Section 1
The premise
Vector DB choice depends on your scale, hybrid-search needs, and existing stack — no universal winner.
What AI does well here
- Serve ANN queries at scale (Pinecone, Qdrant).
- Combine vector and metadata filters efficiently.
- Run alongside primary Postgres (pgvector) for small scale.
What AI cannot do
- Match all platforms on every dimension.
- Make migration cheap once your index is loaded.
