AWS request was throttled

ThrottlingException

AWS throttled the request because the caller exceeded the allowed rate or burst limits for the target API or service operation.

ThrottlingExceptiongeneral

Observed message

ThrottlingException

Why it happens

  • The application is sending too many requests too quickly.
  • Parallel callers are exceeding the API's burst or steady-state limits.
  • Retry behavior is amplifying an already throttled workload.

How to fix it

  1. Implement exponential backoff and jitter for retries.
  2. Reduce concurrency or request rate for the affected API calls.
  3. Review service quotas and request patterns for sustained overuse.
