# Vector Database Research Notes (2024)
---
## Pinecone
- **Scalability:**
- Fully managed, cloud-native, designed for horizontal scaling to billions of vectors. Multi-tenant and multi-region support. [Manual verification recommended]
- **Performance:**
- Low-latency vector search (sub-100ms typical), optimized for high throughput. Uses proprietary indexing for fast ANN search. [Manual verification recommended]
- **Integration:**
- REST API, Python client, JavaScript client, integrations with LangChain, LlamaIndex, OpenAI, Hugging Face, and more.
- **Ecosystem:**
- Strong developer community, extensive documentation, tutorials, and ecosystem integrations (LangChain, OpenAI, etc.).
- **Pricing:**
- Usage-based pricing (per GB stored, per query, per index). Free tier available. [Manual verification recommended: https://www.pinecone.io/pricing/]
- **Operational Complexity:**
- Fully managed SaaS; no infrastructure management required. Simple API-based usage.
- **Deployment Options:**
- Cloud-only (AWS, GCP, Azure). No on-premises or self-hosted option as of 2024. [Manual verification recommended]
- **Security/Compliance:**
- SOC 2 Type II, GDPR, encryption at rest and in transit, role-based access control. [Manual verification recommended]

## Weaviate
- **Scalability:**
- Horizontally scalable, supports sharding and replication. Can handle billions of vectors. [Manual verification recommended]
- **Performance:**
- Real-time vector search, sub-100ms latency, supports hybrid (vector+keyword) search. Uses HNSW and other ANN algorithms.
- **Integration:**
- REST API, GraphQL API, Python/JavaScript/Go clients, integrations with LangChain, LlamaIndex, OpenAI, Hugging Face, and more.
- **Ecosystem:**
- Open-source, active community, plugin system, cloud and self-hosted options, strong documentation.
- **Pricing:**
- Open-source (free), managed cloud (usage-based pricing). [Manual verification recommended: https://weaviate.io/pricing]
- **Operational Complexity:**
- Managed cloud (Weaviate Cloud Service) or self-hosted (Docker, Kubernetes). Operational complexity depends on deployment mode.
- **Deployment Options:**
- Managed cloud, self-hosted (on-premises, any cloud, Docker, Kubernetes).
- **Security/Compliance:**
- Encryption in transit, authentication/authorization, GDPR, SOC 2 (cloud), RBAC. [Manual verification recommended]
