在单一进程下，所有协程共享workerman的mqtt连接来发送数据是否可行？

$worker->onWorkerStart = function ($worker) {
            try {
                $mqttClient = new \Workerman\Mqtt\Client(env('MQTT_URL'), ['client_id' => "sy-mqtt-client-".mt_rand(), 'username' => env('MQTT_USERNAME'), 'password' => env('MQTT_PASSWORD'), 'protocol_level' => 5]);
                $mqttClient->connect();
                for ($n=1; $n<=50; $n++) {
                    Coroutine::create(function () use ($mqttClient) {
                        $mqttClient->publish('test/whd/123/r', 'ok test';
                    });
                }
