Vector Database

Database optimised for storing and querying high-dimensional embedding vectors.

Definition

Vector databases index dense embeddings via approximate-nearest-neighbour algorithms (HNSW, IVF, ScaNN) and serve top-k similarity queries with low latency. They are the storage layer for RAG, recommendation systems and any embedding-driven workload.

Common use cases

  • RAG
  • Semantic search
  • Recommendations
