PDFs Are the New CSVs — Building Parsing Pipelines That Scale to Millions

Modern enterprises store critical business knowledge in PDFs, making document parsing a core data engineering challenge. Scalable parsing pipelines use OCR, layout detection, metadata extraction, and distributed processing to transform millions of unstructured documents into searchable, AI-ready data for analytics and RAG systems.
