How would you shut down an asyncio service gracefully?

Coordinates admission stop, task cancellation or draining, resource closure, and bounded termination.

TL;DR

I first stop accepting new work, then signal the components that own producers and long-running tasks. Work that can finish within the shutdown budget is drained; remaining cooperative tasks are cancelled and awaited so cleanup and exceptions are observed. Only after task use has ended do I close clients, pools, streams, and the event loop. Shutdown itself has a deadline so deployment cannot hang forever.

Coordinates admission stop, task cancellation or draining, resource closure, and bounded termination.
I first stop accepting new work, then signal the components that own producers and long-running tasks. Work that can finish within the shutdown budget is drained; remaining cooperative tasks are cancelled and awaited so cleanup and exceptions are observed. Only after task use has ended do I close clients, pools, streams, and the event loop. Shutdown itself has a deadline so deployment cannot hang forever.

Stronger answer
Optional upgrade with examples, trade-offs, and sharper phrasing.
The order follows dependencies: stop producers before consumers, stop request admission before closing shared clients, and prevent new retries after shutdown begins. Durable queued work remains persisted for another worker; in-memory best-effort work may be lost according to an explicit policy. I avoid daemon-style abandonment because transactions, files, and telemetry buffers may never be finalized.
