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-...

3 options: - Keep the amazing name Duck Lake - Get rid of that pesky space and go full DuckLake - Towny McTownFace

Today's Future Data Systems Seminar Speaker: Jordan Tigani (@jrdntgn.bsky.social) will present how @motherduck.com supports modern workloads with DuckLake. Zoom talk open to public at 4:30pm ET. YouTube video available after: db.cs.cmu.edu/events/futur...

Are you streaming into your Lakehouse? Traditional formats suffered with the “many small files” problem — OLAP engines merge them reactively with long jobs. ⏳ DuckLake takes a proactive path: Data Inlining + async flush to parquet while always keeping data queryable ⚡

when I say “storage is cheaper now” this is what I mean topicpartition.io/definitions/...

How many 6 year old databases get 3x faster sorting??? When it was already world-class??? Amazing stuff from DuckDB!

🚀 We released version 0.3 of the DuckLake specification and the DuckDB ducklake extension today. It includes interoperability with Iceberg, support for geometry types and more. Check the announcement blog for more details ducklake.select/2025/09/17/d...

I've been leading the data infrastructure efforts at my job (I used to work as a Data Engineer in big tech) and the stack we've landed on is so enjoyable to work with. @dagster.io - Orchestration @duckdb.org - Database @motherduck.com - Data Warehouse/storage DBT - Data modeling

Laurens Kuiper from @duckdb.org presented DuckDB's new memory assignment policy to run multi-join pipelines out-of-core with gracious performance degradation when join hash tables increasingly do not fit in RAM. A well-attended and -delivered talk! paper: vldb.org/pvldb/vol18/p2748-kuiper.pdf

Bad news: we had to postpone today's episode. Good news: @tylerhillery.com has a great blog entry that features some of the Oxide and Friends back catalog you might have missed!

"GROUP BY ALL" was added to Oracle! Friendlier SQL to the rescue!

🔥 DuckDB is featured in @fireship.bsky.social's “100 seconds” series: 🚀 www.youtube.com/watch?v=uHm6...

DuckDB may have an adorable mascot, but this is serious DB tech! As a larger-than-memory system, data durability is critical!

I went through DuckDB's WAL, and it does everything I was asking for in my blog post: 1. Per record checksum 2. Explicit error on checksum failure 3. Configurable behavior 4. Partial recovery 5. Safe truncation of the WAL only when WAL contents are checkpointed

We just published a deep dive on spatial joins in DuckDB by @maxxen.bsky.social. In this blog post, Max explains how spatial joins evolved in DuckDB and how the current operator harnesses R-Trees. Read the full post at duckdb.org/2025/08/08/s...

#SD25 online continues tomorrow! Join Cpt. @hannes.muehleisen.org for his talk on DuckLake Aug 4 at 10am PT / 1pm ET / 7pm CET www.youtube.com/watch?v=YQEU...

We launched huge Mega and Giga instances this week, and the Small Data conference will celebrate that now we can all make big data feel small! Crunching large datasets in the year 2025 should not be complicated. Join us to learn from some of the best in the biz!

@duckdb-gsheets.com now supports ducklake!

HUGE day for MotherDuck! These giant Mega and Giga instances make even big data feel small. Easily crunch through even your toughest data problems!

Every once in a while, you can take a query from an hour to a couple of seconds... What a feeling! Gotta let it marinate for a minute until jumping into the next one...

📢 DuckLake 0.2 is out! We added new features to the specification and improved support in the DuckDB ducklake extension. See the announcement blog post at duckdb.org/2025/07/04/d....

A DuckLake reader for PySpark in ~30 lines of code. Despite looking simple, still partitions work across Spark nodes. Zero external dependencies, just the DuckDB JDBC driver. Try that with your favorite lakehouse technology :-)

The #dataBS (Data Behind the Scenes) Conference Call for speakers is out! We're gonna do this!! All online, single track, free to attend. Come talk about your messy experiences doing data stuff. At work, personal projects, whatever. A space to commiserate about nerdy things! bit.ly/dataBSconf-cfs

Fully managed DuckLake comes to MotherDuck! Well, what is DuckLake? A new faster, easier data lakehouse format! We can manage your data, metadata, and compute, or you can bring your own object store bucket or even bring your own compute!

New blog post by Petrica Leuca: Discovering DuckDB Use Cases via GitHub > In this post, we use the GitHub API to find repositories that mention DuckDB, then use DuckDB itself to parse and query the results efficiently with SQL. duckdb.org/2025/06/27/d...

If you need a mask to enforce the law, you don’t deserve a badge. Federal agents are snatching people off the streets—faces covered, names hidden. This isn’t safety. It’s secrecy. It’s not America. adamkinzinger.substack.com/p/why-are-fe...

Hot take: DuckLake makes Iceberg look like Hadoop.

Curious to know more about DuckLake? Next Tuesday, DuckDB co-creator @hannes.muehleisen.org will talk with @motherduck.com CEO @jrdntgn.bsky.social about DuckLake and the future of open table formats. 📆 June 17 (Tuesday), 8:00 PDT / 17:00 CEST ✍️ Register at lu.ma/mt9f8xh1?tk=...

I did a talk about the main project I've been working on for the past year: "pg_duckdb". So if you're curious what that is, give it a watch: youtu.be/0kc-W5o0tcg #posetteconf

We released DuckDB 1.0.0 a little over a year ago with a small easter egg. Since then, no one reported finding it, so we're revealing it: the hash of the DuckDB 1.0.0 binary starts with the duck emoji: 0x1f986 = 🦆.

Want 10x faster dashboards using @duckdb.org , Apache Parquet, or DuckLake? Sort multiple columns approximately using Morton (Z-order) and Hilbert encodings! Check out real world benchmarks & all the SQL you need! Even measure your dataset sortedness. Down with the loading spinners!

DuckLake is an exciting new approach for the data lakehouse! It is fundamentally simpler, yet faster and more feature rich. That is a powerful combination. HOW? By abstracting the complexity in the perfect place: a database. A technology purpose built for safe concurrency. Let's add it everywhere!

DuckDB flips lakehouse model with bring-your-own compute and metadata RDBMS

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.

Meet the elegant, modern evolution of the Data Lakehouse - DuckLake! Store data in files on object storage and metadata in ~any SQL database! Full ACID transactions across tables and far faster and easier!

New post by Pedro Holanda, Ian Cook, Dewey Dunnington and Bryce Mecum: Arrow IPC Support in DuckDB This blog post introduces the new arrow community extension, which boosts interoperability by allowing to consume/produce data through the Arrow IPC Serialization Format. duckdb.org/2025/05/23/a...

DuckDB v1.3.0 “Ossivalis” is out and it packs a ton of new features, fixes and optimizations. See the announcement blog post: duckdb.org/2025/05/21/a...

This is tomorrow! lu.ma/xakrgxqu

If you know DuckDB, you know we don't often tease new features. This is BIG.

Did you know a 2012 Macbook Pro can analyze a TB of data? Imagine what your laptop can do!!

#PyconUS was amazing, of course! Thanks to the organizers! Tons of great chats with old and new friends. It feels like the data science community is really exploring new tabular data tech. Good news - @DuckDB is not all-or-nothing! Sprinkle it in to fix CPU/RAM issues, or for the messiest CSVs!
