It's an interesting project, but the discussion on HN looks weird. It gets brought up every few weeks[1] and everyone just spams comments with messages about how "fast" it is.

DuckDB is fast for some specific workloads. If you use it for most other things, it is at least an order of magnitude slower than SQLite. It also has some limitations in terms of what SQL it will currently run (e.g. I immediately ran into an issue with recursive queries). That will probably get better with time.

[1] If you search HN for "sqlite" and "duckdb" you get 4,310 hits and 2,398 hits respectively. That's a very heavy skew, considering SQLite is everywhere and had been around for a quarter century, while DuckDB effectively appeared on the scene two years ago.
