$redisParams = [
    'scheme' => 'tcp',
    'host'   => '127.0.0.1',

];

$config = [
    'params' => $redisParams // Predis/Client $params
    // 'options' => [] // Predis/Client $options
    // 'bucketCount' => DQ::DEFAULT_BUCKET_THREAD
    // 'queueName' => DQ::DEFAULT_QUEUE,
    // 'bucketPrefix' => DQ::DEFAULT_QUEUE_BUCKET,
    // 'partialCount' => DQ::HASH_PARTIAL,
];

$queue = new DQ\Client\Queue($config);
$queue->enqueue(mixed $value [, int $delaySeconds = 0]); // $value will be serialize.

//// enqueue delay
for ($i = 0; $i <= 10000; $i ++) {
    mt_srand($i);
    $dt = mt_rand(0, 100);// delay time seconds.
    $ret = $queue->enqueue([
        'dq' => sprintf('delay value - %07d - %d', $i, $dt),], $dt);

    // if ($i % 10000) {
    //     echo "TEST-", $i, PHP_EOL;
    // }
}

//// dequeue
while (true) {
    $v = $queue->dequeue();
    if ($v) {
        $v = json_encode($v) . PHP_EOL;
