This is a rehash (pardon me) of this post from 2021: https://www.search.io/blog/vectors-versus-hashes

The demand for vector embedding models (like those released by OpenAI, Cohere, HuggingFace, etc) and vector databases (like https://pinecone.io -- disclosure: I work there) has only grown since then. The market has decided that vectors are not, in fact, over.

PineCone seems interesting. Is the storage backend open source? I've been working on a persistent hashmap database that's somewhat similar (albeit not done) that should have less RAM requirements than bitcask (ie. larger than RAM keysets)

Although we may open-source parts in the future, currently no part of Pinecone is open-sourced. Instead, there are several proprietary index types available, packaged along with hardware/compute resources into what we call “pods.”
