Enhancing AsyncIO for Complex Applications
summary
Explains concrete fixes: use asyncio.run manages the loop (avoid get_event_loop and manual loop.close), schedule work with asyncio.create_task, and use Queue plus Locks/Events/Conditions for coordination; install OS handlers for SIGINT/SIGTERM/SIGHUP, cancel all tasks on shutdown and flush logs/metrics to Sentry so postmortems aren’t blind. Recommends aioconsole and aiomonitor-ng shows long-running tasks (runs in a separate thread, supports 3.10+). For blocking libraries, wrap calls in ThreadPoolExecutor and incrementally port hot paths.
