There tend to be a lot of heuristics involved when deciding which optimizations to apply and in which order, so there's plenty of room to apply some machine learning. Whether LLMs are the right approach is a separate question. In SQL optimization, the problem is a bit trickier (IMO) because compilation is in the query path. One successful approach I know of is Bao: https://arxiv.org/abs/2004.03814 https://arxiv.org/abs/2004.03814
