This is a PSR-6 cache implementation using a chain of other PSR-6 cache pools. It is a part of the PHP Cache organisation. To read about features like tagging and hierarchy support please read the shared documentation at www.php-cache.com.

composer require cache/chain-adapter

You do not need to do any configuration to use the CachePoolChain.

$redisPool = new RedisCachePool($redisClient);
$apcPool = new ApcCachePool();
$pool = new CachePoolChain([$apcPool, $redisPool]);
