Choosing the Right Vector Database for RAG and AI Applications

Short summary

Vector databases are critical infrastructure for RAG and semantic search applications, enabling efficient storage and retrieval of high-dimensional embeddings at scale. This guide evaluates databases across performance, scalability, cost, and developer experience dimensions. Selection depends on your specific application requirements, expected scale, and infrastructure constraints.

  • Vector databases store and retrieve high-dimensional embeddings for RAG and semantic search
  • Key evaluation criteria: performance, scalability, cost, developer experience
  • Choice should align with application scale, requirements, and deployment environment
