Why RAG architecture needs small files

This audio overview explains the following topics using simple, clean, and concise language:1. How does RAG work under the hood? Walk through the inner workings step by step, from the moment we upload knowledge files to when an answer is generated in response to a prompt.2. Which source input works better for RAG: inputting smaller, logically split files or using one consolidated single mega file, and why?3. How do the inner workings of a traditional database (e.g., SQL) differ from those of a vector database used in RAG? Explain why a SQL-based approach would not work effectively in a RAG system.
