Vector Quotient Filters: Overcoming the Time/Space Trade-Off in Filter Design
Summary: Vector Quotient Filter (VQF) uses power-of-two-choices hashing and SIMD for O(1) cost, stable across loads. Inserts ~2x Morton; lookups/deletes on par with cuckoo; thread-safe variant enables ~3x insertion throughput with four threads. (summarized by gpt-5-nano on Feb 09 2026)
