🚀 The feature

Motivation, pitch

This gives more flexibility to the user to use any vector database of their own choice.

I would like to work on the issue, I have previously worked on the faiss as vector databases for RAG. Could you please specify the requirements needed like whether the integration of embedchain is needed or the notebook/app code is expected.

It would be really great to contribute into this

Hey @Hrishikesh332 , thats great. Looking for integration in the package, like we have other vector db integrated.
