Why do I need to specify an uniqueId while initializing \Phalcon\Session\Adapter\Redis ?

use Phalcon\Session\Adapter\Redis;

 $session = new Redis([
     'uniqueId'   => 'my-private-app',
     'host'       => 'localhost',
     'port'       => 6379,
     'auth'       => 'foobared',
     'persistent' => false,
     'lifetime'   => 3600,
     'prefix'     => 'my_'
     'index'      => 1,
 ]);

According to the sample code above, I need to specify an uniqueId for the session. but it made something a little terrible in my code for some reason. I looked over the data has been storaged in redis server and I did't understand why the uniqueId was needed. What should happen if I specify the uniqueId as an empty string ?

I thought it was but the uniqueId is not for the keys in redis. It was only added before every item of the array.
