today's blog post by Ben Fleis presents there features: ✍️ Write Delta tables 🤝 Multi-writer access with concurrency control through UC ⏪ Time travel queries on Delta tables Read more: duckdb.org/2026/05/07/d...

"We have a database and we're not afraid of using it." How DuckDB tackled the small changes problem in lakehouse design. www.theregister.com/2026/04/16/d...

I've been working on this over the last few months and in my opinion it is just beyond cool. Grammar of graphics for SQL users!

We are hosting the next edition of our community conference, DuckCon, in Amsterdam on June 24. The registration is already open and you can submit your talk proposals until next Wednesday. Looking forward to your submissions and seeing the flock in the summer!

The Register published a report on DuckLake v1.0 and cited our recent post: > In a blog post accompanying the 1.0 launch, Pedro Holanda, DuckDB Labs principal engineer, said the company's benchmark shows 926× faster queries and 105× faster ingestion when compared to Iceberg, the open table format.

DuckDB uses RDBMS to attack classic 'small changes' problem in lakehouses

We heard that a specification looks more serious if it's served as a PDF. Well, you can read the DuckLake documentation as a PDF now (blobs.duckdb.org/docs/ducklak...)! This document covers both the specification and the DuckDB extension's usage.

Yesterday, we released DuckLake v1.0 and also published a podcast where Pedro Holanda and Mark Raasveldt talk about the DuckLake, going into quite some technical details. Listen to the episode at ducklake.select/media/duckla...

Don't forget about the DuckDB v1.5.2 announcement: duckdb.org/2026/04/13/a...

We are happy to release DuckLake v1.0, a production-ready lakehouse format specification. Its reference implementation, the ducklake DuckDB extension, is available as of today in DuckDB v1.5.2. For more details, read the announcement blog post: ducklake.select/2026/04/13/d...

You have to really love something to write a book about it. DuckLake makes PB-scale lakehouses simple: Postgres, Object Storage, DuckDB, & 6 lines of SQL. Chapter 1 of the @oreilly.bsky.social book I'm co-authoring just dropped - download for free at this link! motherduck.com/lp/ducklake-...

🦆 ↔️ 🦀 DuckDB Labs is looking for a Rust engineer to join our team in Amsterdam. 📝 See the details and application page at duckdblabs.com/jobs/rust_en...

@hannes.muehleisen.org I LOOOOVE DuckDB so much that I am presenting a "DuckDB 101" session at datatuneconf.com on March 7

Tired of digging through gov databases for H1B wage data? I built OpenH1B.org to make it easy. 500k records, DuckDB/Parquet tech, 200+ QPS speed. Search by ZIP for official DOL levels. https://openh1b.org #h1b #career #data #python

DuckDB was added to the wall of fame of CWI, next to Dijkstra’s shortest path algorithm, the Atlantic Crossing of the Internet & the creation of Python On the occasion of our 80th (really!) bday Congrats to @hannes.muehleisen.org & @markraasveldt.bsky.social @duckdb.org @cwi-amsterdam.bsky.social

holy moly! great caesar's ghost! The DuckDB C extension template makes writing DuckDB extensions SO MUCH EASIER/FASTER. /me *is about to run amok making extensions*

I love this idea: duckdb.org/community_ex.... It translates dplyr syntax _inside_ of duckdb so you can mix it with regular SQL

I’m absolutely delighted to see @hannes.muehleisen.org talk for the first time in person. He is somehow using duckdb for his slides (of course), and talking about the joy of sql… if properly implemented.

🖥️ In today's “What's on your desk?” episode, @hannes.muehleisen.org tests the MOREFINE M700S computer. This computer ships with a Loongson processor that comes with its own CPU architecture. Despite this, DuckDB runs on it quite easily. See the details in the blog post. ➡️ duckdb.org/2026/01/06/d...

Yeay!! I wrote a very opinionated list of tips for working with DuckDB in R! Hope others find it useful. github.com/eriksquires/...

Hey folks! I built a Canadian trade database to practice what I'm learning about DuckDB. The database includes all Canadian imports and exports from 1988 to present as per Statistics Canada. Here's a blog post I wrote with more details: joshpersi.github.io/blog/posts/0... #rstats #duckdb

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. 👉 duckdb.org/2025/12/16/i...

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!

Found this fun bug in #Google Maps. The Austin airport jumps away and back quite far just by zooming...

In seven weeks, we will host the first DuckDB Developer Meeting in Amsterdam. We have four exciting talks lined up on building extensions in DuckDB, encryption in DuckDB, DuckPL and GizmoEdge. For more details and the registration links, please head to duckdb.org/events/2026/...

This is the most exciting time ever to be working in data, and I'm not talking about AI. 3 years ago, I wrote a database-centric guide in my book for analyzing the full 92 million record 1910 Census. Now, with #rstats and @duckdb? Analyze those 92 million rows in seconds.

modern-sql.com now covers DuckDB.

In DuckDB v1.4.2, we shipped a number of features and improvements to the DuckDB-Iceberg extension: insert, update, and delete statements are all supported now. Read Tom Ebergen's new article on these features at duckdb.org/2025/11/28/i...

DuckDB v1.4 introduced the much-requested feature of database encryption. In our new blog post, @ccfelius.bsky.social and @hannes.muehleisen.org explain how the encryption works under the hood: duckdb.org/2025/11/19/e...

I’m thrilled to share that my new book (Spatial Data Management with DuckDB) is now published! 🎉 At 430 pages, this book provides a practical, hands-on guide to scalable geospatial analytics and visualization using DuckDB. All code examples are open-source and freely available on GitHub.

🚀 We released DuckDB v1.4.2, the second patch release of our LTS edition. 🔎 We are shipping new Iceberg features, improved logger/profiler integration and several bugfixes. The new DuckDB version can also read and write Vortex files. 📖 For more details, read duckdb.org/2025/11/12/a...

This profile in ‘Significance’ on DuckDB co-founder Hannes Mühleisen is quite interesting, and has helpful insights about data quality and the changing meaning of “big data.” Also some good professional advice in here for statisticians. academic.oup.com/jrssig/artic...
