Python Resilience Patterns FAQs

Question 1

What libraries does this skill recommend for Python retries?

Accepted Answer

This skill primarily recommends the Tenacity library for production-grade retry logic due to its flexibility, though it also covers custom lightweight implementations for simpler use cases.

Question 2

Can this skill handle both synchronous and asynchronous Python code?

Accepted Answer

Yes, it includes patterns for both standard synchronous functions and async/await operations, including specific decorators for managing asyncio timeouts and concurrent tasks.

Question 3

When should I use exponential backoff and jitter?

Accepted Answer

You should use them when retrying service calls to give a failing dependency time to recover and to prevent many clients from retrying at the exact same millisecond, which can cause further outages.

Question 4

Does it help with specific HTTP error codes?

Accepted Answer

Absolutely. It provides logic to specifically retry transient status codes like 429 (Too Many Requests), 502, 503, and 504, while ensuring you don't retry permanent errors like 400 Bad Request or 401 Unauthorized.
