DILI: A Distribution-Driven Learned Index

Summary: DILI builds a distribution-driven learned index with linear models and adaptive, locality-aware fanouts, yielding perfect internal-node routing and model-predicted leaf positions. It supports efficient dynamic updates by restructuring as distributions change, outperforming prior learned indexes. (summarized by gpt-5.6-luna on Jul 24 2026)
