Memcached Cache Storage
If you're getting error that
Memcached class does not exists, then make sure you have properly installed PHP extension
'memcached' => [ 'enabled' => true, 'adapter_class' => '\Koldy\Cache\Adapter\Memcached', 'options' => [ 'servers' => [ // used in addServers method: http://php.net/manual/en/memcached.addservers.php ['localhost', 11211] ], 'persistent_id' => 'koldy', 'adapter_options' =>  ] ]
This value is passed to
Memcached constructor. You can find out more about it here.
The only option that framework will put here by default is
Memcached::OPT_LIBKETAMA_COMPATIBLE => true because it'll
increase compatibility with other systems that may access the same Memcached server. Read more about this
This is not mandatory option, but if it's set, then all keys will be prefixed with this.
