How to build a better RAG pipeline

Large language models (LLMs), like ChatGPT, are increasingly used for personal productivity but face limitations in business transformation due to their lack of access to real-time, domain-specific data. To overcome this, a strategy called retrieval augmented generation (RAG) has been developed to enhance LLMs by integrating them with proprietary information from various unstructured data sources using vectorization techniques. This process involves creating RAG pipelines, which turn unstructured data into optimized vector search indexes, enabling LLMs to provide more accurate and contextually relevant responses. The implementation of RAG pipelines requires careful consideration of data extraction, chunking, embedding, and synchronization with vector databases to ensure a seamless flow of up-to-date information. The article emphasizes the importance of building resilient, event-driven architectures to handle real-time updates and errors, highlighting the role of platforms like Apache Pulsar in facilitating scalable and reliable data processing.
