=== Configuring Hystrix Circuit Breakers
==== Default Configuration
To provide a default configuration for all of your circuit breakers create a `Customize` bean that is passed a
`HystrixCircuitBreakerFactory` or `ReactiveHystrixCircuitBreakerFactory`.
The `configureDefault` method can be used to provide a default configuration.
====
[source,java]
----
@Bean
public Customizer<HystrixCircuitBreakerFactory> defaultConfig() {
return factory -> factory.configureDefault(id -> HystrixCommand.Setter
.withGroupKey(HystrixCommandGroupKey.Factory.asKey(id))
.andCommandPropertiesDefaults(HystrixCommandProperties.Setter()
.withExecutionTimeoutInMilliseconds(4000)));
}
----
====
===== Reactive Example
====
[source,java]
----
@Bean
public Customizer<ReactiveHystrixCircuitBreakerFactory> defaultConfig() {
return factory -> factory.configureDefault(id -> HystrixObservableCommand.Setter
.withGroupKey(HystrixCommandGroupKey.Factory.asKey(id))
.andCommandPropertiesDefaults(HystrixCommandProperties.Setter()
.withExecutionTimeoutInMilliseconds(4000)));
}

==== Specific Circuit Breaker Configuration
Similarly to providing a default configuration, you can create a `Customize` bean this is passed a
`HystrixCircuitBreakerFactory`
====
[source,java]
----
@Bean
public Customizer<HystrixCircuitBreakerFactory> customizer() {
return factory -> factory.configure(builder -> builder.commandProperties(
HystrixCommandProperties.Setter().withExecutionTimeoutInMilliseconds(2000)), "foo", "bar");
}
----

===== Reactive Example

[source,java]
----
@Bean
public Customizer<ReactiveHystrixCircuitBreakerFactory> customizer() {
return factory -> factory.configure(builder -> builder.commandProperties(
HystrixCommandProperties.Setter().withExecutionTimeoutInMilliseconds(2000)), "foo", "bar");
}

Netflix has created a library called https://github.com/Netflix/Hystrix[Hystrix] that implements the https://martinfowler.com/bliki/CircuitBreaker.html[circuit breaker pattern].
