Context

In How Vector Search Scales by henry.weller@mongodb.com, a new "quantization" field is shown added the to our "vector" indexes. See below. In order for this quantization to work, will the "path" have to be a binary vector subtype? If so, I imagine that the binary values will already have to match the type specified in the quantization, right? To my knowledge, we don't have this work on our roadmap, not even for our langchain repo.

Definition of done

This task is to create binary.from_vector on embedding vectors before storing them in our collections.

Pitfalls

Backward compatibility must be considered. Note that vectors are rarely returned during queries, according to Product team.
