Milvus

Cloud-native vector database built for billion-scale similarity search.

Milvus is an open-source vector database built for large-scale similarity search, with a cloud-native, distributed architecture that separates compute and storage. It supports multiple ANN index types (HNSW, IVF, DiskANN, and others), scalar filtering, and billion-scale vector workloads. It is widely used where very high-volume, production-grade vector retrieval is required.

What you'd build with it

  • Indexing and querying billions of embeddings for enterprise-scale RAG or semantic search
  • Tuning index types and parameters to balance recall, latency, and cost for large vector workloads
  • Backing image, audio, or multimodal similarity search at scale
