Create a cache type | Magento 2 Developer Documentation

A cache type enables you to specify what is cached and enables merchants to clear that cache type using the Cache Management page in the Magento Admin.

The tag scope provides a mechanism for a cache type.

Cache type configuration

Declare a new cache type in the etc/cache.xml file with the following attributes:

Attribute	Required?	Description
`name`	Yes	A unique cache type ID
`translate`	No	Parameters that will be translated on the “Cache Management” page
`instance`	Yes	The cache type model class

Also, cache type configuration have the following required parameters:

Parameter	Description
`label`	The “Cache Type” field to be displayed on the `System` > `Tools` > `Cache Management` page.
`description`	The “Description” field to be displayed on the `System` > `Tools` > `Cache Management` page.

For example:

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Cache/etc/cache.xsd">
    <type name="%cache_type_id%" translate="label,description" instance="VendorName\ModuleName\Model\Cache\Type\CacheType">
        <label>Cache Type Label</label>
        <description>Cache Type Description</description>
    </type>
</config>

You may declare multiple cache types.

Cache type model

<?php
namespace VendorName\ModuleName\Model\Cache\Type;

use Magento\Framework\App\Cache\Type\FrontendPool;
use Magento\Framework\Cache\Frontend\Decorator\TagScope;

/**
 * System / Cache Management / Cache type "Your Cache Type Label"
 */
class CacheType extends TagScope
{
    /**
     * Cache type code unique among all cache types
     */
    const TYPE_IDENTIFIER = '%cache_type_id%';

    /**
     * The tag name that limits the cache cleaning scope within a particular tag
     */
    const CACHE_TAG = '%CACHE_TYPE_TAG%';

    /**
     * @param FrontendPool $cacheFrontendPool
     */
    public function __construct(FrontendPool $cacheFrontendPool)
    {
        parent::__construct(
            $cacheFrontendPool->get(self::TYPE_IDENTIFIER),
            self::CACHE_TAG
        );
    }
}

You must specify the following parameters:

VendorName\ModuleName defines the name of a module that uses a cache type. A module can use several cache types and a cache type can be used in several modules.
%cache_type_id% defines the unique identifier of a cache type.
%CACHE_TYPE_TAG% defines the unique tag to be used in the cache type scoping.
