Circuit Breakers

The Circuit Breaker

• Sony's GoBreaker implementation
• GoBreaker is easy to use
• GoBreaker allows us more direct access to state, and the transitions to and from states
• GoBreaker gives us the ability to fully customize circuit breaker trip conditions.
• Go Hystrix was also evalutated, but proved to be more difficult to control and more difficult to examine state

Go Breaker Settings

func main() {
	const n = 7
	var a = []uint{n:n}
  	fmt.Println(cap(a)) // prints: 8
