Phalcon framework, how does redis switch databases?

ModelsCache configuration: {code ...} during service injection, you can specify the database storage by configuring the index parameter. you can see that the API has a setOptions function, and try to switch the following code from the current db0 to db1, but all the data is stored in db0 and there is no switchover. what should I do... modelsCacheThe configuration is as follows:

$di->set('modelsCache', function () use ($config) {    $cache = new Phalcon\Cache\Backend\Redis(xx, xx);    return $cache;});

Configure parameters during service injectionindexYou can select the specified library storage to view the API.setOptionsFunction, trying to code below a remote line
Todb0, Switchdb1But all data is storeddb0No switchover. how can I change the database at any time ??

$this->modelsCache->save('data_in_db0','value');$opt=$this->modelsCache->getOptions();$opt['index']=1;$this->modelsCache->setOptions($opt);$this->modelsCache->save('data_in_db1','value');
