MCTuner: Spatial Decomposition-Enhanced Database Tuning via LLM-Guided Exploration
Summary: MCTuner uses a Mixture-of-Experts of LLMs to pinpoint performance‑critical knobs and avoid ineffective regions in high‑dimensional config spaces. Its recursive spatial decomposition runs Bayesian optimization on hierarchical subspaces, yielding up to 19.2% gains and 1.4× faster discovery versus SOTA.
