XF 2.2 Where does XenForo store Redis keys ?

[xml]

Here is my Redis lines in config.php file

$config['cache']['enabled'] = true;
$config['cache']['sessions'] = true;
$config['cache']['provider'] = 'Redis';
$config['cache']['config'] = [
'host' => 'localhost',
'port' => '6379'
];
$config['cache']['namespace'] = 'xf223redis_';

What is the path to Redis keys cache? Does xenforo clear Redis keys by cron entry?
