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/...

We are happy to announce DuckDB v1.4.3 LTS, our latest patch release. Along with bugfixes, this release ships native extensions and Python support for Windows ARM64. Head to duckdb.org/2025/12/09/a... for the announcement blog post and installation instructions.

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...

We took Canada’s Spatial Access Measures dataset (big, clunky CSVs) → turned it into a single GeoParquet file. Add DuckDB-WASM + deck.gl & you get - instant queries - smooth maps - no backend Public data, but actually usable. developmentseed.org/blog/2025-10... @saadiqmohiuddin.bsky.social

pg_lake just went open source! (Apache 2.0) pg_lake is a set of extensions (from Crunchy Data Warehouse) that add comprehensive Iceberg support and data lake access to Postgres, with @duckdb.org transparently integrated into the query engine. Announcement blog: www.snowflake.com/en/engineeri...

After trying @duckdb.org with terabytes of parquet I'm hardly going back for data exploration to anything else. Hell, I'm now spawning DuckDB for analyzing even .csv and .json files due to how ergonomic its SQL is.

We published a new deep dive by Laurens Kuiper, who recently redesigned DuckDB's sort. One data point: ordering the TPC-H SF100 lineitem table with the memory limit set to 30 GB is 3× faster in DuckDB v1.4 than in v1.3. Read more at duckdb.org/2025/09/24/s...

Stretching DuckDB w/ Common Crawl, ~1.7B rows, ~300 parquet files. ~2-3s for single-column aggregations, ~2-3 mins to SUMMARIZE the data, peaking at ~12-14GB memory usage. Not exactly real-time, but the fact you can do this on a laptop with no server setups or Spark pipelines is still amazing.

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...
