bobvanluijt··on Vector databases: analyzing the trade-offs
> Is there some weird toxic subculture in the vector database space

(I work for Weaviate)

Unfortunately, some players in the space (who are on this list) are cheating and playing an unfair game. I guess that this comes with a rapidly growing space.

I hope we can all quickly go back to focussing on our respective communities and educating the market (together) on the awesome things one can do with vector DBs.

This is false

Based on what?

This is really cool, especially with enterprises moving to using LLMs in production. These K8s tools make a lot of sense.

bobvanluijt··on Weaviate 1.20 Released
* Multi-tenancy – A scalable, efficient and easy solution for use-cases with many tenants per Weaviate cluster.

* PQ + Re-scoring – Product quantization (PQ) allows for faster vector search - now at basically no cost to accuracy!

* Autocut – A new way to set a threshold - set how many groups of results to retrieve from the result set.

* Search re-ranking – Multi-stage search (& re-ranking) for better end results. Multiple re-rankers available!

* New hybrid search ranking algorithm – Additional method available for deriving hybrid search scores.

That depends a bit on the scale and use case specifics. But commoditized billion-scale vector search is indeed a thing. We published this for Weaviate in December last year https://weaviate.io/blog/sphere-dataset-in-weaviate

bobvanluijt··on Ask HN: Seeking a Vector Database for ClickHouse Users – Suggestions Appreciated
Ha, great question! Coincidentally, at Weaviate, we are thinking about this too! There are a few ways to do this with AirByte (https://docs.airbyte.com/integrations/destinations/weaviate/) or (potentially) with Spark (https://github.com/weaviate/spark-connector). Would love to collaborate on this; feel free to reach out over Slack or so.

bobvanluijt··on Faiss: A library for efficient similarity search
Interesting - could it be the case that your use case is more suited for a library like FAISS instead of a vector DB? Would love to understand this. (I’m affiliated with Weaviate).
bobvanluijt··on Faiss: A library for efficient similarity search
Faiss is awesome but note that it's an ANN library that might not be suitable for all use cases; hence vector databases exist. Two things that might be of interest: the main contributor of Faiss on the Weaviate podcast: https://youtu.be/5o1YTp1IL5o and Weaviate as vector DB itself: https://weaviate.io

We are experimenting with Weaviate Embedded so that users can embed the vector database inside their Python (notebook) or TypeScript application. This should help with prototyping, CI pipelines, etc. This request came up a few times from community members, and we are looking for feedback.
