Chain Adapter (chain)

Factory: Cache::chain(array $pools)

Composes multiple PSR-6 pools into a tiered cache.

Behavior:

• writes are propagated to all tiers

• reads search from first tier to last tier

• hit in lower tier is promoted upward

Typical layout:

• L1: in-memory (ArrayCacheAdapter)

• L2: network cache (RedisCacheAdapter)

Example:

use Infocyph\CacheLayer\Cache\Adapter\ArrayCacheAdapter;
use Infocyph\CacheLayer\Cache\Adapter\RedisCacheAdapter;

$cache = Cache::chain([
    new ArrayCacheAdapter('l1'),
    new RedisCacheAdapter('l2'),
]);
