R-Bot: An LLM-based Query Rewrite System
Summary: R-Bot uses LLMs for SQL rewriting while mitigating hallucinations via multi-source rewrite evidence and hybrid structural-semantic retrieval. Its iterative, self-reflective rule selection outperforms prior methods and reduces latency in Huawei/customer deployments. (summarized by gpt-5.6-luna on Jul 24 2026)
