DILI: A Distribution-Driven Learned Index

Summary: DILI: distribution-driven learned-index tree using cheap linear models at nodes; internal nodes equally partition ranges to guarantee correct leaf routing, leaves use ML to predict record positions. Built bottom-up then top-down to tailor fanouts to local distributions, balancing leaf count vs height, with efficient insert/delete and adaptive restructuring; outperforms prior learned indexes.
