Selecting the right vector database is a foundational decision in RAG system design. We benchmark Qdrant, PGVector (PostgreSQL extension), and Pinecone across indexing speed, query latency, and self-hosted cloud costs.
Summary Benchmark Findings
- **Qdrant**: Best overall performance for complex payload filtering and self-hosted Rust efficiency.
- **PGVector**: Ideal for existing PostgreSQL setups, simplifying data architecture with transactional consistency.
- **Pinecone**: Fully managed serverless vector database for zero-ops cloud deployments.
