Kohana Cache

The default cache group is loaded based on the Cache::$default setting. It is set to the file driver as standard, however this can be changed within 
the /application/boostrap.php file
// Change the default cache driver to memcache
Cache::$default = 'memcache';

// Load the memcache cache driver using default setting
$memcache = Cache::instance();

　　

动态切换缓存方式为file

$key = 'AjSR/piQT24JaYEgh6V9tA==';
$data = array('id'=>1, 'name'=>'liuchao');
Cache::instance("file")->set($key, $data, 60);
print_r(Cache::instance("file")->get($key));
//Cache::instance("file")->set($key, $data, (CFG_DEBUG?-1:60));

60
a:2:{s:2:"id";i:1;s:4:"name";s:7:"liuchao";}

kohana缓存实际应用及优化

E:\html\tproject\framebota\platform\bootstrap.php

if (class_exists('memcache')) {
    Cache::$default = 'memcache'; // default is File set to Memcache
}

E:\html\tproject\framebota\platform\libraries\Uploader\General.php

line 52

$this->_url = ORM::factory('Platform', 8)->cached(3600)->get('p'.CFG_PLATE);

SELECT * FROM bota_platform WHERE id = 8;

可以优化为：

        $urlpre = '';
        $key = 'cache_cdns_url';
        if(Cache::instance("file")->get($key)){
            $urlpre = Cache::instance("file")->get($key);
        }else{
            $urlpre = BOTA::url('com.bota.cdns');
            Cache::instance("file")->set($key, BOTA::url('com.bota.cdns'), 3600);
        }
