Streamlit async operations require careful handling due to synchronous execution model
Streamlit’s architecture fundamentally relies on a synchronous, top-to-bottom execution model. It reruns scripts on each user interaction. This creates significant challenges for implementing long-running async tasks and background processes. While Streamlit does not officially support multithreading in application code as of 2025, the framework has made notable improvements. These include event loop reuse (v1.31+), async generator support in st.write_stream, and fragment-based partial updates that enable more sophisticated async patterns.
