+   * 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
