Magento uses Zend_Cache to interact with the cache storage. However, Magento also has the Magento\Cache library for implementing Magento-specific caching. These topics discuss how to configure caching and cache types.
By default, file system caching is enabled; no configuration is necessary to use it. This means the cache is located under
<your Magento install dir>/var.
To change the cache configuration, edit
<your Magento install dir>/app/etc/env.php.
The cache configuration is an associative array similar to the following:
'cache_types' => array ( 'config' => 1, 'layout' => 1, 'block_html' => 1, 'collections' => 1, 'db_ddl' => 1, 'eav' => 1, 'full_page' => 1, 'translate' => 1, 'config_integration' => 1, 'config_webservice' => 1, 'config_integration_api' => 1, ), );
The preceding lists all cache types and shows they are all enabled.
