Explainer

Downstream APIs and services sometimes fail for a short time, for example with a timeout or a service unavailable error. Fault-tolerant invocation means designing a Mule integration to retry these failures a limited number of times, to stop calling a service that is clearly down, and to park messages that still fail so nothing is lost. Mule provides the Until Successful scope, connector reconnection strategies, the Anypoint MQ circuit breaker, and queue-based retry and reliability patterns for this.
Core information
  • Start by classifying the error. Transient errors, such as a network error, a request timeout or a service unavailable response, can usually be fixed by waiting and retrying. Poisoned messages, such as an authentication error or a resource not found error, never succeed on retry and need manual intervention.
More details and nuances
  • Every Until Successful attempt starts with the same variables and values that existed before the scope. Changes made during a failed attempt are not visible to the next attempt. Only when an attempt succeeds are the variables and payload passed on to the rest of the flow.
