How sahilbhandare89/high-performance-rag-engine works

This is a Java RAG application whose visible product areas are document ingestion, chunking, and embedding. The apparent user workflow is to submit a document, split it into chunks, and embed chunks; the tree also shows a separate chunking API. The README is empty and no source excerpts are available, so component connections and runtime call order cannot be verified. The graph therefore maps the identifiable product components without asserting unsupported calls or data transfers.
