Worked on the influxdata/iceberg-rust repository to deliver unsigned integer support within the ArrowSchemaConverter, addressing a key gap in schema conversion between Arrow and Iceberg. Focused on safe type casting, the implementation enabled correct handling of UInt8, UInt16, and UInt32 by mapping them to signed Iceberg types, while introducing explicit error guidance for UInt64 to prevent unsafe conversions. This approach improved data compatibility and reduced the risk of silent data corruption. The work involved data engineering, error handling, and schema conversion using Rust, with comprehensive tests and validation to ensure reliability across new code paths and datatype scenarios.
