How to choose Vector databases
- Choose by scale first: million-scale, ten-million-scale, hybrid search, and private deployment lead to different database choices.
- For RAG, prioritize filters, hybrid search, and update latency rather than only QPS.
- Managed services should be judged by cost structure and ops burden; self-hosted options by cluster complexity and recovery.
- Before launch, validate backups, tiering, and permission controls.
What matters first on Vector databases category pages?
Start with official access, pricing model, API support, open/closed status, and common use cases.
