DBMS Fitting: Why should we learn what we already know?

Summary: Critiques end-to-end DNN replacements for DBMS components as data-hungry and opaque; proposes leveraging differentiable programming to fit components using known algorithmic structure rather than learning behavior from scratch. Case study: fitted cost model for query plans with initial promising results. (summarized by gpt-5-mini on Feb 09 2026)
