Milvus: The Cloud-Native Vector Database Powering AI Search at Scale
Discover Milvus, the leading open-source cloud-native vector database with 45k+ GitHub stars for RAG and semantic search.
What Is Milvus?
Milvus is a high-performance, cloud-native vector database purpose-built for scalable approximate nearest neighbor (ANN) search. With over 45,000 GitHub stars and an active open-source community, it has become the de facto standard for vector storage and retrieval in modern AI applications. Written in Go and C++, Milvus delivers blazing-fast similarity search across billions of vectors while maintaining enterprise-grade reliability and scalability.
Why Vector Databases Matter for AI
Large Language Models (LLMs) and embedding models generate vector representations of text, images, and audio. These vectors encode semantic meaning — but without a specialized database, searching through millions of vectors is impractically slow. Milvus solves this by providing efficient indexing algorithms (IVF, HNSW, DiskANN) that enable sub-millisecond similarity searches across massive vector collections. This is the foundation of Retrieval-Augmented Generation (RAG), semantic search, recommendation systems, and multimodal AI pipelines.
Key Features
Multiple Index Types
Milvus supports IVF, HNSW, DiskANN, and GPU-powered indexes, allowing you to trade off between accuracy, speed, and memory. DiskANN enables billion-scale vector search on standard SSDs.
Cloud-Native Architecture
Built for Kubernetes, Milvus separates storage and compute into independently scalable components, ideal for production deployments with varying query loads.
Hybrid Search
Milvus combines vector similarity with scalar filtering and metadata queries. Find products similar to an image where price is under $50 in one query.
GPU Acceleration
NVIDIA GPU acceleration delivers up to 10x throughput improvement over CPU-only search.
Quick Start with Docker
