Do such vector-search databases have a sizable market, say > 10B? It looks only a few big players would need such technology: search engines, security companies, LexisNexis (maybe). But for most of companies, their dataset is small enough that an in-memory library like faiss may well just do the work. And if such database becomes so useful, I'd imagine that software like Solr or ES can simply replace their current implementation of ANN search with a better version.
