The premise
At small scale, a flat in-memory index beats a managed cluster. At large scale, the choice is dominated by ops, not raw speed.
What AI does well here
- Run nearest-neighbor search inside the store you pick.
- Scale horizontally if the store supports it.
What AI cannot do
- Tell you whether you really need a separate vector store at all.
- Make a bad data model fast through indexing alone.
