The new open-source Vector Database Benchmark Tool is designed to help developers choose the ideal vector database for their projects. This tool enables users to measure performance across critical metrics and compare different options. Key features include flexibility, realistic workload simulation, interactive reports and visualization, and open-source community collaboration. VectorDBBench, written in Python, supports six vector databases: Milvus, Zilliz, Pinecone, Weaviate, Qdrant, and Elasticsearch. Users can download the tool from GitHub and install it using pip. The tool is actively maintained by a community of developers committed to improving its features and performance.
