Data Ingestion

Prerequisite: Familiarity with the concepts introduced in Part 1 — Golang Orchestration. Review it first if the terminology in this part is unfamiliar. Data Ingestion & Atomic Chunking Product Data: Semantic Catalog Pipelines In general document RAG applications, text splitting divides long articles into arbitrary token chunks (e.g., 512 tokens with 50-token overlap). Applying naive token splitting to e-commerce product catalogs is disastrous. A camera lens catalog page might contain technical specs for three different lens variants (24mm f/1.4, 50mm f/1.2, 85mm f/1.4). Naive character splitting shreds table rows across chunk boundaries, assigning the 24mm lens price to the 85mm lens embedding. ...

Prerequisite: Familiarity with the concepts introduced in Part 1 — Agentic Graphrag Long Context. Review it first if the terminology in this part is unfamiliar. Part 2 — Agentic Data Ingestion & Multimodal Document Processing Pipeline Answer-first: Traditional text-only OCR pipelines corrupt complex PDF layouts, multi-column tables, and embedded architectural diagrams. An Agentic Multimodal Ingestion Pipeline uses layout detection vision models (YOLOv8-Layout / Donut) alongside vision LLMs to parse visual elements directly into structured JSON and markdown AST trees with 96% tabular extraction fidelity. ...
