Neo: A Learned Query Optimizer

Summary: Neo (Neural Optimizer) uses deep neural networks to generate query execution plans, offering a learning-based alternative to hand-tuned optimizers. Bootstrapped from traditional optimizers, it learns from live queries, adapts to data patterns, is robust to estimation errors, and can match or surpass state-of-the-art engines.
