It seems that the leaderboard doesn't contain the results for all of the supported DBs (I was looking for the pgvector myself). The README.md contains a screenshot from local testing that's got more results included: https://github.com/zilliztech/VectorDBBench?tab=readme-ov-fi...

There are multiple vectordb available in the market, open source ones include Milvus, Qdrant, Weaviate etc. Cloud services include Zilliz Cloud (managed milvus), Qdrant Cloud, Weaviate Cloud etc. Try using a benchmark tool to evaluate them. Here is an open-source option for your reference: VectorDBBench (https://github.com/zilliztech/VectorDBBench)

In Qdrant, the Vector Search Database, raised $28M in a Series A round

We conducted benchmark tests on Elastic's queries per second (QPS) performance using datasets of 500,000 and 1 million vectors. Result was Zilliz is 13x and 22x faster, per number of vectors respectively. https://zilliz.com/blog/elasticsearch-cloud-vs-zilliz We also conducted a benchmark comparing Pgvector to both Milvus (open source) and Zilliz (managed, with a free tier option). When running the OSS Milvus on 2 CPUs and 8 GiB memory, Pgvector was found to be 5 times slower. You can check out the detailed performance charts at the bottom of this blog post: https://zilliz.com/blog/getting-started-pgvector-guide-devel... Feel free to explore our open-source benchmarking tool, which allows you to examine our methodology and even compare it with your vector database. https://github.com/zilliztech/VectorDBBench
