@duckdb Is there any guide for migrating to 1.0?

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. Since releasing the DuckLake manifesto in May 2025, we have seen massive adoption, with DuckLake deployed in production at multiple organizations, third-party clients supporting DuckLake, and even an upcoming O'Reilly book. DuckLake v1.0 ships many new features (inlining, partitioning, bucketing, type system improvements) and guarantees backwards-compatibility in the specification.

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: > 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. > "When I wrote the blog post about saying we had the 1,000x difference, I felt like, 'Oh, some people are gonna get angry,' but no one got angry. They're like, 'This is a real problem.' I even had someone say they were cheating with the architecture. That's the whole point: cheating with a better design," he told The Register. As bonus content, here's a snippet from our recent podcast where Mark Raasveldt and Pedro Holanda explain how data inlining works.

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/ducklake-…)! 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 on compaction and the challenge of long-running data lakes. Listen to the full conversation on YouTube or Spotify! Links in the 🧵

And don't forget about the DuckDB v1.5.2 announcement: duckdb.org/2026/04/13/ann…

DiDi, Design and Implementation of DuckDB Internals, treads on a path through selected internals of DuckDB. It cover topics such as memory management, indexing and optimization. duckdb.org/library/design…

TaDa, Tabular Database Systems, is a course on the fundamentals of relational database management systems. It teaches file formats (CSV, Parquet), columnar storage, memory management, and of course, SQL. duckdb.org/library/tabula…

Would you like to learn more about SQL or are you more interested in DuckDB's internals? Either way, you're in luck: Professor Torsten Grust of the University of Tübingen published two sets of lectures (almost 300 slides in total) along with their supplementary material.

DuckLake 1.0 will ship with the “data inlining” feature: small updates are staged in the catalog instead of creating many small files. In today's blog post, Pedro Holanda shows how DuckLake implements inlining and shows an almost 1000× speedup on certain operations. ducklake.select/2026/04/02/dat…

🎨 We rolled out a new section on our landing page this week! We hope it will help you explore the DuckDB ecosystem at a glance.

@cauchyzk Hello, unfortunately we have postponed the event indefinitely due to the current geopolitical instabilities and surging fuel prices, which would make travel quite expensive for speakers and attendees like. We'll host another DuckCon in Amsterdam in june!

@duckdb is this still happening?
