Ask Astro is a project designed to operationalize data ingestion for Retrieval Augmented Generation (RAG) applications using large language models (LLMs), specifically focusing on the integration of Apache Airflow and vector databases like Weaviate. The project began as a prototype to efficiently leverage vast amounts of documentation within open-source communities and has evolved to highlight the importance of modularity and experimentation in building scalable and reliable RAG applications. Key considerations include selecting the right vector store for scalability, optimizing schema design, and choosing an effective chunking strategy for documents. The architecture uses LangChain for simplifying backend and frontend processes and employs modular components for data extraction, document splitting, and ingestion. The project emphasizes the need for a flexible infrastructure that supports rapid experimentation and iteration, vital for keeping up with the fast-paced innovations in LLMs and RAG applications. Future series installments will explore advanced topics such as hybrid search and prompt engineering, aiming to enhance the RAG application framework further.
