milvus — High-Performance, Cloud-Native Vector Database for Scalable Vector ANN Search

Overview

Milvus is a high-performance, cloud-native vector database designed for scalable vector Approximate Nearest Neighbor (ANN) search. It is built to efficiently organize and search vast amounts of unstructured data, such as text, images, and multi-modal information. Written in Go and C++, Milvus leverages hardware acceleration for CPU/GPU to achieve best-in-class vector search performance.

Key Features

Hardware acceleration for CPU/GPU
Fully-distributed and K8s-native architecture for horizontal scaling
Standalone mode for single machine deployment
Milvus Lite for quickstart in Python with pip install
Support for real-time streaming updates

Use Cases

AI applications requiring efficient organization and search of unstructured data
Applications needing to handle tens of thousands of search queries on billions of vectors
Use cases benefiting from real-time data updates and high scalability

Advantages

High vector search performance due to hardware acceleration
Scalability to handle large-scale data and query volumes
Flexibility with both standalone and distributed deployment options
Easy integration with Python applications through pymilvus SDK

Limitations / Considerations

May require significant resources for large-scale deployments
Learning curve for new users unfamiliar with vector databases or ANN search
Potentially complex setup and configuration for distributed environments

Faiss: A library for efficient similarity search and clustering of dense vectors, differs in that it is a library rather than a standalone database.
Elasticsearch: A search engine based on the Lucene library, which offers full-text search but is not specialized in vector search like Milvus.
Annoy: A library for approximate nearest neighbors written in C++, differs in that it is not a database and lacks the distributed capabilities of Milvus.
