Worked on the apache/iceberg-go repository to deliver a new ReplaceDataFiles capability, enabling direct replacement of Parquet data files without requiring schema validation scans. This approach reduced commit-time validation overhead and addressed issues related to incomplete Parquet reads during file replacement, supporting faster and more reliable ingestion workflows, including multipart uploads. The feature was co-authored to accelerate vendor-code adoption and improve ingestion robustness for users managing their own Parquet files. Leveraged Go for backend development, with a focus on data engineering and parquet file handling, and integrated AWS Glue to streamline data ingestion and metadata placement within the project.
