Worked on the rapid7/iceberg repository to address data correctness in Iceberg Spark changelog queries, focusing on stability and traceability. Delivered a targeted bug fix in Java and Spark that ensures changelog queries return empty results when the start timestamp is after the latest snapshot, preventing invalid data retrieval. Enhanced the solution with comprehensive regression tests, using robust testing practices to validate that empty scans occur in these scenarios. The work improved test coverage and future release confidence by ensuring changelog queries behave as expected. All changes were documented with descriptive commit messages to support traceability and maintainability within the codebase.
