Milvus is a highly scalable, open-source vector database specifically built to power AI and machine learning applications.

Unlike traditional databases (like MySQL or Oracle) that use exact-match text queries, Milvus uses semantic similarity search. When you query Milvus, it finds data whose vector embeddings are closest in mathematical space to your query, allowing applications to find “meaning” or “concepts” rather than just exact words
