Sphinx: A Succinct Perfect Hash Index for x86
Summary: Sphinx reengineers succinct perfect hashing for x86, combining rank/select-friendly encoding with metadata for near-instant common-slot decoding. Its expandable, parallel design halves query/update latency and memory versus prior ~4-bit-per-key indexes. (summarized by gpt-5.6-luna on Jul 24 2026)
