FastAPI's asynchronous nature is especially important for RAG scenarios, because document parsing and vector retrieval are both IO-intensive operations, and synchronous frameworks can easily become bottlenecks.

UnverifiedThe pre-parsing layer approach of using specialized tools to segment documents into structured chunks with coordinates before feeding them to an LLM is known as chunk-level RAG architecture, and is one of the mainstream engineering practices for balancing accuracy, cost, and speed.71% similarUnverifiedHidden pitfalls in RAG engineering implementation include retrieval recall rate, chunking strategy, and vector database selection.69% similarUnverifiedThe retrieval step in RAG (embedding plus vector database querying) is typically a CPU-intensive or lightweight GPU task and should be deployed separately from LLM generation.68% similar
