pg_duckdb extends PostgreSQL with DuckDB, a columnar-vectorized analytics engine. It allows users to execute analytical queries directly within PostgreSQL using DuckDB's engine. This integration eliminates the need for data exports and accelerates data-intensive applications by leveraging DuckDB's performance benefits. It's built in collaboration with Hydra and MotherDuck.
pg_duckdb enables running existing SQL analytics queries without code changes. It offers seamless integration with data lakes like Parquet, CSV, Iceberg, and Delta Lake, allowing querying data directly from these sources. The project's design focuses on minimal disruption to existing PostgreSQL workflows, promoting easy adoption. It supports integration with MotherDuck for cloud-based analytics.
- Query Acceleration: Leverage DuckDB's vectorized execution for faster analytical queries.
- Data Lake Integration: Read and write data from Parquet, CSV, Iceberg, and Delta Lake formats.
- SQL Compatibility: Existing SQL queries work with minimal or no modification.
- MotherDuck Integration: Extend compute power to cloud-based analytics infrastructure.
- Simple Setup: Easy deployment through Docker and manual installation.
- Extensibility: Supports extensions for enhanced functionality and data format support.
- Developer Focused: Provides a clear path for contribution and easy integration into existing workflows.
pg_duckdb is an active project with regular releases and ongoing development. The project has a growing community and active issue tracking. Documentation is comprehensive covering core functionality, configuration, and advanced features. Recent commits indicate active maintenance and feature development, suggesting good reliability.
pg_duckdb benefits data analysts and application developers who need to perform high-performance analytics on PostgreSQL data or data stored in data lakes.
