Frequently Asked Questions
- Weaviate achieves 791 QPS at 2ms latency on the nytimes-256 dataset per the 2023 VectorView benchmark, outperforming Qdrant at 326 QPS and Pinecone at 150 QPS on equivalent pod configurations. For on-chain AI workloads with burst traffic from multiple agent queries, Weaviate's throughput ceiling is highest when running self-hosted with tuned HNSW parameters. Qdrant closes the gap under filtered-search conditions where pre-filter HNSW gives it a structural advantage over Weaviate's post-filter architecture.
- HNSW (Hierarchical Navigable Small World) builds a layered proximity graph enabling sub-10ms ANN search at 95-99 percent recall on datasets up to 50 million vectors (ann-benchmarks.com, 2023), but requires storing all vectors in RAM. IVF-PQ (Inverted File with Product Quantization) clusters vectors into partitions and compresses each cluster with quantization codes, cutting memory consumption by 2-4x at a 1-8 percent recall penalty (Weaviate docs, 2023). For production RAG on DeFi protocol documentation with datasets under 5M vectors, HNSW is the correct default. Above 50M vectors or under strict memory budgets, enabling HNSW-PQ in Weaviate or scalar quantization in Qdrant provides the best recall-per-GB ratio.
- Pinecone is a fully managed cloud service with data residency in AWS us-east-1 by default. For on-chain AI applications subject to GDPR Article 25 data minimisation requirements or EU AI Act high-risk system obligations, teams must review Pinecone's data processing agreements and confirm EU-region availability. Self-hosted Qdrant or Weaviate deployments on infrastructure inside the EU provide stronger data residency guarantees and allow teams to implement privacy-by-design controls at the storage layer, making them the preferred architecture for regulated European DeFi or RWA applications.
