This repository provides a SQLAlchemy dialect for DuckDB, enabling DuckDB to be used as a database backend within SQLAlchemy's ORM and Core APIs. It maps DuckDB's type system to SQLAlchemy types, handles connection management (including in-memory and file-based databases), supports reflection (schema introspection), and integrates with DuckDB extensions. The dialect is built on top of the PostgreSQL psycopg2 dialect, customizing it for DuckDB's capabilities and limitations. The source code is well-structured, extensively tested, and actively maintained, with support for DuckDB versions 0.5.0 through 1.2.2 and SQLAlchemy 1.3 through 2.0.35.
