Resilient Task Runner, A circuit breaker implementation, highly configurable task runner with number of max retries, back-off factor, maximum sleep time, and starting sleep time.


Install the `eshta/resilient-task` package:

$ composer require eshta/resilient-task


use GuzzleHttp\Exception\ConnectException;

$task = function() {
    try {
        $response = $client->request('GET', '');

        return $response;
    } catch (ConnectException $e) {
        echo Psr7\str($e->getRequest());

$runner = new ResilientTaskRunner(10, 16, 0.5);
$response = $runner->run($task);

if (is_null($response)) {
    throw new MyFavouriteException('Service call failed!');
  • try 10 times at most
  • maximum sleep time between retries 16 seconds
  • first sleep time is half a second
  • back-off factor [2 default]: double sleeping time after each failed attempt

Note:: the runner will only stop when there is a non-null result returned by the task, or the max tries have been exhausted
