CM-Explorer: Dissecting Data Ingestion Problems
Summary: CM-Explorer: system for disentangling correlated violated conditional unit tests over conditional metrics (CMs) to surface minimal subrelations (tuples) that explain ingestion errors. Uses a graph explorer (correlation visualization), relation explorer (tuple browsing) and history explorer (temporal diagnostics) to help stewards find the most relevant tests.
