Magento 2: how to create your own custom cache type?
This is below some basic structure for create custom cache type,
create one module with,
app/code/Vendor/Cachetype/etc/cache.xml
<?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="custom_cache" translate="label,description" instance="Vendor\Cachetype\Model\Cache\Type">
<label>Custom Cache type</label>
<description>Custom cache description.</description>
</type>
</config>
app/code/Vendor/Cachetype/i18n/en_US.csv
"Custom cache description.","Custom cache description."
"cachetype","Cache type"
app/code/Vendor/Cachetype/Model/Cache/Type.php
<?php
namespace Vendor\Cachetype\Model\Cache;
/**
* System / Cache Management / Cache type "Custom Cache Tag"
*/
class Type extends \Magento\Framework\Cache\Frontend\Decorator\TagScope
{
/**
* Cache type code unique among all cache types
*/
const TYPE_IDENTIFIER = 'custom_cache_tag';
/**
* Cache tag used to distinguish the cache type from all other cache
*/
const CACHE_TAG = 'CUSTOM_CACHE_TAG';
/**
* @param \Magento\Framework\App\Cache\Type\FrontendPool $cacheFrontendPool
*/
public function __construct(\Magento\Framework\App\Cache\Type\FrontendPool $cacheFrontendPool)
{
parent::__construct($cacheFrontendPool->get(self::TYPE_IDENTIFIER), self::CACHE_TAG);
}
}
Thanks.
Would like to edit Rakesh accepted comment, but was rejected....
Anyway here some modifications, additional info to the good answer from Rakesh:
The cache.xml needs to be modfied a little:
<?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="custom_cache_tag" translate="label,description" instance="Vendor\Cachetype\Model\Cache\Type">
<label>Custom Cache type</label>
<description>Custom cache description.</description>
</type>
</config>
So the the name must match the cache_tag.
How to use it, look here: Using Magento 2 custom cache in custom module
To use the data (after being cached) you have to unserialize it:
$data = unserialize($this->_cacheType->load($cacheKey));
