class Config

Drupal 8+ configuration source from database.

Available configuration keys:

• collections: (optional) The collection of configuration storage to retrieve from the source - can be a string or an array. If omitted, configuration objects of all available collections are retrieved.
• names: (optional) Names of configuration objects to retrieve from the source - can be a string or an array. If omitted, all available configuration objects are retrieved.

Examples:

source:
  plugin: d8_config
  names:
    - node.type.article
    - node.type.page

In this example configuration objects of article and page content types are retrieved from the source database.

source:
  plugin: d8_config
  collections: language.fr
  names:
    - node.type.article
    - node.type.page

In this example configuration objects are filtered by language.fr collection. As a result, French versions of specified configuration objects are retrieved from the source database.

For additional configuration keys, refer to the parent classes.
