Database / PineCone Database Interview questions

How does Pinecone's upsert operation work, and what happens if you upsert an existing vector ID?

The upsert operation in Pinecone inserts new vectors or updates existing ones if the vector ID already exists. This ensures that the latest vector and metadata are stored for each unique ID.
