# REL05-BP03: Control and limit retry calls

## Description

Implement exponential backoff với jitter cho retries.

## Implementation Guidance

- Use exponential backoff (2^n seconds)
- Add jitter to avoid thundering herd
- Set maximum retry attempts
- Implement circuit breaker pattern
- Log retry attempts for debugging

## Risk Level

High - Aggressive retries amplify failures.
