Worked on the delta-io/delta-rs repository to enhance Change Data Feed (CDF) read performance and correctness by refining partition pruning logic. Focused on pruning partitions before parquet scans, improving error handling to ensure query correctness, and refactoring code for maintainability. Addressed edge cases involving constant partition predicates and empty schema references, strengthening integration tests to cover a wide range of predicate forms. Used Rust for backend development, emphasizing data engineering and performance optimization. The work resulted in more efficient data processing, robust error handling, and maintainable code, directly improving the reliability and speed of CDF reads in production environments.
