| contents | Data provenance has numerous applications in the context of data preparation pipelines. It can be used for debugging faulty pipelines, interpreting results, verifying fairness, and identifying data quality issues, which may affect the sources feeding the pipeline execution. In this paper, we present an indexing mechanism to efficiently capture and query pipeline provenance. Our solution leverages tensors to capture fine-grained provenance of data processing operations, using minimal memory. In addition to record-level lineage relationships, we provide finer granularity at the attribute level. This is achieved by augmenting tensors, which capture retrospective provenance, with prospective provenance information, drawing connections between input and output schemas of data processing operations. We demonstrate how these two types of provenance (retrospective and prospective) can be combined to answer a broad range of provenance queries efficiently, and show effectiveness through evaluation exercises using both real and synthetic data. |
