DuckLake is an integrated data lake and catalog format. DuckLake delivers advanced data lake features without traditional lakehouse complexity by using Parquet files and your SQL database. It's an open, standalone format from the DuckDB team.

@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 🦆🦆🦆

Why AI needs a database | QuestDB AI won't replace databases — but it will transform how we use them. This article explores why AI and databases work better together, breaking down LLM tokenization, real-time data access, and…

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.

Interesting move and a new study programme from @vut.cz. Right target audience and decent course composition, the price is IMHO also very acceptable. Although some legislature/law centric courses should be mandatory. Good direction overall!
