-----------------------------------
Assignee: Claus Ibsen
> Circuit Breaker EIP - suspend/resume should preserve breaker state
> ------------------------------------------------------------------
>
> Key: CAMEL-24185
> URL: https://issues.apache.org/jira/browse/CAMEL-24185
> Project: Camel
> Issue Type: Improvement
> Components: camel-microprofile-fault-tolerance, eip
> Reporter: Claus Ibsen
> Assignee: Claus Ibsen
> Priority: Minor
>
> Neither FaultToleranceProcessor nor ResilienceProcessor override
> doSuspend()/doResume(), so a route suspend falls through to doStop() which
> resets the circuit breaker state:
> * FT: CircuitBreakerMaintenance.get().reset(id) clears the breaker back to
> CLOSED
> * Resilience4j: circuitBreakerRegistry.remove(id) removes the breaker entirely
> This means a temporarily suspended route loses its OPEN breaker protection.
> When resumed, the breaker starts fresh in CLOSED state, potentially sending
> traffic to a service that was failing moments ago.
> Stop/start resetting state is fine (full lifecycle reset, like a fresh boot).
> But suspend/resume is meant to be lightweight and temporary - breaker state
> should survive it.
> Proposed fix: override doSuspend()/doResume() in both processors to skip the
> breaker cleanup that doStop() performs.
> Related: CAMEL-24136 (umbrella for circuit breaker review findings, finding
> M5).
