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
	}
}
