LLM-R2: A Large Language Model Enhanced Rule-based Rewrite System for Boosting Query Efficiency

arXiv:2404.12872v1 Announce Type: cross
Abstract: Query rewrite, which aims to generate more efficient queries by altering a SQL query's structure without changing the query result, has been an important research problem. In order to maintain equivalence between the rewritten query and the original one during rewriting, traditional query rewrite methods always rewrite the queries following certain rewrite rules. However, some problems still remain. Firstly, existing methods of finding the optimal choice or sequence of rewrite rules are still limited and …
