[](#backoffv2-)

---

BackoffV2 is a PHP 5.5+ library implementing various backoff algorithms, such as [exponential backoff](http://en.wikipedia.org/wiki/Exponential_backoff).

This library only returns a backoff delay amount based on the selected algorithms; implementation of the actual delay mechanism (such as [sleep()](http://php.net/manual/en/function.sleep.php)) is left to the user.

---

#### Installation

[](#installation)

Install BackoffV2 with [Composer](https://getcomposer.org/):

`composer require patinthehat/backoffv2`

---

#### Implementation

[](#implementation)

"Jitter" is implemented, if you choose to use it. Jitter is a small, variable amount of time that is added to the backoff amount.

---

Available Jitter algorithms (roughly based on [this post](https://www.awsarchitectureblog.com/2015/03/backoff.html)) include:

- NoJitter - No jitter
- FullJitter - Standard jitter amount
- EqualJitter - More consistent jitter amounts
- DecorrelatedJitter - Higher jitter amounts

---

Backoff algorithms include:

- ExponentialBackoff - exponentially increase the backoff amount
- ConstantBackoff - use the same backoff amount, regardless of the attempt count.
- LinearBackoff - linear increase of the backoff amount, i.e. 1, 2, 3, 4, ...

---

#### Usage

[](#usage)

---

##### Using the Backoff class

[](#using-the-backoff-class)

BackoffV2 implements a main class, `Backoff`, that acts as a container and manager for the backoff and jitter algorithms you choose. The constructor signature for `Backoff` is:

```
public function __construct($maxBackoff, BackoffStrategyInterface $backoff, JitterStrategyInterface $jitter)
```

Usage is simple:

```
include 'vendor/autoload.php';
use BackoffV2\Backoff;
use BackoffV2\Backoff\ExponentialBackoff;
use BackoffV2\Jitter\FullJitter;

$b = new Backoff(15, new ExponentialBackoff, new FullJitter);

echo 'backoff = '.$b->getBackoff() . PHP_EOL;
echo 'backoff = '.$b->getBackoff() . PHP_EOL;
echo 'backoff = '.$b->getBackoff() . PHP_EOL;
echo 'backoff = '.$b->getBackoff() . PHP_EOL;
echo 'backoff = '.$b->getBackoff() . ' (attempt ' . $b->getAttempt().')' . PHP_EOL;
$b->reset();
```
