Worked on the duckdb/duckdb-go repository to implement Arrow Interface support for named arguments, allowing SQL query parameters to be specified by name rather than position. This feature enhanced query expressiveness and usability, particularly for workflows leveraging the Arrow data format. The development process involved Go programming and database management, with a focus on integrating named parameter support directly into the Arrow interface. Comprehensive test coverage was added to ensure correct handling of named arguments, reducing the risk of regressions and improving reliability. The work established a foundation for more flexible, parameter-driven queries and better compatibility with Arrow-based database operations.
