ANN-Benchmarks

Standardized benchmark for QPS/latency/recall tests on ANN libraries using datasets like SIFT1M and Deep1B to compare throughput and accuracy. Features metrics for build time, memory usage across HNSW, FAISS, ScaNN. Used for vector DB index selection during development; contrasts with BigANN billion-scale competitions by focusing on million-scale library performance vs full-system custom benchmarks.
