I'm exploring Istio's circuit breaker and wan't to setup fallback methods if the circuit trips.

I have a few Spring boot applications that are deployed on kubernetes and with Istio's circuit breaking defined in DestinationRule.

I can see that my caller application gets a 503 Service Unavailable exception when I intentionally bring down the called service.

I'm looking for design patterns or libraries with which I can define fallback methods for my rest calls, something similar to @HystrixCommand.

I checked out spring-cloud-circuitBreaker but that doesn't support Istio. I have also explored ClientHttpRequestInterceptor with Spring RestTemplate, and can catch all ServiceUnavailable exceptions, but I need a way to configure different fallback methods to different REST calls.

Any suggestion is appreciated.

What do you mean by "istio support", as the Istio circuit breaker and spring's one is in fact a difference thing – Sergii Bishyr May 25 '21 at 12:28
