When someone says “RAG over millions of PDFs” they’re not asking about AI… they’re asking about search + systems. Here’s what that actually looks like 👇 I’d break it into 5 parts: ingestion, embeddings, retrieval, generation, monitoring 1️⃣ Ingestion is offline, not request-time At scale, this must be async • Stream documents from storage (S3/GCS) • OCR only when needed • Clean + normalize text • Chunk intelligently (not randomly) • Attach rich metadata (doc, page, section, etc.) None of this should ever touch your user request path 2️⃣ Embeddings + indexing built for scale You don’t embed on demand • Batch embedding jobs (GPU or queued) • Distributed ANN indexes (Milvus, Qdrant, Vespa, Elastic) • Sharding + HNSW / IVF / PQ • Store metadata alongside vectors Key insight: metadata filtering is your first gate vector search is the fallback 3️⃣ Retrieval + generation (tight path) Your request path should stay minimal: query → metadata filter → cache → ANN search → rerank → LLM • Most queries never even hit vector search • Many don’t hit the DB at all (cache wins) • Rerank a small set only • Send 5–10 chunks max to the LLM More context ≠ better results More chunks usually hurt 4️⃣ Caching is everything This is what controls cost + latency • Query → answer cache (FAQs, repeats) • Query → retrieval cache (top chunks) • Data/index cache (hot vectors, parsed docs) Real path looks like: query → cache → (miss) retrieve + LLM → write back 5️⃣ Monitoring closes the loop Without this, your system silently degrades • Retrieval quality (recall@k) • Answer quality (feedback loops) • Latency + cache hit rates • Re-embed + re-shard as data evolves BOTTOM LINE: RAG at scale is NOT an LLM problem It’s a search + caching architecture problem Most people are building demos Real AI engineers are building systems Link in bio for the full breakdown + a group with live expert-led calls and systems for you to get hired ASAP
