Frequently Asked Questions

What is DuckDB used for?

DuckDB is used for fast analytical queries on local data files like CSV and Parquet. It is commonly used by data analysts and engineers for data exploration and processing.

Is DuckDB free to use?

Yes, DuckDB is completely open-source and free. There are no licensing costs or usage-based pricing.

How is DuckDB different from SQLite?

DuckDB is optimized for analytical (OLAP) workloads, while SQLite is designed for transactional (OLTP) use cases. DuckDB is better for large-scale data analysis.

Can DuckDB handle large datasets?

Yes, DuckDB can efficiently process large datasets using columnar storage and vectorized execution. However, it is limited to single-node processing.

Do I need a server to use DuckDB?

No, DuckDB runs directly inside your application or environment. There is no need to set up or manage a database server.
