Will Amazon S3 Vectors kill vector databases or save them?

  At a glance, it looks like a lightweight vector database running on top of low-cost object storage—at a price point that is clearly attractive compared to many dedicated vector database solutions.

They also didn’t mention LanceDB, which fits this description but with an open source component: https://lancedb.github.io/lancedb/

This may be because LanceDB is the most attractive with a price point of standard S3 storage ($0.023/GB vs $0.06/GB). I also like that Lancedb works with S3 compatible stores, such as Backblaze B2 which is even cheaper (~70% cheaper).

I love lancedb. It’s the only way I’ve found to performantly and cheaply serve 50m+ records of 768 dimensions. Runs on s3 a bit too slow, but on EFS can still be a few hundred millis.

For low cost, there's also Cloudflare Vectorize ($0.05 per 100 million stored vectors), which nobody seems to know exists: https://www.cloudflare.com/developer-platform/products/vecto...
