Hands-On with VDBBench: Benchmarking Vector Databases for POCs That Match Production

This post introduces VDBBench 1.0, an open-source tool for benchmarking vector databases. It details the importance of using custom datasets and production-like workloads for POCs, contrasting this with outdated benchmark datasets. The post provides a comprehensive guide to installing and using VDBBench, including data preparation steps with automated conversion scripts for CSV/NPY to Parquet format, ground truth computation using FAISS, and configuration via a web interface. It highlights key metrics like P95/P99 latency, sustained throughput, and recall accuracy.
