Unleashing the Power of Vector Databases for AI-Driven Applications
summary
Claims a vector database lets apps search by meaning not exact match and power RAG workflows; demonstrates ingesting a CSV into Chroma with a sentence-transformers embedding model, upserting vectors, running semantic queries and returning five nearest neighbors; compares options like Pinecone, Postgres with pgvector and MongoDB Atlas; discusses indexing for millions/billions of vectors and shows the demo runs (minor warnings) and returns reranked results.
