Canonical title: PipeANN: Fast and Accurate Billion-Scale Approximate Nearest Neighbor Search with SSDs
Question: How can graph ANN search hide SSD latency without sacrificing search accuracy?
Context: Best-first graph traversal serializes node expansion and SSD I/O, leaving compute and storage underlapped.
Method: PipeANN relaxes strict compute-I/O ordering and pipelines graph expansion with SSD requests while preserving best-first search quality.
Evaluation: 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
Interpretation: A controlled relaxation of traversal order exposes enough parallel I/O to approach DRAM search latency.
Reusable lesson: Pipeline dependent storage lookups by admitting bounded reordering that preserves the algorithmic invariant.
Applicability: 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.
