In Part 11 you understood embeddings, and a Python list worked fine — for 10 documents. Reality bites at 1 million: searching a list takes 5 seconds per query, and your user has already clicked away. This part is the **storage layer** of the RAG pipeline. Two concrete solutions in Docker: **Chroma** (Python-native, automatic Ollama embedding plugin, up to ~1M vectors) and **Qdrant** (Rust-based, REST + dashboard, 10M+ vectors). Both stood up with one Docker command, both used from Python, both compared on real features. The middle stone of Phase 3 — in Part 13 (RAG Basics) the LLMs join in, and **your own AI starts answering from your own documents**. 📚 IN THIS PART YOU'LL LEARN ✓ Why a Python list doesn't scale — 4 concrete problems ✓ What a vector DB actually does — store + index + filter ✓ The 5 self-hostable options: Chroma, Qdrant, Weaviate, Milvus, pgvector ✓ Chroma in Docker — one `docker run` command ✓ Chroma Python: HttpClient + OllamaEmbeddingFunction + collection ✓ The structure `query()` returns: ids, documents, distances, metadatas ✓ Metadata + filters: `where={"source":"faq", "year":2025}` ✓ Qdrant in Docker + the built-in dashboard ✓ Qdrant Python: explicit dimension, payload, PointStruct ✓ Chroma vs Qdrant side-by-side comparison ✓ 5 most common vector DB traps (volume mount, dimension mismatch, …) ✓ 4 things to build tonight ⏱️ TIMESTAMPS 00:00 Intro — the storage layer 00:30 Why a list doesn't scale 01:00 What a vector DB does 01:30 The landscape: 5 options 02:00 Chroma in Docker 03:00 Chroma Python — add + query 03:30 What query() returns 04:00 Metadata + filters 05:00 Qdrant in Docker 06:00 Qdrant Python 06:30 Chroma vs Qdrant — pick one 07:00 5 vector DB traps 07:30 4 things to build tonight 08:00 Recap + cheat sheet ⚡ IF THIS WAS HELPFUL 👍 Like — strongest signal to YouTube 🔔 Subscribe + bell — new part every week 💬 Comment — questions, requests, feedback 📤 Share — with anyone learning AI #localai #ollama #vectordb #chroma #qdrant #docker #rag #embeddings #llm #ai #linux #aitutorial #2026ai #dargslan #aifor beginners 🔔 Subscribe for weekly IT insights: https://m.youtube.com/channel/UCv2QLrkCMSBljYG5XKd8IEA About Dargslan: We are dedicated to sharing high-quality, practical IT knowledge.
