Not here to schlep for AWS but S3 Vectors is hands down the SOTA here. That combined with a Bedrock Knowledge Base to handle Discovery/Rebalance tasks makes for the simplest implementation on the Market.
Once Bedrock KB backed by S3 Vectors is released from Beta it'll eat everybody's lunch.
S3 Vectors is great in terms of cost. But it provides around 500ms median query latency for 1M vectors, unlike other vector stores. And it does not support keyword search and sparse vectors. So I think it is better to choose which vector store to use based on your requirements.
Assuming that's what he meant, why would it be considered baseline versus anything else? I am genuinely curious because I'd like to know more about issues people face with this or that vector store in general.
