  /**
   * Gets the destination IDs.
   *
   * To support MigrateIdMap maps, derived destination classes should return
   * field definition(s) corresponding to the primary key of the destination
   * being implemented. These are used to construct the destination key fields
   * of the map table for a migration using this destination.
   *
   * @return array[]
   *   An associative array of field definitions keyed by field ID. Values are
   *   associative arrays with a structure that contains the field type ('type'
   *   key). The other keys are the field storage settings as they are returned
   *   by FieldStorageDefinitionInterface::getSettings(). As an example, for a
   *   composite destination primary key that is defined by an integer and a
   *   string, the returned value might look like:
   *   @code
   *     return [
   *       'id' => [
   *         'type' => 'integer',
   *         'unsigned' => FALSE,
   *         'size' => 'big',
   *       ],
   *       'version' => [
   *         'type' => 'string',
   *         'max_length' => 64,
   *         'is_ascii' => TRUE,
   *       ],
   *     ];
   *   @endcode
   *   If 'type' points to a field plugin with multiple columns and needs to
   *   refer to a column different than 'value', the key of that column will be
   *   appended as a suffix to the plugin name, separated by dot ('.'). Example:
   *   @code
   *     return [
   *       'format' => [
   *         'type' => 'text.format',
   *       ],
   *     ];
   *   @endcode
   *   Additional custom keys/values, that are not part of field storage
   *   definition, can be passed in definitions:
   *   @code
   *     return [
   *       'nid' => [
   *         'type' => 'integer',
   *         'custom_setting' => 'some_value',
   *       ],
   *     ];
   *   @endcode
   *
   * @see \Drupal\Core\Field\FieldStorageDefinitionInterface::getSettings()
   * @see \Drupal\Core\Field\Plugin\Field\FieldType\IntegerItem
   * @see \Drupal\Core\Field\Plugin\Field\FieldType\StringItem
   * @see \Drupal\text\Plugin\Field\FieldType\TextItem
