circuit-breaker

The circuit-breaker resiliency pattern for golang.

Creating a breaker takes three parameters:

• error threshold (for opening the breaker)
• success threshold (for closing the breaker)

• timeout (how long to keep the breaker open)

  b := breaker.New(3, 1, 5*time.Second)
  
  for {
  	result := b.Run(func() error {
  		// communicate with some external service and
  		// return an error if the communication failed
  		return nil
  	})
  
  	switch result {
  	case nil:
  		// success!
  	case breaker.ErrBreakerOpen:
  		// our function wasn't run because the breaker was open
  	default:
  		// some other error
  	}
  }
