Everyone is piling on you but Id love to see what their companies are doing. Cosine similarity and loading a few thousand rows sounds trivial but most of the enterprise/b2b chat/copilot apps have a relatively small amount of data whose embeddings can fit in RAM. Combine that with natural sharding by customer ID and it turns out vector DBs are much more niche than an RDBMS. I suspect most people reaching for them haven’t done the calculus :/
