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):

• Gradle (in your build.gradle file):

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