OpenDuck is an open-source implementation of MotherDuck's distributed DuckDB architecture, enabling queries to split transparently across local machines and cloud infrastructure via an attach-based protocol. The system uses append-only layered storage with PostgreSQL metadata and object storage backends, supporting concurrent readers with serialized writes. It provides both native Python bindings and DuckDB protocol compatibility.
