Nanosecond Indexing of Graph Data With Hash Maps and VLists
Summary: Wait-free, multi-reader, single-writer graph indexing using hash maps and VLists; kill-9 durable, no reader-to-writer communication, enabling isolation and read scalability. Online updates preserve availability; 80 ns for small subgraph lookups, 12 ns per edge for materialization, 7 bytes/edge/index, ~1M online writes/sec. (summarized by gpt-5-nano on Feb 09 2026)
