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 🧵.

ORDER BY Has Come a Long Way modern-sql.com/blog/2026-05... The ORDER BY clause is surely one of the best-known SQL clauses. Yet there are a number of common misunderstandings that are worth clearing up. For that, the article walks you through the evolution of the ORDER BY clause the SQL standard.

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

ISTANBUL, WIR KOMMEN! ❤️‍🔥

I've been working on organizing our next DuckCon for the past three months. The program is finally out and I think we have a really strong lineup, featuring speakers from ETH Zürich, Spotify, MariaDB, the Merck Group, Snowflake, Foursquare, and more. Join us in Amsterdam on June 24!

The program for DuckCon #7 is out! Here's the gist: – State of the Duck: DuckLake v1.0 + a super-secret new feature – Six regular talks (incl. one from Spotify) – Six lightning talks (incl. Toyota Gazoo WRT) – Drinks & snacks and time to socialize 🧵 Full program and registration link in the thread

Flattered that the good FP folks put up with me as a DB guy. Thank you for the chat, @kosmikus.bsky.social and @sperbsen.bsky.social. What a fun hour to spend!

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!

We released DuckDB v1.5! This release comes with a “friendly CLI” client, a new (opt-in) PEG parser, support for VARIANT types and many lakehouse features. It also ships a new network stack, a reworked geospatial extension, Azure writes and an ODBC scanner. Read more at duckdb.org/2026/03/09/a...

🗓️ This year, we came up with new merchandise: the 2026 Friendly DuckDB calendar, which has a SQL feature for every month along with art inspired by the feature. ⬇️ If you were lucky to get one at our events, that's great! :) If not, you can still grab the PDF at blobs.duckdb.org/merch/duckdb...

🌏 We are happy to announce the first DuckCon in the APAC region: DuckCon #7 will take place in the National Gallery Singapore on 2026-05-05. 🗳️ Registration and the Call for Talks are open! Submit your proposals until 2026-03-18. ➡️ duckdb.org/events/2026/...

🏗️ The DuckDB team is working hard on delivering DuckDB v1.5. 🌃 While the official release is next week, you can already give it a quick test using the nightly builds available at duckdb.org/install/prev... If you encounter any issues, let us know! 🐛💬

🦆 ↔️ 🦀 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...

🎞️ The slide decks and talk recordings of last Friday's developer meeting are out! duckdb.org/events/2026/...

📆 The DuckDB Developer Meeting in Amsterdam starts tomorrow! We'll have a deep-dive extension development workshop in the morning and four exciting talks in the afternoon. 🎟️ Last chance to register at duckdb.org/events/2026/...

Please help us publicize TEAL: Tools for Educational Activities in Logic, a workshop associated w/ FLoC26. We have a novel design, focused on demos, discussion, and generally high-quality interaction rather than weak papers. See full details on our site! teal.cs.brown.edu/floc2026/

We are going to hold the first DuckDB Developer Meeting in two weeks in Amsterdam! On the day of the meeting, DuckDB Community Extensions development champion Rusty Conover will also give a workshop on DuckDB extension development. Check out the programme and sign up at duckdb.org/events/2026/...

I've posted my latest recap of the world of databases: www.cs.cmu.edu/~pavlo/blog/... All the hot topics from the last year: • More Postgres action! • MCP for everyone! • MongoDB gets litigious with FerretDB! • File formats! • Market movements! • The richest person in the history of the world!

The second derivative of smile is indifference.

🏛️ We launched the DuckDB Library: a curated collection of papers, podcasts, talks and books about DuckDB. 📚 We already have a collection of almost one hundred entities. The thumbnails show whether a piece is from the DuckDB team (yellow) or from others (purple). ➡️ duckdb.org/library/

On the south stand again! #scf

modern-sql.com now covers DuckDB.

SQL's recursive common table expressions (CTEs) have a questionable reputation: verbose, awkward to read, inefficient to evaluate, ungrokkable semantics, ripe with arbitrary syntactic restrictions, and basically stale for 25 years now (since their advent in SQL:1999). Ugh.

Here's what we've got in store for you! 🎓 E1: Torsten Grust (@teggy.org) (University of Tübingen) - Recursive Common Table Expressions (CTEs) Demystified 🧨 E2: Abigail Kim (@abigalekim.bsky.social) (Carnegie Mellon University) - Anarchy in the Database (deep dive into DBMS Extensibility)

What if a database could be your game engine? During parental leave @lukasvogel.bsky.social built DOOMQL: A multiplayer DOOM-like where everything (rendering, game loop, state) runs in pure SQL on CedarDB. It's fast, ridiculous, and surprisingly elegant. Full write-up: cedardb.com/blog/doomql

Vol:18 No:12 → Democratize MATCH_RECOGNIZE! 👥 Authors: Louisa Lambrecht, Tim Findling, Samuel Heid, Marcel Knüdeler, Torsten Grust 📄 PDF: https://www.vldb.org/pvldb/vol18/p5251-lambrecht.pdf

I don‘t know about you. But Whova is such a PITA.

🔬 We are hosting the first “DuckDB in Science” meetup in London on September 4, co-located with VLDB 2025. 🔍 We'll have two deep-dive presentations from DuckDB's developers and four lightning talks from community members. 📍 For details and registration, see duckdb.org/events/2025/...

The Call for the 2026 International Symposium on Functional and Logic Programming (FLOPS) is open - the symposium will be May 26-28 in Akita, Japan. Deadline for the CfP is Dec 8 (abstracts) / Dec 16 (submissions). Send us your best on the best of both worlds! functional-logic.org/events/flops...

Pleased to announce that the third edition of my PL book, PLAI, is finally available on paper! Same price as it's been for 20 years (-:. Also made it available on Kindle EPUB, and a few other options. (Always free options, of course.) Enjoy! www.plai.org

This is a briljant feature! I have actually used it to solve a challenge I faced for a customer, and it was a lot quicker than a more traditional SQL-based solution. To be fair, it was slower than an equivalent algorithmic solution. Anyway thanks @teggy.org and @duckdb.org for contributing this!

We'll host the DuckDB Berlin Meetup in two weeks with talks from Amine Mhedhbi, Marcin Rudolf and David Justen. If you're based in Berlin or will be attending SIGMOD 2025, register at www.meetup.com/duckdb/event... and drop by!

📢 We are hosting a DuckDB meetup in Berlin during the week of the SIGMOD conference. 📍 The meetup will take place on June 26 (Thursday) south of the Tiergarten and will feature talks by Amine Mhedhbi, David Justen and dltHub! 📝 If you plan to attend, please register at duckdb.org/events/2025/...

We have a guest blog post by researchers at the University of Tübingen. 🎓 In this deep dive, Björn Bamberg and Torsten Grust (@teggy.org) introduce “USING KEY”, which allows defining a key to reduce the memory usage of recursive common table expressions. Read the post at duckdb.org/2025/05/23/u...

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...

𝑬𝒖𝒓𝒐𝒑𝒂 wir kommen! ❤️

We teamed up with the Disseminate: The Computer Science Research Podcast to launch a new series called DuckDB in Research. In the first episode, show host Jack Waudby talks to Till Döhmen about DuckDQ, a Python library for data quality checks in ML pipelines: open.spotify.com/episode/2a0b...

So thrilled the DuckDB UI is out to the world! Read the post, but wanted to also share a couple small design details we thought about in thread
