Duckdb

A code card on a yellow background showing DuckDB extensions in action: LOAD azure / postgres / postgres_scanner; ATTACH 'postgresql://...' AS postgres_db (TYPE POSTGRES); CREATE SECRET for Azure with credential_chain; then INSERT INTO postgres_db.users SELECT * FROM read_json_auto('az://users/*.json') JOIN role ON id = role.user_id.

My favourite DuckDB extensions

Three categories of DuckDB extensions I keep reaching for: cloud storage, semi-structured files, and external SQL databases.
