In order to limit the impact of HTTP 429 errors on dependent services in a microservice architecture, here are the strategies you can refer to:

1. Circuit Breaker Pattern

  • Temporarily stop calling the dependent service when repeated 429 errors occur to avoid overloading.

           

2. Retry with Backoff

  • Implement retries with exponential backoff for resilience.

           

3. Rate-Limiting at the Caller Side

  • Limit outgoing requests to avoid hitting rate limits.

4. Graceful Fallbacks

  • Return cached or default responses when 429 errors occur.

           

5. Asynchronous Queues

  • Use queues to delay requests and retry failed ones.

           

Hence, the above strategies can be used to limit the impact of HTTP 429 errors on dependent services in a microservice architecture.​
