    About this tool

    Overview

    VDBBench is an open-source vector database benchmarking tool designed for comparing and evaluating vector databases. It's designed for users who require high-performance data storage and retrieval systems.

    Database Support

    Supports testing of:

    • Milvus
    • Zilliz Cloud
    • Elasticsearch
    • Qdrant Cloud
    • Weaviate Cloud
    • PgVector

    Key Features

    Real-World Testing

    VDBBench is the only benchmark tool that tests vector databases across the complete spectrum of production-critical scenarios:

    • Static collection tests
    • Filtering scenarios
    • Streaming cases

    Comparison Capabilities

    Offers the ability to select and compare results from multiple tests simultaneously, making it easy to understand relative performance across different vector databases.

    Modern Datasets

    VDBBench uses vectors generated from state-of-the-art embedding models that power today's AI applications, moving beyond legacy datasets like SIFT and GloVe.

    Benchmark Metrics

    VDBBench measures:

    • p99 serial search latency
    • Maximum concurrent QPS at 90% data capacity
    • Performance while insertion workload remains active
