Milvus: Large-Scale Open-Source Vector Database

Milvus: Large-Scale Open-Source Vector Database

Milvus is a high-performance, cloud-native open-source vector database built for scalable similarity search and AI applications, supporting billion-scale vector data with millisecond-level query latency.

Features

Purpose-built for massive-scale similarity search with support for billions of vectors, delivering consistent millisecond-level latency through advanced indexing algorithms and hardware-aware optimizations.

Combined vector similarity search with scalar filtering, full-text search, and metadata-based queries for precise, multi-modal retrieval across structured and unstructured data.

Multiple Index Types

Extensive index support including IVF, HNSW, DiskANN, GPU-accelerated indices, and sparse vector indices for optimizing search performance across different data scales and hardware configurations.

Cloud-Native Architecture

Disaggregated storage and compute architecture with support for Kubernetes-native deployment, horizontal scaling, and multi-tenancy for production-grade vector search infrastructure.

Multi-Vector & Sparse Support

Native support for dense vectors, sparse vectors, and multi-vector fields in a single collection, enabling advanced retrieval strategies like hybrid dense-sparse search.

Data Management

Full CRUD operations on vector data with support for partitioning, dynamic schema, time-travel queries, and consistent data management at scale.
