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.”
