Answer 4

It's best to use Tags for this cache, so it's possible to do one cache flush for a whole bunch of keys and queries

$tag = 'Customer-' . $id;                           // готовим таг
  $ttl = 60 * 60 * 24 * 4;                            // готовим время жизни кеша

   $result = Customer::getDb()->cache(function ($db) use ($id) {
           return Customer::findOne($id);
   }, $ttl, new TagDependency(['tags' => $tag]));      // Пометка тагом данного кеша
                
 TagDependency::invalidate(Yii::$app->cache,$tag);   // Очистка всех кешей с данным тагом
