Milvus Review 2026

Open-source vector database for scalable similarity search

⭐ 46k+ stars 📜 Apache-2.0 🏷️ skill

Overview

Open-source vector database for scalable similarity search

✓ Purpose-built for production vector similarity search at billion-scale
✓ Supports multiple index types (IVF, HNSW, DiskANN) and hybrid scalar+vector filtering
✓ Cloud-native with Kubernetes deployment, auto-scaling, and high availability
✓ Active development with Zilliz providing enterprise support

✗ Heavier operational footprint than simpler alternatives — runs as a distributed system with multiple components
✗ Overkill for small-scale applications (< 1M vectors) where Chroma or Qdrant are simpler
✗ Steeper learning curve for configuration compared to embedded vector stores
