Class KeyedCircuitBreakerMapping<K>

java.lang.Object

com.linecorp.armeria.client.circuitbreaker.KeyedCircuitBreakerMapping<K>

All Implemented Interfaces:

CircuitBreakerMapping

public class KeyedCircuitBreakerMapping<K>
extends Object
implements CircuitBreakerMapping

A CircuitBreakerMapping that binds a CircuitBreaker to its key. KeyedCircuitBreakerMapping.KeySelector is used to resolve the key from remote invocation parameters. If there is no circuit breaker bound to the key, A new one is created by using the given circuit breaker factory.
