efficient similarity search in kvrocks and faiss library

[adulau]

Something we were wondering: is there any ongoing work on supporting efficient storage in Kvrocks for Faiss?

I remember some earlier work on Redis called Redis Vector Similarity Search, but I'm not sure about its current state.

Would it be completely crazy to store dense vectors in Kvrocks and perform similarity search directly through Kvrocks?

Hi @adulau, Kvrocks Search has been released since 2.11.0, you could give it a shot.

Indeed good point. I don't know how I managed to miss it ;-)

Yeah we have released Kvrocks Search with vector similarity search via HNSW algorithm in 2.11. But note that, it is still quite experimental thus you will probably face some issues. Feel free to try and open issues to us if you encounter problems.

Recently, rocksdb has add FAISS IVF support, facebook/rocksdb#13258 , maybe this can be also used, or just following the "Search" module
