Any online business owner is going to be concerned about performance. Luckily, the team at Magento regularly contributes the best solutions that benefit store owners within a fast-paced ecommerce ecosystem.Â
In fact, I’d call Magento a never-ending product, with a variety of ever-increasing operations. In that vein, this blog is meant to give some insight into Magento 2 cache operations.
So without further ado, let’s take a look at the Magento 2 cache.
What is the Magento 2 Cache?
As you probably know, the cache is one of the easiest, quickest, and most effective ways to optimize website performance. Magento fulfills almost all the essential types of caches required for an ecommerce store. It allows the user to enable and disable caches through a single command line.

Magento 2 Cache Types
The table below describes the various cache types that Magento supports.
| Cache Type | Variable | Description |
|---|---|---|
| Configuration | config | This cache contains store-specific settings in the file system and database. Magento collects configuration from all the modules, merges it, and saves the merged result to the cache for better store performance. |
| Layout | layout | It helps clean or flush this cache type after modifying layout files. |
| Block HTML output | block_html | This cache cleans or flushes HTML page fragments per block type after modifying the view layer. |
| Collections data | collections/td> | This helps cache results of database queries. It cleans or flushes if your custom module uses logic that results in cache entries Magento cannot clean. |
| DDL | db_ddl | This cache is related to the Database schema. It cleans or flushes when you make custom changes to the database schema. One way to automatically update the database schema is by using the Magento setup:db-schema:upgrade command. |
| Compiled Config | compiled_config | Compilation configuration |
| Entity attribute value (EAV) | eav | Metadata related to EAV attributes (for example, store labels, links to related PHP code, attribute rendering, search settings, and so on). You should not typically need to clean or flush this cache type. |
| Page cache | full_page | Magento cleans up this cache automatically, but third-party developers can put any data in any segment of the cache. It cleans or flushes after modifying code levels affecting HTML output. It is recommended to keep this cache enabled. |
| Reflection | reflection | Removes a dependency between the WebAPI module and the Customer module. |
| Translations | translate | After merging translations from all modules, the merger cache will be cleaned. |
| Integration configuration | config_integration | It cleans or flushes this cache after changing or adding integrations. |
| Integration API configuration | config_integration_api | Compiled integration APIs configuration of the store’s integrations. |
| Web services configuration | config_webservice | It helps in caching the Web API Structure. |
| Customer Notification | customer_notification | Temporary notifications that appear in the user interface. |

Recommended Cache Technologies for Magento Server
Magento recommends a couple of cache technologies to optimize store performance. When you look for a Magento store, ensure the hosting provider has these caches enabled with the Magento server.
Varnish Cache
Designed as an HTTP accelerator, Varnish enhances the performance of heavy content web applications like Magento. Therefore, the Varnish cache is part of the Cloudways hosting stack.
Memcached
Memcached is an open-source distributed memory caching system. It reduces that load by storing data objects in dynamic memory – short-term memory for web applications. Memcache configuration is also an integrated part of the Cloudways hosting stack.
Redis CacheRedis is an open-source (BSD licensed) used as a database, cache, and message broker. It provides data structures such as strings, hashes, lists, sets, sorted sets with range queries, bitmaps, hyperlogs, geospatial indexes, and streams. You can install/uninstall the Redis cache via the Cloudways dashboard.
PHP OPCachePHP OPCache is also recommended by Magento officially. It compiles and caches PHP scripts to bytecode instead of compiling on every request. That’s how it improves overall application performance.
In short, you need to take care of these Magento cache and server technologies to experience faster store performance.
