What is DuckDB?
DuckDB is an embeddable, in-process SQL OLAP database created by Mark Raasveldt and Hannes Mühleisen at CWI in Amsterdam, first released in 2019. It is free and MIT-licensed, governed in perpetuity by the nonprofit DuckDB Foundation, with DuckDB Labs (founded 2021, Amsterdam) leading development. It embeds directly into Python, R, Java, Node.js, Go, Rust and C/C++ applications and reads Parquet, CSV and JSON natively, without a separate database server.

Key capabilities
- Embeddable engine: A full SQL OLAP database that runs in-process, no server to deploy.
- Native file formats: Direct querying of Parquet, CSV and JSON files.
- Client libraries: Bindings for Python, R, Java, Node.js, Go, Rust and C/C++.
Embedded analytical (OLAP) database processing is the primary use case.
Shortlist DuckDB for local or embedded analytics, notebooks, ETL scripts, and small-to-medium OLAP workloads where standing up a separate database server is unnecessary overhead. It is not a networked multi-user server database by itself.
Confirm whether your workload truly fits a single-process embedded database or needs a networked multi-user server, before building around DuckDB's embedding model.
