Worked on enhancing path handling logic in the apache/iceberg repository, focusing on the RewriteTablePathUtil component. Addressed edge-case behavior in the relativize method to ensure correct handling when paths matched the prefix, and improved the newPath method for scenarios involving source-prefix paths. Expanded unit test coverage to validate these edge cases, reducing the risk of errors during table rewrite operations and improving data path correctness. Utilized Java for implementation, applying skills in path manipulation and comprehensive unit testing. The work delivered a targeted core feature that increased reliability and data integrity for path resolution within the table rewrite workflow.
