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)
|
||
|
|
||
|
```go
|
||
|
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
|
||
|
}
|
||
|
}
|
||
|
```
