Our built-in SQL cells are powered by duckdb, which makes it possible to execute blazingly fast queries against Python dataframes as well as external databases like SQLite and Postgres.
DuckDB is the core, embedded SQL engine we use to power MotherDuck. DuckDB clients connect to MotherDuck by changing their database name. Dual execution processes queries locally, in cloud or both.
We use DuckDB WebAssembly as the core of Universal SQL and it has made it possible to deliver incredibly fast, interactive apps. The DuckDB team and community are phenomenal.
