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.

www.whova.com (and app on mobile). Event „management“ service used by all the major DB conferences for some years now. By default spammy, spammy, spammy (notifications, e-mail) to a comical degree.

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 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.

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! 🎉

USING KEY in Recursive CTEs

Recursive CTEs in SQL allow for powerful iterative queries like graph traversals but can be memory-intensive and slow due to repeated row accumulation. DuckDB’s new USING KEY feature addresses this by...

Hehe… 😅

Kudos for your work on making GTFS data readily available in DuckDB, by the way. Absolutely fabulous sample data for teaching purposes. Very motivating for students to touch data that immediately relates to their everyday life (public transport, say).

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

DuckDB @duckdb.org · Mar 12

DuckDB got a local UI. Thanks to our friends at MotherDuck, you can now interact with your DuckDB database through an interactive notebook, running on localhost. Read the announcement blog post at duckdb.org/2025/03/12/d...
