An Overview of Milvus – An Open-Source Vector Database Engine

Milvus is an open-source vector database engine that enables efficient storage, management, and search of large-scale vector data. It is suitable for a wide range of machine learning, data mining, and artificial intelligence applications. Here we provide an overview of Milvus and how it works.

Milvus is optimized for the storage of high-dimensional vectors. It stores these vectors in a structured format, allowing for efficient storage and retrieval. You need to specify the dimensionality of your vectors when creating or inserting data into the database.

To speed up vector similarity searches, Milvus supports various indexing methods and algorithms. These indexes are data structures that help organize the vector data to improve search performance. Common indexing methods include Hierarchical Navigable Small World (HNSW) and Annoy.

Milvus is designed to be highly scalable. It can be deployed on clusters of machines, and the data can be partitioned and distributed across these machines. This scalability allows Milvus to handle large datasets with millions or billions of vectors.

Milvus provides an API that allows you to perform complex similarity search queries on your vector data. You can search for vectors similar to a query vector or find similar vectors within a collection. The Milvus engine handles the search efficiently by using the chosen indexing method.

Milvus can take advantage of GPUs (Graphics Processing Units) to accelerate vector search operations. This is especially beneficial for large-scale similarity searches, as GPUs can perform vector operations faster than CPUs.

Milvus can be integrated with various programming languages and frameworks, making it accessible for developers working with different technologies. This integration allows you to build applications that leverage the power of vector databases for tasks like recommendation systems, image retrieval, and more.

Milvus is open-source, meaning the source code is freely available for developers to use and modify. This open-source nature has contributed to its adoption and popularity in the machine learning and AI communities.

The general workflow in Milvus involves creating or importing a dataset of high-dimensional vectors, choosing an indexing method that suits your dataset and query requirements, and using the API to perform similarity searches or other vector-based operations. By utilizing indexing and optionally GPU acceleration, Milvus aims to provide efficient and scalable solutions for working with large-scale vector data in machine learning and AI applications.
