How do you make Decorators safer under partial failure?

Answers use simple, clear English.

Quick interview answer

Harden Decorators with timeouts, retries with jitter, isolation, and graceful degradation. Mitigate first, then root-cause. Check symptoms against: Forgetting @wraps; decorator not returning wrapper function..

Detailed answer

Resilience for Decorators under partial failure: • Timeouts + budgets on every dependency call • Retries only when idempotent, with jitter/backoff • Isolation: bulkheads/queues so one failure does not cascade • Degradation: serve stale/cached/limited mode when needed Practices: Use wraps; accept *args/**kwargs in generic decorators; prefer parameterized factory pattern. Parent context: Mitigate first, then root-cause. Check symptoms against: Forgetting @wraps; decorator not returning wrapper function..

Full explanation

Partial failure is the default in distributed systems — show how Decorators stays useful anyway. Decorators wrap functions: @decorator applies decorator(func). functools.wraps preserves __name__/__doc__. Common for logging, auth, caching, retries.
