Cozodb as a vector store for llama index or langchain

[nickdickinson]

I am interested in using cozodb as a vector and graph store. Are there any vector and document store interfaces for langchain or llama index that would facilitate integration? Is there interest in this if I would develop it?

This is a duplicate of the discussion here but unsure how discussions work so putting it here as I think more people will be able to engage under issues (please correct me if I'm wrong and feel free to delete): #237
