Using Zep as Document Storage?

[mrcrdwd]

I'm using ParentDocumentRetriever, which requires both a Vector Store and a Document Store. Using Zep for the Vector Store is straightforward, but I'm confused about whether or not Zep can also be used as a Document Store (as a replacement for InMemoryStore ). Disclaimer: LangChain is still new to me, so excuse if this is a silly question.

Zep stores both embeddings and the document contents, so you may be able to use Zep's retriever for both of these.

Thanks @danielchalef. The ParentDocumentRetriever it requires a Document Store that implements the BaseStore class. I don't think Zep has an implementation for this, right? Although it sounds like it could be within the scope.

Not planned.
