Overview of cache types

Magento 2 has the following cache types:

Cache type "friendly" name	Cache type code name	Description
Configuration	config	Magento collects configuration from all modules, merges it, and saves the merged result to the cache. This cache also contains store-specific settings stored in the file system and database. Clean or flush this cache type after modifying configuration files.
Layout	layout	Compiled page layouts (that is, the layout components from all components). Clean or flush this cache type after modifying layout files.
Block HTML output	block_html	HTML page fragments per block. Clean or flush this cache type after modifying the view layer.
Collections data	collections	Results of database queries. If necessary, Magento cleans up this cache automatically, but third-party developers can put any data in any segment of the cache. Clean or flush this cache type if your custom module uses logic that results in cache entries that Magento cannot clean.
DDL	db_ddl	Database schema. If necessary, Magento cleans up this cache automatically, but third-party developers can put any data in any segment of the cache. Clean or flush this cache type after you make custom changes to the database schema. (In other words, updates that Magento does not make itself.) One way to update the database schema automatically is using the magento setup:db-schema:upgrade command.
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	Generated HTML pages. If necessary, Magento cleans up this cache automatically, but third-party developers can put any data in any segment of the cache. Clean or flush this cache type after modifying code level that affects HTML output. It’s recommended to keep this cache enabled because caching HTML improves performance significantly.
Reflection	reflection	Removes a dependency between the Webapi module and the Customer module.
Translations	translate	Merged translations from all modules.
Integration configuration	config_integration	Compiled integrations. Clean or flush this cache after changing or adding integrations.
Integration API configuration	config_integration_api	Compiled integration APIs.
Web services configuration	config_webservice	Web API structure.

View the cache status

To view the status of the cache, enter

bin/magento cache:status

A sample follows:

            config: 1
            layout: 1
        block_html: 1
       collections: 1
            db_ddl: 1
               eav: 1
         full_page: 1
         translate: 1
config_integration: 1 config_integration_api: 1
 config_webservice: 1

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 affect on performance.

Starting in version 2.2, you can enable or disable cache types only using the command line. Before doing so, you must manually make <your Magento install dir>/app/etc/env.php writeable by the Magento file system owner.

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

Enabling a cache type automatically clears that cache type.

Clean and flush cache types

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 Magento cache types only. In other words, this option does not affect other processes or applications because it cleans only the cache that Magento uses.

Disabled cache types are not cleaned.
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’ve already tried cleaning the cache and you’re 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
db_ddl
eav
full_page
translate
config_integration
config_integration_api
config_webservice

You can also clean and flush cache types in the Magento 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.
