DuckDB is an in-process analytical SQL database management system (OLAP) written in C++, designed to be fast, portable, and easy to embed. It offers a rich PostgreSQL-inspired SQL dialect, direct querying of CSV, JSON, Parquet, and Iceberg files, and client libraries for Python, R, Java, Node.js, Rust, Go, and WebAssembly.
Use cases
- run analytical SQL queries on local CSV and Parquet files
- embed an OLAP database in a Python data science workflow
- query pandas or R data frames with SQL
- process large datasets on a laptop without a database server
- read and write Apache Iceberg lakehouse tables
- run SQL in the browser via WebAssembly
- replace SQLite for analytics-heavy workloads
When to choose
- you need fast analytical (OLAP) queries over local or object-storage files
- you want an embedded database with no server to manage
- you need SQL over Parquet, CSV, JSON, or Iceberg data
- you want a rich SQL dialect with window functions and complex types
When to avoid
- you need a high-concurrency transactional (OLTP) database for a web app backend
- you need multi-client network access to a shared database server
- you need horizontal scaling across a cluster
