Delegates the RAG pipeline to external services instead of running it in-process: - Ingestion: when EXTERNAL_INGESTION_ENGINE=external, uploaded files are sent to the ingestion service (S3 reference or multipart), which handles text extraction, chunking, embedding and vector storage. File deletes notify the service so vectors don't outlive the file (best-effort, never blocks the user's delete). - Retrieval: when RAG_RETRIEVAL_ENGINE=external, document search goes to the retrieval service instead of the built-in vector DB, on both the chat files path and the native function calling path (query_knowledge_files). Optionally bypasses local query generation and forwards the recent conversation so the service can generate its own queries (RAG_EXTERNAL_MESSAGE_COUNT / USER_MESSAGES_ONLY). - Admin UI for both engines under Settings > Documents. Both engines are off by default; behaviour is unchanged from stock open-webui unless enabled. See https://github.com/AarhusAI/ingestion-service and https://github.com/AarhusAI/retrieval-agent.
