Worked on the apache/iceberg-python repository to deliver a focused data model cleanup, specifically deprecating the snapshot-id field in SetStatisticsUpdate and consolidating its usage under statistics.snapshot-id. This change simplified the backend data model, reduced ambiguity, and improved data integrity for statistics updates. The approach involved updating validation logic and comprehensive unit tests to ensure the new model’s reliability and maintainability. Using Python and leveraging skills in backend development and data modeling, the work aligned with ongoing API simplification efforts and provided a clear migration path for downstream users, supporting long-term stability without introducing new bugs during the period.
