In Magento, the
flush cache and
flush cache storage options are used to clear different types of cache in the system.
flush cache option clears all of the cache types that are enabled in the Magento configuration. This includes full page cache, block HTML output cache, layout cache, and other types of cache that are enabled in the system.
flush cache storage option clears all of the cache stored in the cache storage system, including cache types that may not be enabled in the Magento configuration. This option is useful for clearing out old or stale cache that may be taking up space in the cache storage system.
In general, you should use the
flush cache option when you want to clear the cache for a specific store or website, and you should use the
flush cache storage option when you want to clear all of the cache from the cache storage system.
It is important to note that both of these options can have a significant impact on the performance of your Magento store, as they will cause the system to rebuild the cache when it is next accessed. You should use these options sparingly, and only when necessary to troubleshoot issues or perform maintenance on your store.
