This blog discusses resource allocation for Milvus, an open-source vector database. It provides reference architectures based on specific numbers of users or requests per second (RPS) and different mixes of READ and WRITE operations. The article emphasizes the importance of understanding workload characteristics to determine Milvus' computational power and memory requirements. It also outlines a method for estimating resource needs, load testing, benchmarking, and concludes with recommendations for resource allocation based on data size and QPS requirements.
