Cache types

You can use the Adobe Commerce cache management system to improve the performance of your site. This topic explains how System administrators or developers with access to the Commerce application server can manage caches from the command line.

NOTE
Commece site administrators can manage the cache from the Admin using the Cache Management System tool. See Cache Management in the Admin Systems Guide.

View the cache status

From the command line of the Commerce application server, view the status of the cache using the cache:status Commerce CLI command.

   bin/magento cache:status

A sample follows:

Current status:
                        config: 1
                        layout: 1
                    block_html: 1
                   collections: 1
                    reflection: 1
                        db_ddl: 1
               compiled_config: 1
             webhooks_response: 1
                           eav: 1
         customer_notification: 1
 graphql_query_resolver_result: 1
            config_integration: 1
        config_integration_api: 1
                  admin_ui_sdk: 1
                     full_page: 1
                   target_rule: 1
             config_webservice: 1
                     translate: 1
TIP
For a detailed description of the default cache types supported by Adobe Commerce, see Caches in the Admin Systems Guide.

Enable or disable cache types

This command enables you to enable or disable all cache types or only the ones you specify. Disabling cache types is useful during development because you see the results of your changes without having to flush the cache; however, disabling cache types has an adverse effect on performance.

INFO
Starting in version 2.2, you can only enable or disable cache types using the command line while running Commerce in production mode. If running Commerce in developer mode, you can enable or disable cache types using the command line or manually. Before doing so, you must manually make <magento_root>/app/etc/env.php writeable by the file system owner.

You can clean (also referred to as flush or refresh) cache types using either the command line or the Admin.

Command options:

bin/magento cache:enable [type] ... [type]

bin/magento cache:disable [type] ... [type]

Where omitting [type] enables or disables all cache types at the same time. The type option is a space-separated list of cache types.

To list cache types and their status:

bin/magento cache:status

For example, to disable the full page cache and the DDL cache:

bin/magento cache:disable db_ddl full_page

Sample result:

   Changed cache status:
       db_ddl: 1 -> 0
    full_page: 1 -> 0
INFO
Enabling a cache type automatically clears that cache type.
INFO
As of version 2.3.4, Commerce caches all system EAV attributes as they are retrieved. Caching EAV attributes in this manner improves performance, because it decreases the amount of insert/select requests to the DB. However, it increases cache network size as well. Developers can cache custom EAV attributes by running the bin/magento config:set dev/caching/cache_user_defined_attributes 1 command. This can also be done from the Admin while in Developer mode by setting Stores > Settings Configuration > Advanced > Developer > Caching Settings > Cache User Defined Attributes to Yes.

Clean and flush cache types

NOTE
Multiple pages cache can be invalidated simultaneously and automatically without these entities editing. For example, when any product in the catalog is assigned to any category, or when any related product rule is modified.

To purge out-of-date items from the cache, you can clean or flush cache types:

  • Cleaning a cache type deletes all items from enabled Commerce cache types only. In other words, this option does not affect other processes or applications because it cleans only the cache that Commerce uses.

    Disabled cache types are not cleaned.

    TIP
    Always clean the cache after upgrading versions of Adobe Commerce, upgrading from Magento Open Source to Adobe Commerce, or installing B2B for Adobe Commerce or any module.

  • Flushing a cache type purges the cache storage, which might affect other processes applications that are using the same storage.

Flush cache types if you have already tried cleaning the cache and you are still having issues that you cannot isolate.

Command usage:

   bin/magento cache:clean [type] ... [type]

   bin/magento cache:flush [type] ... [type]

Where [type] is a space-separated list of cache types. Omitting [type] cleans or flushes all cache types at the same time. For example, to flush all cache types, enter

   bin/magento cache:flush

Sample result:

   Flushed cache types:
   config
   layout
   block_html
   collections
   reflection
   db_ddl
   compiled_config
   eav
   customer_notification
   config_integration
   config_integration_api
   full_page
   graphql_query_resolver_results
   config_webservice
   translate
TIP
You can also clean and flush cache types in the Admin. Go to System > Tools > Cache Management. Flush Cache Storage is equivalent to bin/magento cache:flush. Flush Magento Cache is equivalent to bin/magento cache:clean.
