The semaphore resiliency pattern for golang.
|
||
|
|
|
||
|
|
Creating a semaphore takes two parameters:
|
||
|
|
- ticket count (how many tickets to give out at once)
|
||
|
|
- timeout (how long to wait for a ticket if none are currently available)
|
||
|
|
|
||
|
|
```go
|
||
|
|
sem := semaphore.New(3, 1*time.Second)
|
||
|
|
|
||
|
|
if err := sem.Acquire(); err != nil {
|
||
|
|
// could not acquire semaphore
|
||
|
|
return err
|
||
|
|
}
|
||
|
|
defer sem.Release()
|
||
|
|
```
