Timeouts

Budget Async Work with asyncio.timeout

Timeouts in asynchronous programs are easy to scatter and surprisingly hard to compose. A service call gets five seconds, a database query gets five more, and a retry gets another five. Each individual limit looks reasonable, yet the whole request can run far beyond the caller’s budget. Python 3.11 added asyncio.timeout(), an asynchronous context manager that makes a different model practical: put a time budget around a block of work, not just around one awaitable.
