Real-world vector DB performance across the most popular providers
- MarekDlugos 10mo agoMy friends benchmarked managed vector databases under production-like conditions: high-throughput ingest, concurrent queries, filtering, and read–write mixed workloads. The post includes the methodology, the dataset, and the open-source tool they published for running the benchmarks.
- TechIsCool 10mo agoFeels like a sales pitch only due to the abstraction of Provider A,B,C vs actually naming the products. Guess thats what you get for a vendor blog.
- jerguslejko 10mo agoHey, author of the post here. We're actually not allowed to post head to head comparison with competitors and share their names, that's why :) Post contains the dataset, the tool and methodology how the data was collected, which hopefully gives confidence in fairness of the benchmark.
- yggdrasill501 10mo agoBest vector DB benchmark I have seen, solid benchmark design, but would be good if you would have shown who are the competitors in the graphs instead of anonymizing the numbers.
- jerguslejko 10mo agoHi, I'm Jergus, one of the founders of TopK. We cannot share the results publicly but happy to share privately (@jerguslejko on twitter, or jergus@topk.io)
- ms1472 10mo agoIs pgvector one of the systems you tested, or was it intentionally left out?
- jerguslejko 10mo agoWe didn’t include pgvector because we focused on managed services to keep things comparable — TopK is managed/serverless, so the fair match would be a managed Postgres. And pgvector just doesn’t really scale to the kinds of workloads we ran here.
