Loader.load() dispatches to the underlying langchain document loaders (PyMuPDF, Unstructured, python-docx, Tika, …) which are all synchronous and CPU/IO-bound. process_file() awaited it directly on the event loop, so parsing a non-trivial PDF/DOCX would freeze the entire FastAPI app for the duration of the parse — which is what users experience as "the server hangs whenever I upload a file." Add an `aload()` async wrapper on Loader that runs the sync load on a worker thread via asyncio.to_thread, and update process_file() to await it. The sync API is preserved so existing callers that already run inside run_in_threadpool (e.g. save_docs_to_vector_db) are unaffected. https://claude.ai/code/session_01JSr4NZSskEUQvoJnavVXh8 Co-authored-by: Claude <noreply@anthropic.com> |
