How does Milvus work?
Coordinator Services
Orchestrate load balancing and data management through coordinators, ensuring efficient data, query, and index management.
Access Layer
Handles external requests using stateless proxies to manage connections, perform verifications, and balance load.
Woker Nodes
Executes tasks as scalable pods by implementing coordinator commands, enabling dynamic adjustment for changing data, query, and indexing demands.
Storage Layer
Ensures data persistence through three components: meta stores, log brokers and object storage.
Why Milvus?
Milvus is a cloud-native, open-source vector database powering Zilliz.
Scale as needed
Handles billions of vectors through its distributed architecture, separating storage and compute. Its microservice design allows scaling specific functions, optimizing resource use as you grow.
Learn moreHigh Performance
Milvus offers diverse index types (HNSW, DiskANN, Quantization, Binary, etc.) and hardware-optimized designs for both CPU and GPU. This ensures fast vector retrieval with high recall across various use cases.
BenchmarkFull Development Lifecycle Support
Milvus provides three deployment models with a unified API: Milvus Lite for prototyping, Standalone for testing and small-scale production, and Distributed for large-scale production. This allows developers to scale their applications from initial testing to full deployment without rewriting code.
Learn moreFeature Rich
Supports multiple search types (top-K & Range ANN, sparse & dense, multi-vector, grouping), metadata filtering, and multi-tenancy. It includes admin tools and integrates with various AI tools and models.
