Whoever summoned this SQL abomination, I can’t tell if I should be impressed or horrified. Now I have to debug it…

ChatGPT: it's a recursive SQL simulation of the Fibonacci function, but instead of using simple recursion, it models the function as a concurrent task graph.

🎶 One of my favourite Dutch traditions is the #Top2000! Between Christmas and New Year, the 2000 most-voted songs are played non-stop. 🌟 They even share an Excel sheet with all the songs and their release years. With just three lines of #DuckDB, you can create a histogram of music history! 📊✨

Excited to speak at #DuckCon #6 in Amsterdam on Jan 31, 2025!🎉

I’ll share how #DuckDB unlocks graph analytics with SQL/PGQ from the SQL:2023 standard using the #DuckPGQ extension.

📍 Free to attend & livestreamed on YouTube!

🚀 Hope to see you there!

Honored to see our paper on #DuckPGQ mentioned by @andypavlo.bsky.social during the CWI lectures! With the introduction of SQL/PGQ, we argue that relational systems (like #DuckDB) can seamlessly handle graph data. Check out the paper here: www.cidrdb.org/cidr2023/pap...

Interesting discovery: there are roughly 9,000 accounts within 5 hops of those I currently follow! 🚀 (I assume I didn't mess up the data gathering)
Powered by @duckdb.org with the seamless #SQL/ #PGQ syntax supported in the #DuckPGQ extension. Amazing what you can uncover with the right tools!
