During March 2026, Marco Nastasi developed a recursive Python dictionary to SQL struct converter for the lancedb/lancedb repository, enabling safe and scalable updates to struct-typed columns. He implemented a handler that translates nested Python dictionaries into DataFusion’s named_struct SQL syntax, integrating this logic with the table.update method to support complex updates involving nested data models, lists, nulls, and various scalar types. Marco used Python, SQL, and DataFusion to ensure compatibility with DataFusion 52.1, and wrote comprehensive unit tests for flat and nested structures. This work deepened the update capabilities for struct columns, though CI integration tests remain pending.
