Key Insights:

1. Many database back up their data in a sqlite database. Some even push vectors into sqlite, but others store vectors in their own format.

2. Qdrant has higher client connection and index initialization time that can shadow its benefit on fast and accurate vector search.

This article contains a lot of inaccuracies.

Based on your statements, like

> Qdrant stores both the vectors and the metadata in a sqlite database.

It looks like you have benchmarked local mode of qdrant. It doesn't even use vector indexes and is not designed for any kind of production usage.

For anyone reading this article, I urge you to do your own benchmarks and not rely on claims that do not have open source code attached to them to replicate the results

Hi Andrey. Thanks for your feedback. We should have better emphasized that we are benchmarking Qdrant in local mode. We have updated the post to clarify that Qdrant is being evaluated in local mode. We plan to next evaluate the server mode.

We went with the local mode as several Python AI apps are using Qdrant in that mode based on the suggestion here: https://qdrant.tech/documentation/quick-start/.

We also believe in open-sourced benchmark code. Please find the code here: https://github.com/jiashenC/vectordb-benchmark-and-optimize/....
