DAGSmith: Dependency-Aware Rewriting for dbt-Style SQL Pipelines

DAGSmith is introduced, to the best of the authors' knowledge the first holistic dependency-aware source-to-source rewriting system for SQL pipeline DAGs and enables dependency-edge simplification, non-local semantic reuse, downstream-aware pruning, pipeline-aware work placement, rewrite-materialization co-optimization, and frequency-aware optimization.
