Below is an example route showing an Hystrix endpoint that protects against slow operation by falling back to the in-lined fallback route. By default the timeout request is just 1000ms so the HTTP endpoint has to be fairly quick to succeed.
| Code Block | ||
|---|---|---|

from("direct:start")
.hystrix()
.to("http://fooservice.com/slow")
.onFallback()
.transform().constant("Fallback message")
.end()
.to("mock:result"); |

Hystrix has many options as listed in the table above. For example to set a higher timeout to 5 seconds, and also let the circuit breaker wait 10 seconds before attempting a request again when the state was tripped to be open.
