faiss-cpu / vector DB

[tushar-31093]

Hi, I had a general query. I am working on an FAQs based application for my projects. This aspect that you have built seems quite useful thus exploring the same. I wanted to understand where is faiss-cpu vector store stored after the embeddings etc have been generated? Does is persist only in the memory? and if i put down the app, the data is gone until I run it again? is that how it works?

If not, then does it append all new data from the new files to the previous vector store and consequently that is used? Can you please elaborate on the flow for me?
