In the default installation of Magento 2 Open Source, images, compiled CSS files, and JS files of the Magento instance are saved in the file system on the server. Store administrators can store these files in a database on a database server. This method allows you to select between auto-sync and reverse-sync between the web server file system and the database. You can use the default database to store media or create a new one. To use a newly created database as media storage, you must include information about it and its access credentials in the local .xml file.
The database workflow of using database In Magento 2 media files storage below:
- Browser requests media: The browser requests the media that is specified in the HTML while opening a page in the store on the browser.
- The system looks for media in the file system: The media files will be searched and found in the file system and send to the browser.
- The system locates media in database: If the file is not available in the system, a request is sent to the database that is specified in the configuration.
- The system locates media in database: A PHP script sends the files from the database to the file system and sent to the browser.
If the server is supported and web server rewrites are enabled for Magento, the PHP script runs only when the requested media files are not in the file system.
If the server is not supported or web server rewrites are disabled for Magento, the PHP script runs even if the requested media files exist in the file system.
