Don't think it's widely known or understood, but Ducklake doesn't require duckdb: it's just a (good) data lake spec that works in duckdb.
There's a cool alternate rust/datafusion ecosystem initiative going on at https://github.com/datafusion-contrib/datafusion-ducklake, and think the Quack protocol opens up a lot of cool possibilities too.
If you need an idea for what do do with ducklake: recommend throwing all of your agent traces in it.
It's alright, it's pretty alpha software. On v1.5.4, catalog filtered counts are broken, afaik. I went to main/v2 to fix it, and then the SQL parser in duckdb v2 is 10x slower, which was another wrench in the gears. It's been a bit of a pain tbh
Yep, they made the spec 1.0 but it isn’t 1.0 software. Browse the bugs before use.
When it works well it’s really nice. And it beats handrolling a multi level parquet store.

But "Duckpond" was right there!
DuckDB is the best thing world got since 1990s.

Why program greenfield in C++? I know "made with rust" is a meme but seriously, why not a memory safe language in 2026?
DuckDB has been around since 2018. Naturally its offspring use C++.
