The Architecture Handbook for Milvus Vector Database

Yudong Cai is a senior software engineer with over 20 years of experience in large-scale system development. As one of the founding members of the Milvus project, he helped build Milvus from the ground up and has been involved in the development and iteration of every version since its initial open-source release. His key contributions include delivering the first production-grade Range Search implementation, as well as the refactoring of the entire Milvus configuration system, alongside the design and implementation of numerous other critical features. He is also the original developer and key maintainer of Knowhere, Milvus’ core vector computation engine, where he designed its architecture to support multiple hardware acceleration frameworks and a wide range of vector search algorithms.

Jeremy Zhu is a quality assurance engineer at Zilliz, focused on ensuring the robustness and high performance of the Milvus vector database. His core responsibilities include designing comprehensive test cases, developing automated system test pipelines for diverse scenarios, and executing rigorous stress, recovery, and performance testing. Jeremy possesses deep expertise in chaos engineering, distributed systems testing, and test automation frameworks, playing a key role in maintaining Milvus’ high-quality standards.

Xuan Yang is a senior software engineer at Zilliz in China, passionate about designing high-performance, scalable distributed database systems. As a core Milvus contributor, she architected the DataNode module, implemented the compaction process, and led the L0 segment design. She is the primary maintainer of PyMilvus, the official Python SDK, and VectorDBBench, an open-source benchmarking framework for vector databases. She cares deeply about system stability and performance and is always eager to collaborate with the community to push the boundaries of large-scale AI and vector data infrastructure.

Bang Fu is a senior software engineer at Zilliz. With extensive experience in both Go and Python, he has actively contributed to the development of several key features for Milvus, including permission verification, request interception, incremental synchronization, and serverless metering functionalities. He is also interested in AI technology and led the development of the GPTCache project, which focuses on caching LLM responses to improve speed and reduce costs. In addition, he has participated in the development of the DeepSearcher project.
