A new research paper provides a comprehensive empirical evaluation of seven prominent vector database systems, including FAISS, Qdrant, Milvus, Weaviate, Chroma, pgvector, and LanceDB. The study, which analyzed over 4 million vectors across six diverse datasets, measured retrieval quality, query latency, throughput, and resource utilization. Key findings indicate that FAISS offers the highest single-node throughput, Weaviate provides excellent recall, Qdrant delivers the best latency among full databases, and LanceDB excels in faster index construction at the cost of retrieval quality. The research aims to offer system-selection guidelines for practitioners and has released its benchmarking framework as open-source. AI
IMPACT Provides practitioners with data-driven guidelines for selecting vector databases, crucial for AI applications like RAG and semantic search.
