CakePHP ORM ::断开数据库连接

I'm using the CakePHP ORM package inside a Gearman Worker. Package : https://packagist.org/packages/cakephp/orm

$connectionObject = ConnectionManager::get('Backend');
$usersTable = TableRegistry::get('Users', ['connection' => $connectionObject]);
$countActiveUsers = $usersTable->find()->where(['active' => 1])->count();

I'm trying to find a way to disconnect the database when a job finish to be processed because now, even if there is no job in the queue, the connection between the worker and the database remains open.

Thanks in advance!

You can use disconnect() on the Connection object.

$connectionObject->disconnect();
