Guided automated learning for query workload re-optimization
Summary: GALO automates fixing costly query plans with offline learning of recurring patterns, yielding RDF/SPARQL knowledge base of remedies. Third-tier re-optimizer after cost-based optimization, enabling cross-workload generalization and performance insight on TPC-DS/IBM datasets. (summarized by gpt-5-nano on Feb 09 2026)
