제목 Achieving Low-Latency Graph-Based Vector Search via Aligning Best-First Search Algorithm with SSD
궁금했던 점 How can graph ANN search hide SSD latency without sacrificing search accuracy?
해본 것 PipeANN relaxes strict compute-I/O ordering and pipelines graph expansion with SSD requests while preserving best-first search quality.
당시 조건 Venue: OSDI. Year: 2025.

Best-first graph traversal serializes node expansion and SSD I/O, leaving compute and storage underlapped.

Verification: official USENIX page and abstract; confidence=high.

실제 결과 workloads=billion-scale ANN datasets; baselines=in-memory Vamana and DiskANN; metrics=query latency and accuracy; results=1.14–2.02x in-memory Vamana latency; 35% of DiskANN latency; no accuracy loss
왜 그랬는지 A controlled relaxation of traversal order exposes enough parallel I/O to approach DRAM search latency.
다음에 기억할 것 Pipeline dependent storage lookups by admitting bounded reordering that preserves the algorithmic invariant.
언제 맞는지 SSD-resident graph ANN indexes at billion-vector scale.

Limits: Reported relation to in-memory Vamana is still slower; gains depend on graph/search and SSD characteristics.
