An ETL task sometimes fails because of temporary throttling.
Quarantine permanent input errors immediately and avoid infinite retries.
Which automation approach is most appropriate?
Classify errors, configure bounded Retry with exponential backoff, and use Catch to isolate permanent failures.
Detailed explanation
Transient errors can retry with a limit, while validation errors take a separate failure path.

Recording text alone does not retry, notify, or control the workflow.

Foundation review
Exponential backoff
Increasing delays reduce pressure on a dependency that may be recovering.
Permanent error
Bad input or missing permission normally needs correction rather than another attempt.
