Hourglass: An Adaptive Range Filter with Lightweight Hybrid Encoding

Summary: Hourglass is an adaptive range filter that splits keys into semi-sorted cuckoo-filtered prefixes and hybrid-encoded suffixes to boost space efficiency and handle skew/adversarial queries. It adds fingerprint-updating adaptivity and correlation-aware space allocation, yielding 9.8–35.4× lower FPR. (summarized by gpt-5-mini on Feb 11 2026)
