Configure caching

Set up the following cache mechanisms in the Commerce configuration:

• Database
• Redis
• File system (default): No configuration is necessary to use default file system caching.

Set up the Varnish without modifying the Commerce configuration.

Frontend—Similar to an interface or gateway to cache storage, implemented by Magento\Framework\Cache\Frontend.

Cache types—Can be one of the types provided with Commerce or you can create your own.

Backend—Specifies details about cache storage, implemented by Magento\Framework\Cache\Backend

Two-level backend—Stores cache records in two backends: a faster one and a slower one.

INFO

Two-level backend cache configuration is beyond the scope of this guide.

Modifying the provided default cache frontend—

You modify only the <magento_root>/app/etc/di.xml file, the Commerce application’s global dependency injection configuration.

Configuring your own custom cache frontend—

You modify only the <magento_root>/app/etc/env.php file because it overrides the equivalent configuration in the di.xml file.
