Updatable Learned Indexes Meet Disk-Resident DBMS - From Evaluations to Design Choices

Summary: Disk-resident updatable learned indexes vs B+-tree; four SOTA methods implemented. Findings: B+-tree robust on disk; learned indexes beat it only on select workloads; design principles: lower height, lean structures, faster scans, compact storage. (summarized by gpt-5-nano on Feb 09 2026)
