CircuitBreaker configuration groups

I’d like to be able to define a common configuration for a group of circuit breakers.

Scenario: I have n backends that are independent of each other and should have their own circuit breakers. However, they should have the same config.

It could be configured simliar to the existing config:

resilience4j.circuitbreaker:
    templates:
        group1:
            ringBufferSizeInClosedState: 5
            ringBufferSizeInHalfOpenState: 3
            waitInterval: 5000
            failureRateThreshold: 50
            eventConsumerBufferSize: 10
            registerHealthIndicator: true
            recordFailurePredicate: com.foo.FooRecordFailurePredicate
            recordExceptions:
                - org.springframework.web.client.HttpServerErrorException
            ignoreExceptions:
                - org.springframework.web.client.HttpClientErrorException

And using it could look like circuitBreakerRegistry.circuitBreaker("group1", getHost(serviceUrl); or circuitBreakerRegistry.circuitBreaker("group1." + getHost(serviceUrl);

You can join slack again if you like, I can tell you what’s new and interesting for Ratpack.

Despite the slow pace of releases for Ratpack we are still using it 😃
