Some big news: @ducklabs.com is joining AWS, with the move expected to complete by early September. Our team will stay together in Amsterdam, with more resources to take DuckDB, DuckLake and Quack further - while the open-source Duck Stack remains free under MIT license ducklabs.com/news/2026/08...

DuckLabs to Join AWS, Projects to Remain Open Source

DuckLabs provides services around the DuckDB in-process OLAP data management system directly from its main developers.

DuckDB Table Functions in Java 🦆 ☕ The DuckDB #Java client registers table functions written in pure Java, exposing any Java-accessible data source as a SQL table. That turns #DuckDB into a single-node query engine for heterogeneous joins across remote systems and local files, with no export step.

Congratulations to Dr. Laurens Kuiper for defending his PhD thesis with **cum laude** distinction! https://www.ru.nl/en/about-us/events/analytical-query-processing-beyond-main-memory #DuckDB

Analytical Query Processing Beyond Main Memory | Radboud University

This PhD thesis studies how relational database systems can process queries whose temporary intermediate data exceed main memory without suffering abrupt performance collapse.

Traditional databases were "sold on the golf course" — to purchasing departments, not developers. @hannes.muehleisen.org on how that blind spot created the gap between pandas and Spark that @duckdb.org walked right into. Episode link below

Missed out on attending #DuckCon in Amsterdam or via the livestream? 🦆📺 Don’t worry, you can still catch up with all the news and roadmap announcements from “The State of the Duck” keynote right here: Video: www.youtube.com/watch?v=iFPK... Slides: blobs.duckdb.org/events/duckc... #DuckDB

🦆 There's only one week to go until DuckCon #7 in Amsterdam! We are all hyped to meet the flock and learn about the latest cool use cases from our community. As always, the event will feature the “State of the Duck” talk from DuckDB's co-creators.

Today, we are releasing DuckDB v1.4.5 and v1.5.4. Yes, we know – these version numbers can be a bit confusing! That's why we wrote two blog posts this time. The thread helps you pick the right one 🧵

What's new in DuckDB and how does DuckDB fit into old shell scripts? These are topics that our DevRel Gábor covered at Ubuntu Summit 2026. His talk explained three aspects of DuckDB: a command-line tool, a portable database, and a client-server database. duckdb.org/library/duck...

#DuckDB has announced Quack - a new remote protocol over HTTP that enables multiple DuckDB instances to connect to and work with the same database across a network. Quack brings client-server capabilities to a database that has traditionally been local and embedded. 🔗 bit.ly/4o22y0i #InfoQ #AI

I want to explain to those who haven't used #duckdb with #Rstats that sometimes DuckDB isn't the difference between fast and slow but between possible and not.

DuckDB Labs becomes DuckLabs. We ended up working on more than DuckDB, i.e., DuckLake and most recently, Quack. It was time to change the company name to reflect this. Nothing else changes – read our blog post for more details. ducklabs.com/news/2026/05...

This week we released an ADBC driver for Quack, @duckdb.org’s new native client-server protocol. Now you can query remote DuckDB servers using the same ADBC interface you already use for local DuckDB across 7+ languages—no third-party server extensions required. columnar.tech/blog/quack-a...

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 🧵.

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

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.

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...
