This article presents a comprehensive guide on building a data pipeline that continuously indexes document embeddings into Redis, utilizing various Google Cloud services and LangChain.
The use of a GCP Storage Bucket ensures that all document types are centralised, while Airflow automates the ingestion process from different sources effectively every day.
LangChain's RecordManager is pivotal in managing document embeddings, allowing for both incremental and full indexing, handling updates and deletions seamlessly to maintain data integrity.
This solution ultimately supports a Retrieval-Augmented Generation (RAG) system, enhancing the capability to execute question-answering tasks by indexing dynamically sourced document data.
