Key Features
Performance
- Rust-powered — written in Rust for maximum speed and memory safety
- Billion-scale — handles billions of vectors with quantization and sharding
- HNSW indexing — fast approximate nearest neighbor search
Advanced Search
- Hybrid search — combine dense vectors with sparse vectors (BM25-style)
- Payload filtering — filter results by metadata alongside vector similarity
- Multi-vector — store multiple vectors per point (e.g., title + content embeddings)
Production Features
- Multi-tenancy — isolate data per customer within one collection
- Snapshots — backup and restore collections
- Horizontal scaling — distributed mode with sharding and replication
- REST + gRPC APIs
Integrations
LangChain, LlamaIndex, Haystack, Spring AI, AutoGen, CrewAI, and 50+ frameworks.
