class EntityFieldStorageConfig

Provides destination plugin for field_storage_config configuration entities.

The Field API defines two primary data structures, FieldStorage and Field. A FieldStorage defines a particular type of data that can be attached to entities as a Field instance.

The example below creates a storage for a simple text field. The example uses the EmptySource source plugin and constant source values for the sake of simplicity.

id: field_storage_example
label: Field storage example
source:
plugin: empty
constants:
  entity_type: node
  id: node.field_text_example
  field_name: field_text_example
  type: string
  cardinality: 1
  settings:
    max_length: 10
  langcode: en
  translatable: true
process:
  entity_type: constants/entity_type
  id: constants/id
  field_name: constants/field_name
  type: constants/type
  cardinality: constants/cardinality
  settings: constants/settings
  langcode: constants/langcode
  translatable: constants/translatable
destination:
  plugin: entity:field_storage_config

For a full list of the properties of a FieldStorage configuration entity, refer to \Drupal\field\Entity\FieldStorageConfig.

For an example on how to migrate a Field instance of this FieldStorage, refer to \Drupal\migrate\Plugin\migrate\destination\EntityFieldInstance.
