python-idempotent-retry-patterns

What problem does it solve?

This Skill provides robust patterns for implementing retry logic and idempotency safeguards in Python, ensuring reliable network and service calls without duplication or data loss.

Core Features & Use Cases

• Exception-based Retry Logic: Classifies exceptions into retriable and fatal categories for precise retry control.
• Async Backoff with tenacity: Implements exponential jittered backoff for asynchronous operations like HTTP requests.
• Idempotency Enforcement: Manages idempotency keys via headers or message keys to prevent duplicate processing during retries.
• Use Case: Automatically retry failed HTTP requests to a REST API while maintaining idempotent behavior, integrating with HTTPX and Kafka.

Quick Start

Use this Skill to implement retry policies for your async HTTP or Kafka producer code by defining exception predicates, utilizing the provided decorators, and managing idempotency tokens in your requests.
