About Milvus
Milvus is a high performance, cloud native vector database written in Go and C++, designed to power AI applications by efficiently storing, indexing, and searching large scale unstructured data such as text, images, and multi modal embeddings. It implements hardware accelerated approximate nearest neighbor (ANN) search using algorithms like HNSW, FAISS, and DiskANN, and supports both real time streaming updates and batch ingestion. Milvus lives in the GenAI infrastructure ecosystem, serving as the persistent storage and retrieval layer for embedding based workloads including RAG, recommendation, and image search.…
