Amazon AWS PHP SDK with Guzzle's MultiCurl?

问题:

I need to perform some fairly heavy queries with Amazon's AWS SDK for PHP.
The most efficient way would be to use PHP's MultiCurl. It seems that Guzzle already has functionality for MultiCurl built in.

Does using the standard methods provided by the AWS SDK automatically use MultiCurl or do I have to specify it's usage directly? E.g. calling $sns->Publish() 30 times.

Thanks!

Parallel requests work exactly the same in the SDK as in plain Guzzle and do take advantage of MultiCurl. For example, you could do something like this:

$message = 'Hello, world!';
$publishCommands = array();
foreach ($topicArns as $topicArn) {
    $publishCommands[] = $sns->getCommand('Publish', array(
        'TopicArn' => $topicArn,
        'Message'  => $message,
    ));
}

try {
    $successfulCommands = $sns->execute($publishCommands);
    $failedCommands = array();
} catch (\Guzzle\Service\Exception\CommandTransferException $e) {
    $successfulCommands = $e->getSuccessfulCommands();
    $failedCommands = $e->getFailedCommands();
}

foreach ($failedCommands as $failedCommand) { /* Handle any errors */ }

$messageIds = array();
foreach ($successfulCommands as $successfulCommand) {
    $messageIds[] = $successfulCommand->getResult()->get('MessageId');
}
