Resilience Patterns

Build systems that survive partial failures and degrade gracefully.

Core Patterns

Retry with Exponential Backoff

import asyncio
import random
from functools import wraps

def retry(max_attempts: int = 3, base_delay: float = 1.0, max_delay: float = 30.0):
    def decorator(func):
        @wraps(func)

                try:
