Hi, I’m trying to save documents that

If you use remote services like mongo or redis, then persisting is not needed

@Rohan but what about embeddings, do I need to redo them each time I use it ?

If the embeddings are stored in mongodb, like you mentioned, then they'll be fetched from there during querying

@Rohan but how can you store the embeddings in mongodb ?

Mongodb might be the worst vector db (since it requires a manual step to create the "index" in the GUI before you can query it)

But there is a small example here
https://docs.llamaindex.ai/en/stable/examples/vector_stores/MongoDBAtlasVectorSearch.html

I would use another vector db tbh

Thanks @Logan M would elastic search be better ? Or what are the OSS I can self host ?

qdrant, chroma, elastic, redis, postgres are all good self-host options
