RAG Vector Embedding Automation (n8n + Pinecone + Gemini)
Built an end-to-end Retrieval-Augmented Generation (RAG) pipeline using n8n to automate the ingestion, processing, and vectorization of documents for intelligent search and AI-powered applications.
This workflow connects Google Drive as a data source, automatically retrieving files from a specified folder and processing them in batches. Each document is downloaded, parsed, and transformed into structured text using a data loader. A recursive character text splitter is then applied to break large documents into optimized chunks, improving embedding quality and retrieval accuracy.
For semantic understanding, the system integrates Google Gemini’s embedding model to convert text chunks into high-dimensional vector representations. These embeddings are then stored in Pinecone, a scalable vector database, using a dedicated namespace to maintain structured and efficient indexing.
The pipeline is designed with scalability in mind, utilizing loop-based batch processing to handle large volumes of documents efficiently without performance bottlenecks. The modular architecture allows easy extension for additional preprocessing steps, filtering logic, or integration with downstream AI systems.
