Advanced Async Patterns
Beyond basic coroutines, asyncio provides synchronization primitives and utilities for complex concurrent workflows.
Key Utilities
- asyncio.Queue: Producer-consumer pattern
- asyncio.Semaphore: Limit concurrent operations (rate limiting)
- asyncio.TaskGroup: Python 3.11+ structured concurrency (preferred over gather)
- asyncio.timeout: Python 3.11+ timeout context manager
