异步组件在onMessage中频繁的CreateClient和CloseConnect，是否存在浪费连接资源？

require_once __DIR__ . '/vendor/autoload.php';
use Clue\React\Redis\Factory;
use Clue\React\Redis\Client;
use Workerman\Worker;

$worker = new Worker('text://0.0.0.0:6161');

// 进程启动时
$worker->onWorkerStart = function() {
    global $factory;
    $loop    = Worker::getEventLoop();
    $factory = new Factory($loop);
};

$worker->onMessage = function($connection, $data) {
    global $factory;
    $factory->createClient('localhost:6379')->then(function (Client $client) use ($connection) {
        $client->set('greeting', 'Hello world');
        $client->append('greeting', '!');

        $client->get('greeting')->then(function ($greeting) use ($connection){
            // Hello world!
            echo $greeting . PHP_EOL;
            $connection->send($greeting);
        });

        $client->incr('invocation')->then(function ($n) use ($connection){
            echo 'This is invocation #' . $n . PHP_EOL;
            $connection->send($n);
        });
    });
};

Worker::runAll();

有看到官方给出的异步redis例子中是在onMessage中$factory->createClient('localhost:6379')->then()

疑问：每次来一条消息都要去创建一个连接，异步查询，并且用完就关闭该连接是否存在浪费资源？ 请问推荐的最佳实践是怎样的？ 是否将这个连接进行共用？
