Optimizing Queries across Diverse Data Sources

Summary: Garlic’s optimizer extends rule-based optimization to heterogeneous data integration, combining generic middleware rules with wrapper-supplied source capabilities. This modular design supports extensibility, incremental rule implementation, and effective cross-source plan generation. (summarized by gpt-5.6-luna on Jul 24 2026)
