> This implementation has only redis adapter yet

Starting with composer
----------------------

[](#starting-with-composer)

`composer require leocarmo/circuit-breaker-php`

Redis adapter
-------------

[](#redis-adapter)

The first argument is a redis connection, the second is your product name, for redis namespace avoid key conflicts with another product using the same redis.

```
use LeoCarmo\CircuitBreaker\CircuitBreaker;

// Connect to redis
$redis = new \Redis();
$redis->connect('localhost', 6379);

$adapter = new \LeoCarmo\CircuitBreaker\Adapters\RedisAdapter($redis, 'my-product');

// Set redis adapter for CB
CircuitBreaker::setAdapter($adapter);
```

Set circuit break settings
--------------------------

[](#set-circuit-break-settings)

> This is not required, default values ​​will be set

```
// Configure settings for CB
CircuitBreaker::setGlobalSettings([
  'timeWindow' => 60, // Time for an open circuit (seconds)
  'failureRateThreshold' => 50, // Fail rate for open the circuit
  'intervalToHalfOpen' => 30, // Half open time (seconds)
]);
```

Configure settings for specific service
---------------------------------------

[](#configure-settings-for-specific-service)

```
// Configure settings for specific service
CircuitBreaker::setServiceSettings('my-custom-service', [
  'timeWindow' => 30, // Time for an open circuit (seconds)
  'failureRateThreshold' => 15, // Fail rate for open the circuit
  'intervalToHalfOpen' => 10, // Half open time (seconds)
]);
```

Check if circuit is available (closed)
--------------------------------------

[](#check-if-circuit-is-available-closed)

Each check is for a specific service. So you can have multiple services in the same application, and when one circuit is open, the other works normally.

```
// Check circuit status for service: `my-service`
if (! CircuitBreaker::isAvailable('my-service')) {
  die('Circuit is not available!');
}
```

Record success and failure
--------------------------

[](#record-success-and-failure)

```
// Usage example for success and failure
try {
  Service::execute('something');
  CircuitBreaker::success('my-service');
} catch (\ServiceException $e) {
  CircuitBreaker::failure('my-service');
  die($e->getMessage());
}
```
