I have a redis cluster setup with 3 servers, If i just use the RedisAdapter passing in the Predis client getting and setting keys works as expected, However if i wrap the RedisAdapter in the TagAwareAdapter I am no longer able to retrieve the keys.
$client = new \Predis\Client([
'redis://server1.com',
'redis://server2.com',
'redis://server3.com',
],[
'cluster' => 'redis'
]);
$cache = new RedisAdapter(
$client,
'my_prefix',
60 // 60 second default ttl
);
$tagCache = new TagAwareAdapter($cache);
// Test RedisAdapter
$testItem = $cache->getItem('test_item');
$testItem->set('test_value');
$testSave = $cache->save($testItem);
var_dump($testSaved); //true
$retrieveItem = $cache->getItem('test_item');
var_dump($retrieveItem->isHit()); //true
var_dump($retrieveItem->get()); //test_value
//Test TagAware
$tagItem = $tagCache->getItem('test_tag_item');
$tagItem->set('test_tag_value');
$tagItem->tag('tagged_test')
$tagTestSaved = $tagCache->save($tagItem);
var_dump($tagTestSaved); //true
$retrieveTagItem = $tagCache->getItem('test_tag_item');
var_dump($retrieveTagItem ->isHit()); //false
var_dump($retrieveTagItem ->get()); //null
