Hyper: A High-Performance and Memory-Efficient Learned Index via Hybrid Construction

Summary: Hyper: hybrid learned index construction to break the usual performance/memory trade-off in dynamic settings. Bottom-up leaves + top-down internals yield concurrent write support and strong speedups with drastically lower memory than prior learned indexes. (summarized by gpt-5.4-mini on May 24 2026)
