🏷️ skill
Overview
Open-source vector database for scalable similarity search
Pros
- ✓ 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
Cons
- ✗ 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
Key Features
- 🔍Billion-scale Similarity Search: Handle vector similarity queries across billions of embeddings with millisecond latency using optimized index structures like IVF, HNSW, and DiskANN.
- 🔀Hybrid Scalar-Vector Filtering: Combine vector similarity with traditional metadata filters in a single query, enabling pre and post-filtering on structured fields alongside vector searches.
- ☸️Kubernetes-native Deployment: Deploy on Kubernetes with automatic scaling, load balancing, and high availability built in. Scales compute and storage independently for optimal resource utilization.
- 📊Multi-index Type Support: Choose from IVF, HNSW, DiskANN, and other specialized indexing algorithms optimized for different accuracy-speed tradeoffs and dataset sizes.
- ⚙️Production Vector Operations: Built-in batch operations, transaction support, and schema management designed specifically for production-scale vector database requirements and reliability.
