Provides a high-level interface ( ThreadPoolExecutor , ProcessPoolExecutor ) to manage execution pools cleanly.
Decorators provide a clean way to inject cross-cutting concerns—such as logging, caching, and authorization check logic—without cluttering core business functions. When a PDF is a scanned image (a

One of the most powerful features in the modern toolkit is the . When a PDF is a scanned image (a raster scan), the text is not digitally selectable. You can now build pipelines that automatically detect the need for OCR and process it using engines like Tesseract or PaddleOCR. Kreuzberg and PyMuPDF4LLM integrate this functionality, allowing you to treat scanned and text-based PDFs identically.
