To Not Miss the Forest for the Trees - A Holistic Approach for Explaining Missing Answers over Nested Data
Summary: Proposes a holistic, query-based explanation framework for missing answers over nested data, treating schema-modifying operators as potential causes. A heuristic uses multiple schema alternatives and iterative re-validation to prune non-contributing intermediates, enabling scalable Spark-based explanations that outperform prior work.
