Vert.x Circuit Breaker is an implementation of the Circuit Breaker _pattern_ for Vert.x. More details on this pattern on https://en.wikipedia.org/wiki/Circuit_breaker_design_pattern

It keeps track of the

number of failures and _opens the circuit_ when a threshold is reached. Optionally, a fallback is executed.

Supported failures are:

* failures reported by your code

* exception thrown by your code

* uncompleted futures (timeout)

Operations guarded by a circuit breaker are intended to be non-blocking and asynchronous in order to benefit from

the Vert.x execution model.

== Using the Vert.x Circuit Breaker

To use the Vert.x Circuit Breaker, add the following dependency to the _dependencies_ section of your build

descriptor:

* Maven (in your `pom.xml`):

----

  io.vertx

  vertx-circuit-breaker

  $VERSION

----

* Gradle (in your `build.gradle` file):

----

compile 'io.vertx:vertx-circuit-breaker:$VERSION'

----
