@duckdb.org is at it again 🚀. I'm really curious how this will be positioned against #Iceberg and @deltalakeoss.bsky.social. The ease of use and low barier of entry makes this very relevant IMHO 🦆🦆🦆 ducklake.select

Structured data is very sneaky! Just ask your favourite LLM. 1GB of text = ~250M tokens 1GB of structured trades = ~1B tokens That’s 4× the token cost for less semantic richness. Our new agentic friends have many capabilities, chewing structured data not among them. questdb.com/blog/why-ai-...
