The Magento application uses a low-level cache frontend and backend to provide access to the cache storage.
Low-level frontend cache
Magento extends Zend_Cache_Core by implementing Magento\Framework\Cache\Core frontend cache.
Low-level backend cache
In general, the Magento application works with any backend cache that Zend_Cache Backends supports. However, this guide covers only the following low-level backend caches:
- File system (default): No configuration is necessary to use file system caching.
Varnish doesn’t require setting up a low-level cache backend.
We’ll periodically add more low-level cache types so watch this space.
