Dataset: 2026 Vector Databases, Semantic Search & Hybrid RAG Infrastructure Benchmark (50 Stacks)
Engineered for AI engineers, CTOs, and agent architects designing scalable RAG retrieval pipelines:
• Architectures: Purpose-built cloud engines, disk-first NVMe/S3 columnar storage, in-memory real-time stores, PostgreSQL relational extensions, and edge serverless DBs
• Index Algorithms: HNSW, DiskANN, IVF-PQ, ScaNN, SIMD-accelerated flat indexes, and dynamic quantization (PQ/SQ/BQ)
• Hybrid Search: Dense + sparse BM25/SPLADE, Reciprocal Rank Fusion (RRF), cross-encoder reranking (Cohere, Jina, BGE), and SQL metadata filtering
• 50 Stacks Evaluated: Pinecone, Qdrant, Weaviate, Milvus, LanceDB, Chroma, Turbopuffer, pgvector, pgvectorscale, Supabase Vector, Neon, Vespa, Marqo, ClickHouse, SingleStore, MongoDB Atlas Vector, Astra DB, Couchbase Capella, Neo4j GraphRAG, SurrealDB, Redis Vector, Aerospike, Upstash Vector, Cloudflare Vectorize, AWS OpenSearch Serverless, Azure Cosmos DB, Google Vertex AI Vector Search, Snowflake Cortex, Databricks, DuckDB vss, Elasticsearch, OpenSearch, Algolia NeuralSearch, Meilisearch, Typesense, Quickwit, USearch, Faiss, Annoy, Hnswlib, Convex, CockroachDB, TiDB, Cohere Rerank, Voyage AI, Jina AI, Mixedbread, Baseten, BAAI BGE, Deep Lake
5-Row Sample Preview:
1. Pinecone: Serverless decoupled | Dense+Sparse BM25/SPLADE | p99 <15ms @ 100M+
2. Qdrant: Rust memory-mapped | Dense+Sparse BGE-M3 + RRF | p99 <4ms single-node
3. Weaviate: Go modular AI-native | BM25 + Vector Relative Fusion | p99 <10ms
4. Milvus: C++/Go distributed | Multi-vector + GPU RAFT | p99 <5ms @ 100M+
5. LanceDB: Lance columnar on S3/NVMe | Tantivy BM25 + Vector RRF | p99 <8ms disk
